The correct answer is: In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity.

Transpiration and photosynthesis are both processes that involve the use of water by plants.

Transpiration is the process by which water evaporates from the leaves of a plant and is released into the atmosphere. This occurs through tiny openings on the surface of leaves called stomata. The water that is lost through transpiration is replaced by water absorbed by the roots of the plant from the soil.

Photosynthesis, on the other hand, is the process by which plants use water, along with carbon dioxide and sunlight, to produce oxygen and glucose. During photosynthesis, water is split into hydrogen and oxygen, and the oxygen is released into the atmosphere as a byproduct. The glucose that is produced is used as a source of energy by the plant.

In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.

3. a) One possible mechanism for this reaction is: 3 Fe + 4 H₂O ⇌ Fe₃O₄ + 4 H₂

b) A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent chemical change itself.

c) second-order reaction.

4. a) The expression of the equilibrium constant for the given reaction is:

Kc = ([Fe₃O₄][H₂]⁴) / ([Fe]³[H₂O]⁴)

b) Increasing the pressure will favor the indirect reaction and slow down the direct reaction.

c) Since the indirect reaction is favored by the increased pressure, the chemical equilibrium will shift to the right, towards the product side.

The method of initial rates involves measuring the initial rate of the reaction under different initial concentrations of the reactants. By comparing the initial rates, we can determine the order of the reaction with respect to each reactant.

Assuming that the rate law of the reaction is:

rate = k[Fe]^x[H₂O]^y

where k is the rate constant, and x and y are the orders of the reaction with respect to Fe and H2O, respectively.

Experimentally, measure the initial rate of the reaction under different initial concentrations of Fe and H₂O while keeping the concentration of the other reactant constant.

For example, suppose we measure the initial rates of the reaction at the following initial concentrations:

Experiment #1: [Fe] = 0.1 M, [H₂O] = 0.2 M, initial rate = 0.005 M/s

Experiment #2: [Fe] = 0.2 M, [H₂O] = 0.2 M, initial rate = 0.02 M/s

Experiment #3: [Fe] = 0.4 M, [H₂O] = 0.2 M, initial rate = 0.08 M/s

Use the rate data to determine the orders of the reaction with respect to Fe and H₂O. To do this, we compare the initial rates of the reaction under different initial concentrations of Fe and H₂O while keeping the concentration of the other reactant constant.

Suppose we double the concentration of Fe while keeping the concentration of H₂O constant. According to experiment 2 and experiment 1, the rate of the reaction doubles. This means that the order of the reaction with respect to Fe is 1.

Similarly, if we double the concentration of H₂O while keeping the concentration of Fe constant, we can see that the rate of the reaction doubles from experiment 1 to experiment 3. This means that the order of the reaction with respect to H₂O is also 1.

Therefore, the overall order of the reaction is the sum of the orders of the reactants, which is:

overall order = 1 + 1 = 2

Hence, the given reaction is a second-order reaction.

The triiodide ion, I3−, is a polyatomic anion composed of three iodine atoms. It has a central iodine atom, which is surrounded by two other iodine atoms in a trigonal planar geometry. The hybridization of the central atom is sp2. This is because the central atom has 3 electron pairs in its valence shell, which means it needs to form three bonds with the other atoms. This requires the central atom to use one s-orbital and two p-orbitals to form three sp2 hybrid orbitals. These three sp2 orbitals are then used to form the three bonds with the other two iodine atoms, resulting in a trigonal planar geometry.

A)law of multiple proportions

Explanation:

Answer:

The Clausius-Clapeyron equation is given by:

ln(P2/P1) = -(ΔHvap/R) * (1/T2 - 1/T1)

where P1 and T1 are the vapor pressure and temperature of the substance at one point, P2 and T2 are the vapor pressure and temperature at another point, ΔHvap is the enthalpy of vaporization, and R is the gas constant.

We can use this equation to find the vapor pressure of methanol at 73.5°C, given the vapor pressure of water at 100.0°C.

First, we convert the temperatures to Kelvin:

T1 = 100.0°C = 373.2 K

T2 = 73.5°C = 346.7 K

Next, we substitute the values into the equation, along with the enthalpy of vaporization for methanol and the gas constant:

ln(P2/101.3 kPa) = -(35.2 kJ/mol / 8.314 J/(mol*K)) * (1/346.7 K - 1/373.2 K)

Simplifying, we get:

ln(P2/101.3 kPa) = -5.631

Taking the exponential of both sides, we get:

P2/101.3 kPa = e^(-5.631)

P2 = 101.3 kPa * e^(-5.631)

P2 = 2.784 kPa

Therefore, the vapor pressure of methanol at 73.5°C is approximately 2.784 kPa, to the first decimal point.

The pH of a solution prepared from 0.201 mol/L of NH4CN and enough water to make 1.00 L of solution is 4.24.

To calculate the pH of this solution, you first need to calculate the concentration of H+ ions in the solution. You can do this by using the following equation:

H+ (mol/L) = [NH4CN]2 x 10-10

Using the given information, the concentration of H+ ions in the solution is:

H+ (mol/L) = [0.201 mol/L]2 x 10-10 = 4.04 x 10-5 mol/L

You can then calculate the pH of the solution using the following equation:

pH = -log10(H+)

Using the concentration of H+ ions, the pH of the solution is:

pH = -log10(4.04 x 10-5) = 4.24

What is Brønsted–Lowry reactions. ?

Brønsted–Lowry reactions are a type of acid-base reaction in which an acid donates a proton (H+) to a base, which then accepts the proton. The Brønsted–Lowry theory defines an acid as a species that donates a proton, while a base is a species that accepts a proton.

In a Brønsted–Lowry acid-base reaction, the acid and base always exist in a conjugate acid-base pair, which are related to each other by the transfer of a proton. For example, in the reaction:

HA + B- → A- + HB

HA is the acid and donates a proton to B-, which is the base. The product A- is the conjugate base of the acid HA, and the product HB is the conjugate acid of the base B-.

Photosystem II receives replacement electrons from molecules of water (H2O) during the light-dependent reactions of photosynthesis.

Photosystem II (PSII) is a protein complex found in the thylakoid membrane of chloroplasts in photosynthetic organisms. It plays a critical role in the light-dependent reactions of photosynthesis by harnessing energy from sunlight to split water molecules into oxygen, protons, and electrons. The replacement electrons for PSII are derived from the oxidation of water molecules. This process, known as photolysis, involves the transfer of electrons from water molecules to PSII, replenishing the electrons lost during light-dependent reactions. As a result, water is converted into oxygen gas, which is released into the atmosphere as a byproduct of photosynthesis.

In summary, molecules of water provide the replacement electrons required by PSII to maintain the flow of electrons during the light-dependent reactions of photosynthesis.

Approximately 5.78 grams of glucose must be consumed to sustain a power output of 25 W for one hour.

Power = Energy/Time

25 W = Energy/3600 s

Energy = 25 W x 3600 s = 90000 J

C6H12O6 + 6O2 → 6CO2 + 6H2O + energy

The energy produced by the complete oxidation of glucose is approximately 2.8 x 10^6 J/mol. Therefore, to produce 90,000 J of energy, we need to divide 90,000 J by the energy produced per mole of glucose:

90,000 J / (2.8 x 10^6 J/mol) = 0.0321 mol

The molar mass of glucose is approximately 180 g/mol. Therefore, the mass of glucose required to sustain a power output of 25 W for one hour is:

0.0321 mol x 180 g/mol = 5.78 g

Power in physics is defined as the rate at which work is done or energy is transferred. It is a scalar quantity that measures how quickly a certain amount of energy is being transferred or converted from one form to another. The standard unit for power is the watt (W), which is equivalent to one joule per second (J/s).

The concentrations of A and B in the reaction after a time of about 75 seconds are 0.0465 M.

The initial concentration of AB is 0.290M. The reaction mixture initially contains no products. The reaction time is 75 seconds, and you need to determine the concentration of A and B. The balanced chemical equation of the reaction is as follows: AB → A + B

According to the law of chemical equilibrium, the concentration of products and reactants changes until a state of equilibrium is reached. As a result, the initial concentration of AB decreases, while that of A and B increases by the same amount. At equilibrium, the rate of the forward reaction is the same as the rate of the backward reaction. As a result, the concentration of the reactants and products remains constant for a long period of time, and the reaction has reached equilibrium. As a result, it is important to identify whether or not the reaction has reached equilibrium. The concentration of A and B is calculated using the following formula:

[A] = C₀ - x

[B] = C₀ - x

[AB] = C₀ - x

Here, x is the amount of the substance that has reacted. Since, we know the initial concentration of AB, we can solve for the value of x. We will then use the value of x to compute the concentrations of A and B. For a reaction, the initial concentration of AB is 0.290M. The reaction mixture initially contains no products. The reaction time is 75 seconds, and you need to determine the concentration of A and B.

The given reaction can be balanced as follows: AB → A + B. Let's assume that at equilibrium, the amount of A and B produced is "x."

[AB] = C-x

Let's calculate the equilibrium concentration of AB:

[AB] = C₀ - x = 0.290 M - x

At equilibrium, the concentrations of A and B are equal since they are produced in equal amounts. Using the law of chemical equilibrium, we can construct the equilibrium constant expression for the reaction:

Kc =x²{0.290 - x}

The equilibrium concentration of AB is 0.290 M - x. The equilibrium concentration of A and B is: x². The equilibrium constant expression can be used to find the value of x. Put the value of [AB], [A], and [B] in the formula of equilibrium constant expression: Kc = x²{0.290 - x}

5.26 = x²{0.290 - x}

{x=0.093}

After solving for x, we get the value of 0.093 M. Therefore, the concentration of A and B at equilibrium is:

[A] = [B] = x{2} = {0.093}{2} = 0.0465

None of the available choices have as many molecules as 1 L of STP-produced C2H4 gas.

At STP (Standard Temperature and Pressure), which is defined as a temperature of 273.15 K and a pressure of 1 atmosphere, the volume of a gas is directly proportional to the number of molecules present. This means that if we have two gases at STP with the same volume, they must contain the same number of molecules.

For a gas with a given volume, the number of molecules present can be calculated using the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

To determine which gas has the same number of molecules as 1 L of C2H4 gas, we need to calculate the number of moles of C2H4 present in 1 L of C2H4 gas. The molar volume of any gas at STP is 22.4 L/mol.

The molar mass of C2H4 is 28.05 g/mol, so 1 L of C2H4 gas at STP contains:

n = m/M = 1000 g / 28.05 g/mol = 35.6 mol

Therefore, 1 L of C2H4 gas contains 35.6 moles of C2H4.

(a) For 0.5 L of H2 gas, the number of moles present is:

n = PV/RT = (1 atm x 0.5 L) / (0.0821 L atm/mol K x 273.15 K) = 0.0207 mol

Since 0.0207 mol is less than 35.6 mol, 0.5 L of H2 gas has fewer molecules than 1 L of C2H4 gas.

(b) For 1 L of Ne gas, the number of moles present is:

n = PV/RT = (1 atm x 1 L) / (0.0821 L atm/mol K x 273.15 K) = 0.0409 mol

Since 0.0409 mol is less than 35.6 mol, 1 L of Ne gas has fewer molecules than 1 L of C2H4 gas.

(c) For 2 L of H2O gas, the number of moles present is:

n = PV/RT = (1 atm x 2 L) / (0.0821 L atm/mol K x 273.15 K) = 0.082 mol

Since 0.082 mol is less than 35.6 mol, 2 L of H2O gas has fewer molecules than 1 L of C2H4 gas.

(d) For 3 L of Cl2 gas, the number of moles present is:

n = PV/RT = (1 atm x 3 L) / (0.0821 L atm/mol K x 273.15 K) = 0.123 mol

Since 0.123 mol is less than 35.6 mol, 3 L of Cl2 gas has fewer molecules than 1 L of C2H4 gas.

The final concentration of Sodium Azide in the locomotion chambers will be 10mM (millimolar) if 10mL (milliliters) of the Chlamydomonas, 100 μL (microliters) of sterile water, and 100 μL of 1M (molar) Sodium Azide is added.

The final concentration of DCMU (3-(3,4-dichlorophenyl)-1,1-dimethylurea) in the locomotion chambers will be 0.1 mM (millimolar) if 10 mL (milliliters) of the Chlamydomonas, 100 μL (microliters) of sterile water, and 100 μL of 10 mM (millimolar) DCMU are added.

Calculating the final concentration of DCMU:

Formula: C1V1 = C2V2C1 = initial concentration of DCMU = 10 mMV1 = volume of DCMU added = 100 μL (microliters)C2 = final concentration of DCMU = ?V2 = final volume = 10 mL + 100 μL + 100 μL = 10.2 mL

(convert 100 μL to mL by dividing it by 1000)

Substituting the values in the formula:

C1V1 = C2V210 mM x 100 μL = C2 x 10.2 mL1000 (since 1 mL = 1000 μL)C2 = 0.098 mM (millimolar) = 0.1 mM (approx.)

Thus, the final concentration of DCMU in the locomotion chambers will be 0.1 mM if 10mL of the Chlamydomonas, 100 microliters of sterile water, and 100 microliters of 10mM DCMU is added.

A student makes three plots of their data and finds that a plot of [A] vs t is linear, a plot of ln[A] vs t is non-linear, and a plot of 1/[A] vs t is non-linear. The rate law of the reaction is b. Rate = k[A]

The given question is related to the rate law of the reaction. The student makes three plots of their data and finds that a plot of [A] vs t is linear, a plot of ln[A] vs t is non-linear, and a plot of 1/[A] vs t is non-linear. The rate law of a reaction is a mathematical equation that relates the rate of the reaction to the concentrations of reactants and the reaction's constant of proportionality. The rate law is also called the rate equation or rate expression.

As per the given information, the plot of [A] vs t is linear, which means that the reaction is a first-order reaction. The plot of ln[A] vs t is non-linear, which means that the reaction is not zero-order or first-order. It could be a second-order or third-order reaction. The plot of 1/[A] vs t is non-linear, which means that the reaction is not a first-order reaction. It could be a second-order or third-order reaction. Therefore, the rate law of the reaction can be given as Rate = k[A]. This represents a first-order reaction. Hence, the correct option is Rate = k[A].
