Answer:
No.
Explanation:
Photosynthesis is the light dependent process which must occur for the plant to live. This process also requires water and carbon dioxide. If photosynthesis does not occur, the plant will die.
If plants do not receive enough water from the water cycle, photosynthesis can be affected, and in severe cases, it may not take place at all.
Why photosynthesis requires water?Photosynthesis requires water as one of its essential inputs, as it is used in the process of creating glucose and oxygen from carbon dioxide and light energy. Therefore, if plants do not receive enough water from the water cycle, photosynthesis can be impacted, and in severe cases, it may not take place at all.
Water is not only a raw material in photosynthesis, but it is also necessary for the regulation of plant cells' internal pressure, which is essential for maintaining their shape and structure. Without enough water, the cells' internal pressure decreases, causing them to shrink and lose their rigidity. This process is known as wilting.
Hence, water is essential for plant growth and photosynthesis, and if plants do not receive enough water from the water cycle, it can lead to wilting, stunted growth, and a reduction in photosynthesis.

A)220Fr and 60C0
B)37K and 42K
C)37Ca and 53Fe
D)99Tc and 19Ne
Answer:
c
Explanation:
37Ca and 53Fe have the same decay mode.
What are the three common modes of radioactive decay?Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles.
Which isotopes are most likely to decay?The most likely mode of decay for a neutron-rich nucleus is one that converts a neutron into a proton. Every neutron-rich radioactive isotope with an atomic number smaller than 83 decays by electron emission. C, 32P, and 35S, for example, are all neutron-rich nuclei that decay by the emission of an electron.

How many calories of heat were added to 167.9 g of water to raise its temperature from 25oC to 55oC?
Answer:
Q = 5036.9 calories
Explanation:
Given that,
Mass, m = 167.9 g
The temperature raises from 25°C to 55°C.
The specific heat of water,c = 4.184 J/g °C
We need to find the heat added to water. We know that,
[tex]Q=mc\Delta T\\\\=167.9 \times 4.184\times (55-25)\\\\=21074.8\ J[/tex]
or
Q = 5036.9 calories
So, 5036.9 calories of heat is added.

Suppose that the student took one more volume
reading of 24.2 mL but forgot to measure the
pressure.
Compute the pressure expected for that
volume. kg/cm2?
Answer:
2.13 Kg/cm².
Explanation:
We'll begin by calculating the constant that exist between the pressure and the volume. This can be obtained by using the Boyle's law equation as shown below.
Boyle's law states that
PV = K
Where
P is the pressure.
V is the volume.
K is the constant.
We shall determine the value of K as follow:
Pressure (P) = 1.15 Kg/cm²
Volume (V) = 44.8 mL
Constant (K) =?
PV = K
1.15 × 44.8 = K
K = 51.52 Kg/cm²•mL
Finally, we shall determine pressure, when the volume is 24.2 mL. This can be obtained as follow:
Volume (V) = 24.2 mL
Constant (K) = 51.52 Kg/cm²•mL
Pressure (P) =?
PV = K
P × 24.2 = 51.52
Divide both side by 24.2
P = 51.52 / 24.2
P = 2.13 Kg/cm²
Therefore, the pressure is 2.13 Kg/cm².

What is the molarity of a 511 ml solution containing

401M 0.0235M 0.401M 0.0000235M
What is the amount of moles of NaOH, if the solution molarity is .33 M NaOH in 0.75 L solution
Answer:
The amount of moles of NaOH is 0.0495
Explanation:
Molarity is a measure of concentration that is defined as the number of moles of solute that are dissolved in a given volume.
In symbolic form molarity is presented as:
[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case:
Molarity= 0.33 MNumber of moles of solute= ?Volume= 0.75 LReplacing in the definition of molarity:
[tex]0.33 M=\frac{number of moles of solute}{0.75 L}[/tex]
number of moles of solute= 0.33 M* 0.75 L
number of moles of solute= 0.0495 moles
The amount of moles of NaOH is 0.0495
Answer:
0.248 moles of NaOH
Explanation:
Concept of Molarity is mol/L
[x] = 1 M
1 mol of x contained in 1 L of solution. We write molar concentrations between []
M = mol/L then M . L = mol
Our solution is NaOH
0.33 M . 0.75L = mol
This solution contains 0.248 moles of NaOH

When calcium carbonate is heated strongly, carbon dioxide gas is evolved. CaCO3(s) → CaO(s) + CO2 (g) If 4.74 g of calcium carbonate is heated, what volume of CO2 (g) would be produced when collected at STP?
Answer:
1.06 liters of gas are produced
Explanation:
Our reaction is:
CaCO₃(s) → CaO(s) + CO₂ (g)
This is the decomposition of calcium carbonate.
Ratio is 1:1:1
1 mol of carbonate can decompose to 1 mol of oxide and 1 mol of oxygen.
We convert mass to moles:
4.74 g . 1 mol /100.08g = 0.0474 moles
These are the moles of oxygen produced.
We know that 1 mol of any gas at STP is contained in 22.4L
0.0474 mol . 22.4L /mol = 1.06 L

A solution is 5.00% by volume of ethanol dissolved in water. How many mL of ethanol are in 500 mL of the solution?
Answer:
[tex]v_{solute}=25mL[/tex]
Explanation:
Hello there!
In this case, according to the by-volume concentration of this solution, it is possible for us to use its mathematical definition as shown below:
[tex]\%v=\frac{v_{solute}}{v_{solution}}*100\%[/tex]
Thus, given the percent and the volume of the solution, we can solve for the volume of ethanol (solute) as shown below:
[tex]v_{solute}=\frac{\%v*v_{solution}}{100\% }\\\\v_{solute}=\frac{5.00\%*500mL}{100\%}\\\\ v_{solute}=25mL[/tex]

A gas of certain mass occupies volume of 1.2 L at 37°C and 3 atm. At what temperature will the volume and pressure of this gas become one-third of their initial values?
Answer: At a temperature of 34.44 K the volume and pressure of this gas become one-third of their initial values.
Explanation:
Given : [tex]V_{1}[/tex] = 1.2 L, [tex]T_{1} = 37^{o}C = (37 + 273) K = 310 K[/tex]
[tex]P_{1}[/tex] = 3 atm, [tex]V_{2} = \frac{1.2}{3} = 0.4 L[/tex] , [tex]P_{2} = \frac{3}{3} = 1 atm[/tex]
Formula used to calculate the final temperature is as follows.
[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]
Substitute the values into above formula as follows.
[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{3 atm \times 1.2 L}{310 K} = \frac{1 atm \times 0.4 L}{T_{2}}\\T_{2} = \frac{1 atm \times 0.4 L \times 310 K}{3 atm \times 1.2 L}\\= \frac{124}{3.6} K\\= 34.44 K[/tex]
Thus, we can conclude that the final temperature is 34.44 K.

A sample of gas is inside of a rigid container with fixed volume of 350mL. The initial pressure of the system is 366kPa, and the initial temperature is 88 degrees Celsius. How would the pressure of the system change if the temperature was increased to 110 degrees Celsius?
Answer:
457.5kPa
Explanation:
Given data
V1=V2=350mL (fixed volume )
P1=366kPa
T1= 88 degrees Celsius
P2=??
T2= 110 degrees Celsius
For the general gas equation
P1V1/T1= P2V2/T2
V1=V2
P1/T1= P2/T2
Substitute
366/88= P2/110
Cross multiply we have
P2*88=366*110
P2*88= 40260
P2= 40260/88
P2= 457.5 kPa
Hence the pressure will change to 457.5kPa

What reactants form a combustion reaction?
Answer:
Hydrocarbon and oxygen
Explanation:
"a substance reacts with oxygen gas, it must involve O² as one of the reactants."
Using this, we can confirm Hydrocarbon and oxygen is a valid one.
1. Make a claim that answers the following question: "What is the
connection between the number of valence electrons and
chemical/physical properties?" *
Lets take an example to explain this
Sodium(Na) has 1 electron in its outer or valence shell hence it will lose it and become a cation say to Chlorine(Cl)
To form Sodium Chloride.
Since it is capable of losing electrons, Sodium becoems a metal and has properties of metal
Whereas Chlorine which has 7 electrons in its valence shell gains an electrons to become an anion
Hence it is a non metal
And has the properties of an anion
how much heat is required to increase the temperature of 20 grams of water by 26 degrees celsius?
Answer: 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.
Explanation:
Given: Mass = 20 g
Change in temperature = [tex]26^{o}C[/tex]
The standard value of specific heat of water is [tex]4.184 J/ g^{o}C[/tex]
Formula used to calculate the heat energy is as follows.
[tex]q = m \times C \times \Delta T[/tex]
where,
q = heat energy
m = mass of substance
C = specific heat of substance
[tex]\Delta T[/tex] = change in temperature
Substitute the values into above formula as follows.
[tex]q = m \times C \times \Delta T\\= 20 g \times 4.184 J/g ^{o}C \times 26^{o}C\\= 2175.68 J[/tex]
Thus, we can conclude that 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.
