Answer:

Given rate constant of the first-order reaction is:

K=7.30x10^-4 s-1

Time t=500s

Determine % H2O2 decomposed in first 500 s in a first-order decomposition reaction of H2O2?

Explanation:

The expression for the rate constant of the first-order reaction is:

[tex]k=\frac{2.303}{t} log \frac{ao}{a-x}[/tex]

where,

k=rate constant

t=time period

ao=initial amount of the reactant

a-x=amount of a remained after time t.

Substitute the given values in the above formula to get ao/a-x value.

[tex]7.30x10^-4 s^-1 = \frac{2.303}{500s} log \frac{ao}{a-x} \\log \frac{ao}{a-x} =7.30x10^-4 s^-1 * \frac{500s}{2.303} \\log \frac{ao}{a-x} =0.158\\\frac{ao}{a-x}=10^{0.158} \\\frac{ao}{a-x}=1.438[/tex]

% of H2O2 decomposed is:

[tex]\frac{ao}{a-x} = 1.438 *100\\ =143.8[/tex]

Answer: The author used the word "conversely" because the first statement he made is in CONTRAST to the second statement he made.

Explanation:

Matter is made up of atoms or molecules that are in constant motion. The motion of these tiny particles ( molecules) gives the object energy. The movement of these molecules depends on the state of matter which includes

--> GASEOUS STATE: Here, the particles are completely free to move and are always in motion.

--> LIQUID STATE: particles in this state slide by one another and are always in motion.

--> SOLID STATE: particles in this state are held tightly together but are always in motion.

Also, the molecules in motion are greatly affected by temperature changes. Increase in temperature will cause the particles in the liquid to move faster. Such is seen when soup is heated, the molecules travel faster than before. But the OPPOSITE is seen in an ice cube. This is because the ice cube is in solid state and of a lower temperature.

Answer:

a. 0.8 moles of CO₂ are produced when 0.400 mol of C₆H₁₂O₆ reacts.

b. 7.5 grams of C₂H₅OH are produced by 14.67 grams of C₆H₁₂O₆.

c. 7.17 grams of CO₂ form when 7.50 g of C₂H₅OH are produced.

Explanation:

The balanced reaction is:

C₆H₁₂O₆  → 2 C₂H₅OH + 2 CO₂

By reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:

The molar mass of each compound is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Then you can apply the following rules of three:

a. If 1 mole of C₆H₁₂O₆ produces 2 moles of CO₂, 0.4 moles of C₆H₁₂O₆ produces how many moles of CO₂?

[tex]moles of CO_{2} =\frac{0.4 moles of C_{6} H_{12} O_{6} *2moles of CO_{2} }{1 mole of C_{6} H_{12} O_{6} }[/tex]

moles of CO₂= 0.8 moles

0.8 moles of CO₂ are produced when 0.400 mol of C₆H₁₂O₆ reacts.

b. If 92 grams of C₂H₅OH are produced by 180 grams of C₆H₁₂O₆, 7.5 grams of C₂H₅OH are produced by how many mass of C₆H₁₂O₆?

[tex]mass of C_{6} H_{12} O_{6}=\frac{7.5 grams of C_{2} H_{5} OH* 180 grams of C_{6} H_{12} O_{6}}{92grams of C_{2} H_{5} OH}[/tex]

mass of C₆H₁₂O₆= 14.67 grams

7.5 grams of C₂H₅OH are produced by 14.67 grams of C₆H₁₂O₆.

c. If 92 grams of C₂H₅OH are produced along with 88 grams of CO₂, 7.5 grams of C₂H₅OH are produced along with how many mass of CO₂?

[tex]mass of CO_{2}=\frac{7.5 grams of C_{2} H_{5} OH* 88 grams of C O_{2}}{92grams of C_{2} H_{5} OH}[/tex]

mass of CO₂= 7.17 grams

7.17 grams of CO₂ form when 7.50 g of C₂H₅OH are produced.

Answer:

SiO2

Explanation:

Answer:

Most oxidation-reduction (redox) processes involve the transfer of oxygen atoms, hydrogen atoms, or electrons, with all three processes sharing two important characteristics: (1) they are coupled—i.e., in any oxidation reaction a reciprocal reduction occurs, and (2) they involve a characteristic net chemical change— .

Electrons will be transferred during redox reaction.

The electron is subatomic particles which are placed in surrounding the nucleus. Electrons carry negative charge.

Redox reaction involve the transfer of electrons between intermediates. A redox reaction occurs when the oxidation states of the substrate change. The removal of electrons or even a rise in the oxidation state of such a chemical or its atoms is referred to as oxidation. The acquisition of electrons or a lowering in the oxidation number of a chemical or the atoms inside it is referred to as reduction.

Hence the answer will be electron

Answer:

449.7 kPa

Explanation:

We prepare the Ideal Gases Law to solve this question:

P . V = n . R . T

As moles of gas are the same, and R is constant, we can compare this two situations:

P₁ . V₁ / T₁  and P₂ . V₂ / T₂

As this remains constant we can propose:

P₁ . V₁ / T₁  = P₂ . V₂ / T₂

We convert T° to Absolute value: 30°C + 273 = 303 K

We convert the volume from mL to L

800 mL . 1L /1000 mL = 0.8 L

200 mL . 1L /1000 mL = 0.2 L

1 atm . 0.8 L / 273 K = P₂ . 0.2L / 303k

(0.8 L.atm / 273K ) . 303k = P₂ . 0.2L

0.8879 L.atm / 0.2L = 4.4 atm

We convert pressure from atm to kPa

4.4 atm . 101.3 kPa / 1 atm = 449.7 kPa

Answer:

450. kPa

Explanation:

Use the combined gas law. Solve for the unknown. Plug in the numbers, turn the crank, and out pops the answer. A typical plug-n-chug problem.

P1V1 / T1 = P2V2 / T2 …………….. combined gas law

P2 = P1V1T2 / (T1V2) ……………… solve for P2

P2 = 101.3 kPa x 800. mL x 303K / 273K / 200. mL

P2 = 450. kPa

We are assuming 3 significant digits, simply because it makes more sense than having only one significant digit. You didn’t actually specify a pressure unit, but I’m guessing you mean kilopascal, (kPa).

19.5g is the theoretical yield of alum

Explanation:

Based on the balanced reaction, 4 moles of sulfuric acid produce 2 moles of alum. To solve this question we need to find the moles of H2SO4. With these moles we can find the moles of alum and its mass assuming all sulfuric acid reacts producing alum.

Moles Sulfuric Acid:

8.3mL = 0.0083L * (9.9mol/L) = 0.08217 moles sulfuric acid

 Upwelling is caused by the winds that on the oceans surface is the correct answer.

Ocean currents are water flow patterns that have an impact on climate zones and weather patterns all around the globe.

When winds blow they push the water from an area and to replace the displaced water water rises from beneath the surface and this process is called Upwelling.

answer:Collisions between gas particlCollisions between gas particles or collisions with the vessel walls are perfectly elastic.

explanation:As long as an ideal gas is maintained at a constant temperature, the average kinetic energy of the molecules is said to be constant. In fact, what we call the temperature of a body at the macroscopic scale is just a representation of the kinetic energy carried by its atoms or molecules as they vibrate inside the body.

Now, if the kinetic energy of this oxygen gas is constant, it is because the collisions between the particles are assumed to be perfectly elastic. No energy is lost during the collisions. The rationale behind this assumption is that the particles are very tiny.

The answer which corresponds best to the explanation above is b. Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.

The black solid is magnetic due to the special property of iron called ferromagnetism

6.9 g

Explanation:

The substance FeS is magnetic despite of the fact Fe^2+ is spin paired due to the special magnetic property of iron called ferromagnetism.

The equation of the reaction is;

Fe(s) + S(s) ----> FeS(s)

Number of moles of Fe = 5g/56g/mol = 0.089 moles

Since the reaction is 1:1, 0.089 moles of FeS is formed

For Sulphur;

Number of moles of sulphur = 2.5g/32 g/mol = 0.078 moles

Since the reaction is 1:1, 0.078 moles of FeS is formed

Hence sulphur is the limiting reactant.

So, mass of FeS produced = 0.078 × 87.91 g/mol = 6.9 g

Answer:

24 N

Explanation:

Mechanical advantage is the rate of load overcome to the effort applied to overcome the load or resistance. Also, it is the quotient of the resistance force to the effort force.

i.e MA = [tex]\frac{L}{E}[/tex]

Given that, MA = 4, and L = 6.0 N, then;

4 = [tex]\frac{L}{6}[/tex]

cross multiply to have

L = 4 x 6

  = 24 N

L = 24 N

Thus, the force exerted on the resistance by the machine is 24 N.
