Answer:

if 12 moles are produced then it came 24 moles of Al(OH)3

Explanation:

The number that is written in front of the molecule is called stoichiometry, represents the number of mole of that molecule. 12 moles of [tex]Al_{2}O__{3}[/tex] is produced by 24 mole of Aluminum.

Stoichiometry is a part of chemistry that help us in making relationship between reactant and product from quantitative aspects. It tells about how much part of reactant will be required to produce particular product. Unitary method is always applied in case of stoichiometry chemistry.

The balanced equation is

[tex]4Al+3O_{2}\rightarrow 2Al_{2}O__{3}[/tex]

The mole ratio between  [tex]Al_{2}O__{3}[/tex] and Al is 2:4, means to produce 4 moles of [tex]Al_{2}O__{3}[/tex] we need 2 moles of Aluminum

4 mole of [tex]Al_{2}O__{3}[/tex]= 2 moles of Aluminum

1 mole of [tex]Al_{2}O__{3}[/tex]=(1÷2) moles of Aluminum

12 moles of [tex]Al_{2}O__{3}[/tex]= 24 mole of Aluminum

Therefore 12 moles of [tex]Al_{2}O__{3}[/tex] is produced by 24 mole of Aluminum.

Answer:

pOH = 9.

Explanation:

The inverse relationship between the pH and pOH of any given solution can be written as:

pH = 14 - pOH

Or conversely:

pOH = 14 - pH

With the above information in mind we can use the given pH to calculate the pOH:

pOH = 14 - pH

pOH = 14 - 5

pOH = 9

Thus, black coffee has a pOH of 9.

Answer:

48 grams

Explanation:

The chemical equation for the reaction is the following:

2 H₂ + O₂ → 2 H₂O

That means that 2 moles of H₂ react with 1 mol of O₂ to produce 2 moles of H₂O. We convert the moles of oxygen (O₂) by using the molecular weight (MW) as follows:

MW(O₂) = 16 g/mol x 2 = 32 g/mol

mass of O₂ = 1 mol x 32 g/mol = 32 g

So, we have the following stoichiometric ratio: 32 g O₂/2 moles H₂. We have 3 moles of hydrogen (H₂), so we multiply the moles by the stoichiometric ratio to calculate how many grams are needed:

3 moles H₂ x 32 g O₂/2 moles H₂ = 48 g O₂

Therefore, 48 grams of O₂ are needed to react with 3 moles of H₂.

Answer:

If there are fewer births than deaths, then the size of the population will decrease. Organisms in consumer populations get energy storage molecules from eating organisms in resource populations. The more energy storage molecules available to a population, the more the organisms in that population can reproduce.

A change to the green-leaf population caused the wee-bug population to change in size because wee-bug depends upon green leaves for their food.

It is a group of organism of the same species living in a particular area.

The increase or decrease in the population of organisms depends upon factors such as available resources and predator population.

The green leaf is the food resource for wee bugs hence if the green leaf population increase then the wee bug's population will also be increased.

Therefore, a change to the green-leaf population caused the wee-bug population to change in size because wee-bug depends upon green leaves for their food.

Answer:

2.040 mol CO

Explanation:

First, write out your reaction:

CO + O2 --> CO2

Balance the reaction:

2CO + O2 --> 2CO2

Now divide the 32.65 g O2 by the molar mass of O2 (32.00 g/mol) to get moles of O2. Then multiply by the mole ratio of 2 mol CO for every 1 mol O2 to get moles of CO needed to fully react.

32.65 g O2 / 32.00 g/mol = 1.020 mol O2

1.020 mol O2 • 2 mol CO / 1 mol O2 = 2.040 mol CO

Answer:

4.20L/321.2K=x/288.4K

multiply both side by 288.4

1211.28/321.2=x

x=3.77L

Option 3 13.15 is the  correct answer.

Charles's law exists as an experimental gas law that explains how gases tend to expand when heated. A modern statement of Charles's law exists: When the pressure on a sample of a dry gas exists held constant, the Kelvin temperature and the volume will be in direct proportion.

According to Charles law

The volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.

[tex]V1/T1=V2/T2[/tex]

Where,

[tex]V1[/tex]= first volume

[tex]V{2}[/tex] = second volume

[tex]T{1}[/tex] = first temperature

[tex]T{2}[/tex]= second temperature

Here, at constant pressure,

[tex]V1/T1=V2/T2[/tex]

[tex]V1[/tex]=4.20 L

[tex]V2[/tex]= x

[tex]T1[/tex]=321.2 K

[tex]T2[/tex]=288.4 K

Therefore, [tex]V1/T1=V2/T2[/tex]

4.20L/321.2K=x/288.4K

1211.28/321.2=x

x=3.77L

Thus option a is correct.

Answer:

The volume will be 568.89 mL.

Explanation:

Boyle's law says that "The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"

Boyle's law is expressed mathematically as:

Pressure * Volume = constant

or P * V = k

Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. That is, the pressure of the gas is directly proportional to its temperature. Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T}=k[/tex]

Where P = pressure, T = temperature, K = Constant

Finally, Charles's law indicates that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T}=k[/tex]

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

[tex]\frac{P*V}{T} =k[/tex]

Studying an initial state 1 and a final state 2, it is fulfilled:

[tex]\frac{P1*V1}{T1} =\frac{P2*V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{960 mmHg*550 mL}{473K} =\frac{830 mmHg*V2}{423 K}[/tex]

Solving:

[tex]V2=\frac{423 K}{830 mmHg} *\frac{960 mmHg*550 mL}{473K}[/tex]

V2= 568.9 mL

The volume will be 568.89 mL.
