Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 97. g of octane is mi
zhannawk [14.2K]

Answer: 61 grams

Explanation:

To calculate the number of moles, we use the equation:

\text{Number of moles of octane}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{97g}{114g/mol}=0.85moles

\text{Number of moles of oxygen}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{150g}{32g/mol}=4.69moles

The chemical equation for the combustion of octane in oxygen follows the equation:

2C_8H_{18}+25O_2\rightarrow 16CO_2+18H_2O

By stoichiometry of the reaction;

25 moles of oxygen react with 2 moles of octane

4.69 moles of oxygen react with=\frac{2}{25}\times 4.69=0.37  moles of octane

Thus, oxygen is the limiting reagent as it limits the formation of product and octane is the excess reagent.

25 moles of oxygen produce 18 moles of water

4.69 moles of oxygen produce=\frac{18}{25}\times 4.69=3.38  moles of water.

Mass of water produced=moles\times {\text{Molar mass}}=3.38\times 18g/mol=61g

The maximum mass of water that could be produced by the chemical reaction is 61 grams.

Ierofanga [76]

Answer:

The new volume will be

0.7 L

Explanation:

This is an example of Charles' law, sometimes called the temperature-volume law. It states that the volume of a gas is directly proportional to the Kelvin temperature, while pressure and amount are held constant.
