<u>Answer:</u>
<u>For a:</u> The balanced chemical equation is given below.
<u>For b:</u> The mass of carbon dioxide produced will be
<u>Explanation:</u>
- <u>For a:</u>
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor can be destroyed but it can only be transformed from one form to another form.
This law also states that the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
For the given reaction, the balance chemical equation follows:
All the substances are present in gaseous state.
- <u>For b:</u>
By Stoichiometry of the reaction:
1 mole of propane gas produces 3 moles of carbon dioxide gas.
So, 8.11 moles of propane gas will produce = of carbon dioxide gas.
Now, calculating the mass of carbon dioxide using equation:
Molar mass of carbon dioxide = 44 g/mol
Moles of carbon dioxide = 24.33 mol
Putting values in above equation, we get:
Hence, the amount of produced in the given reaction and expressed in scientific notation is
