Propane is often used in stoves and cooktops as a source of heat. The combustion of propane yields water and carbon
1 answer:
Answer: 3 molecules of carbon dioxide and 4 molecules of water are produced during the combustion of propane.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction for combustion of propane is:
3 molecules of carbon dioxide and 4 molecules of water are produced during the combustion of propane.

In this case, for this stoichiometry-based problem, it is firstly necessary to realize that the decomposition of ammonium dichromate is given by:
Thus, since the mole ratio between ammonium dichromate and the gaseous nitrogen (molar mass = 28.02 g/mol) is 1:1, we can compute the produced mass of the latter via stoichiometry as shown below:
