Problem: Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water. Suppose 6.9 g of octane is mixed with 11.8 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.

FREE Expert Solution

Determine the balanced equation and apply stoichiometry to determine the leftover mass of octane after the reaction

Before balancing the chemical reaction, let’s first write the chemical formula of each of the compounds involved in the reaction.

Reactants:

Octane (liquid)

▪ Octane is hydrocarbon with a general formula of CnH2n+2

▪ the prefix oct- means that the hydrocarbon has 8 carbons

Octane: C8H2(8)+1

Octane: C8H18(l)

Oxygen (gas)

▪ oxygen gas is the natural state of oxygen

▪ natural state of oxygen →O2(g)

Products:

Carbon dioxide (gas) CO2(g)

Water vapor (gas) →H2O(g)
