Problem: When a mixture of 13.0 g of acetylene (C2H2) and 13.0 g of oxygen (O2) is ignited, the resultant combustion reaction produces CO2 and H2O.How many grams of CO2 are present after the reaction is complete?

FREE Expert Solution

We’re being asked to calculate the mass of CO2 that will be formed in the reaction.


For this problem, we need to do the following steps:

Step 1: Write and balance a chemical equation for the given reaction.

Step 2: Determine the limiting reactant and calculate the mass of CO2 formed.



Step 1: We can write the combustion reaction of acetylene as follows:

C2H2 + O2 → CO2 + H2O


This equation is not yet balanced. To balance it, we have to make sure that the number of elements on both sides is equal.
