d. H2O: 3 .
The balanced chemical equation for the incomplete combustion of ethane. The incomplete combustion of ethane produces carbon monoxide, water vapor, and heat.
The balanced chemical equation is as follows:
C2H6 + 2O2 → 2CO + 3H2O
Looking at the reactants in the balanced chemical equation, we see that we need 1 molecule of ethane and 2 molecules of oxygen to produce 2 molecules of carbon monoxide and 3 molecules of water vapor.
Therefore, to answer the question, we need to count the number of particles of each type in the reactants.
C2H6: There is 1 molecule of ethane in the reactants.
O2: There are 3 molecules of oxygen in the reactants.
CO: There are 2 molecules of carbon monoxide in the products.
H2O: There are 3 molecules of water vapor in the products.
Therefore, the following number of particles of each type should have been present in the reactants:
C2H6: 1
O2: 3
CO: 2
H2O: 3 .
