Question

How many molecules of each substance are present after the combustion of 3 molecules of propane with 10 molecules of oxygen?

Answer 1

Answer:

Thus, three CO2 molecules are formed for every C3H8 molecule consumed. ... To balance the 10 oxygen atoms in the products of this reaction we need five O2 molecules among the reactants. 1 C3H8 + 5 O2 3 CO2 + 4 H2O. There are now three carbon atoms, eight hydrogen atoms, and 10 oxygen atoms on each side of the equation.
