Question

Identify the correct coefificients to balance it
-C3H8+O2 to -CO2 +-H2O

Answer 1

.

Step-by-step explanation:

.

Among the four species in this reaction,
is species with the largest number of atoms per molecule. Assume that the coefficient of this compound is
.

.

Number of atoms on the left-hand side of the reaction:

• 
  :
  .
• 
  :
  .
• 
  : not found yet.

By the conservation of atoms, the number of atoms on the right-hand side of the reaction should match those on the left-hand side. In this reaction,
is the only product with carbon atoms, whereas
is the only product with hydrogen atoms. These
carbon atoms and
hydrogen atoms would correspond to:

• 
  
  molecules, and
• 
  
  molecules.

Number of atoms on the right-hand side of the reaction:

• 
  :
  .
• 
  :
  .
• 
  :
  .

The number of
atoms on the left-hand side should match those on the right-hand side. In this reaction,
is the only reactant with
atoms. These

atoms would correspond to:

• 
  
  molecules.
