C3H8 + xO2 > 3CO2 + yH2O which value of x and y balance the equations

Chemistry
1 answer:
Gelneren [198K]3 years ago
8 0

Answer:

x = 5 and y =4

Explanation:

An alkane is a hydrocarbon of general molecular formula CnH2n+2. The general formula for balancing the combustion equation of any alkane is;

CnH2n+2 + 3n+1/2O2 ------> nCO2 + (n+1) H2O

Where n is the number of carbon atoms in the alkane.

In C3H8 , n=3 so;

C3H2(3)+2 + 3(3)+1/2O2 ------> 3CO2 + (3+1) H2O

Then;

C3H8 + 5O2  ------> 3CO2 + 4H2O

Therefore;

x = 5 and y =4
