Question

consider the following reaction: aC6H6 + bO2 —> cCO2 + dH2O. on balancing , the ratio b:c is ??​

Answer 1

On reactant side, On product side,

C=6 C=1

O=2 O=3

H=6 H=2

So, to balance this equation.we have to make the Reactant=Product

,So. 2C6H6 + 15 O2 ---------> 12CO2 + 6H2O

Answer 2

The ratio of b:c is 5:4.

• Benzene reacts with oxygen gas to form carbon dioxide gas along with water.
• Hence the balanced reaction is as follows-
• $2C_6H_6+15O_2\rightarrow 12CO_2+6H_2O$.
• In this reaction, two moles of Benzene react with 15 moles of oxygen gas to form 12 moles of carbon dioxide gas along with six moles of water.
• The value of b is 15 and the value of c is 12.
• Hence the value of b:c is 15:12 or 5:4.
