Question

The bubbles that make a baked cake light and tender come from the decomposition of carbonic acid (H2CO3) in the cake batter.

Which are the likely products of this reaction?


H2, O2, and C

H2O, O2, and C

CO2 and H2O

CO2 and H2

Answer 1

I believe that carbonic acid breaks down into carbon dioxide and water when under decomposition.

The answer should be CO2 and H2O

Answer 2

Answer:
`CO_2` and
`H_2O`

Explanation:

Decomposition reaction is a type of chemical reaction in which one reactant gives two or more than two products.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

`H_2CO_3\rightarrow H_2O+CO_2`
