Question

13. Why are decomposition reactions called the opposite of combination reactions?
Write equations for these reactions.​

Answer 1

Answer:

As in decomposition reaction one compound decompose to various different different products whereas in combination reaction two or more compounds or elements combine to form single product

Eg:

a)H2+O2gives H2O

b)H2Oby action of electricity gives H2 +O2

Answer 2

Explanation:

Decomposition Reaction: Reaction in which a single reactant break down into two or more products.

Equation: C + O2. ---> CO2

Combination Reaction: Reaction in which two or more reactants combine to form one product.

Equation: CO2 ---> C + O2

So, decomposition reaction is opposite of combination reaction.
