Question

Classify the following reaction:

H₂CO₃(aq) → H₂O(l) + CO₂(g)

A) synthesis (or combination)
B) decomposition
C) combustion
D) single displacement (replacement)
E) double displacement (replacement)

Answer 1

Decomposition

Step-by-step explanation:

Those reactions where one reactant gets broken or decomposed into two or more products that reaction is called decomposition reaction.

Now

here H2CO3 is decomposed into H2O and CO2

Answer 2

Answer :-

H2CO3( AQ) gives H2O + CO2

This reaction is decomposition reaction

Decomposition reaction are those reactions in which reactant is breakdown in a form that it gives two or more than two products

All decomposition reaction are endothermic but all endothermic reactions are not decomposition reaction .

Hence, Option B is the correct answer.
