Question

What type of reaction is this? CaCO3 + H2SO4 → CaSO4 + H2O + CO2. A) Synthesis B) decomposition C) combustion

Answer 1

B) decomposition

Step-by-step explanation:

In a decomposition reaction a complex reactant breaks down into simple molecules. Here the carbonate is decomposing into carbon dioxide. in a synthesis reaction two elements combine to form a complex product. In a combustion reaction a hydrocarbon burns in the presence of oxygen to form carbon dioxide and water.

Answer 2

The correct answer to this question is letter "B. decomposition." The type of reaction in the chemical reaction is decomposition.

CaCO3 + H2SO4 → CaSO4 + H2O + CO2
Looking at the equation, it shows decomposition.
