How many chemical reactions are possible regarding the formation of carbonic acid and the dissolving of calcite?
A. 3
B. 23
C. 2
D. 10
I think its A.??
To determine the correct answer, let's break down the possible chemical reactions for the formation of carbonic acid and the dissolving of calcite:
The formation of carbonic acid can be represented by the following reaction:
CO2 + H2O -> H2CO3
Meanwhile, the dissolving of calcite (CaCO3) can be represented by the following reaction:
CaCO3 + H2O + CO2 -> Ca(HCO3)2
Therefore, the total number of chemical reactions possible, combining these two reactions, would be 2.
The correct answer is C. 2.
To determine the number of chemical reactions possible regarding the formation of carbonic acid and the dissolving of calcite, you would need to understand the chemical equations involved.
Carbonic acid (H2CO3) is formed by the reaction between carbon dioxide (CO2) and water (H2O):
CO2 + H2O → H2CO3
Calcite (CaCO3) dissolves in water through a reaction called carbonation:
CaCO3 + H2O + CO2 → Ca2+ + 2HCO3-
By analyzing these equations, we can see that there are two possible chemical reactions involved: the formation of carbonic acid and the dissolving of calcite.
Therefore, the correct answer is C. 2.
