When carbonate minerals come into contact with hydrochloric acid they
2 answers:
Answer:
Fizz
Explanation:
The bubble of carbon dioxide that you observe are the evidence of occurrence of chemical reaction.
When this reaction occurs, there is a presence of minerals of calcite or carbonate. Few other minerals of carbonates react with hydro chloric acid. Each of these minerals which consists of one or grater than one ion of metal which are combined with a ion of carbonate that is ().
Fizz is occur when there is a reaction between carbonate minerals and hydrochloric acid.

Explanation:
Given decomposition reaction:
- 1PCl₅ (g) ⇄ 1PCl₃ + 1Cl₂(g)
Equilibrium constant:
Stoichiometric coefficients and powers equal to 1 are not usually shown as they are understood, but I included them in order to shwow you how they intervene in the equilibrium expressions: each concentration is raised to a power equal to the respective stoichiometric coefficient in the equilibrium equation.
So, your calculations are:
