What is the chemical formula acid?

Answer 1

Answer

Limestone is largely composed of calcium carbonate, also known as CaCO3.

This can become quicklime (Calcium Oxide) and carbon dioxide from high levels of heat. This can be shown as:

Calcium Carbonate = Calcium Oxide + Carbon Dioxide.

CaCO3 = CaO + CO2

Quicklime can become slaked lime (solid state) or limewater (aqueous state) or calcium hydroxide from adding water. This produces heat in an exothermic reaction.

Calcium hydroxide = Calcium Oxide + Water

CaOH2 = CaO + H2

Answer 2

Acids can have different chemical formulas depending on their specific composition. For example, hydrochloric acid has a chemical formula of HCl, sulfuric acid has a formula of H2SO4, and acetic acid has a formula of CH3COOH.
