Question

Завершите следующие реакции.CaO + H2SO4 → Ca(OH)2+ HCl → ​

Answer 1

Ответ:

1) CaO+ H2SO4 = CaSO4 + H2O

2) Ca(OH)2 + 2 HCl = CaCl2 + 2 H2O

Answer 2

Reaction 1: CaO + H2SO4 → Ca(OH)2

The reaction between calcium oxide (CaO) and sulfuric acid (H2SO4) produces calcium hydroxide (Ca(OH)2).

Calcium oxide (CaO) is a white, crystalline solid commonly known as quicklime. Sulfuric acid (H2SO4) is a strong acid that is commonly used in various industrial processes.

When calcium oxide reacts with sulfuric acid, a neutralization reaction occurs. The sulfuric acid donates two hydrogen ions (H+) to the calcium oxide, resulting in the formation of calcium hydroxide and water.

The balanced chemical equation for this reaction is:

CaO + H2SO4 → Ca(OH)2 + H2O

In this reaction, one molecule of calcium oxide reacts with one molecule of sulfuric acid to produce one molecule of calcium hydroxide and one molecule of water.

Reaction 2: HCl

The reaction involving hydrochloric acid (HCl) is not specified in the question. It is important to provide more information or context to determine the specific reaction involving hydrochloric acid.

Hydrochloric acid is a strong acid commonly used in various industrial and laboratory applications. It is a corrosive, colorless liquid with a pungent odor.

If you have any additional information or context regarding the reaction involving hydrochloric acid, please provide it so that I can assist you further.
