Question

Sr - SrO - Sr(OH)2 - SrCl2

Answer 1

Ответ:

1) 2Sr + O2 = 2SrO

2) SrO + H2O = Sr(OH)2

3) Sr(OH)2 + 2HCl = SrCl2 + 2H2O

Объяснение:

Answer 2

The sequence you provided represents the chemical formulas of compounds containing strontium (Sr) and different elements or groups. Let's break down each compound:

1. Sr: This represents elemental strontium, which is an alkaline earth metal.

2. SrO: This is strontium oxide. It is formed when strontium reacts with oxygen. The chemical formula indicates that one atom of strontium combines with one atom of oxygen to form SrO.

3. Sr(OH)2: This is strontium hydroxide. It is formed when strontium reacts with water (H2O) or hydroxide ions (OH-). The chemical formula indicates that one atom of strontium combines with two hydroxide ions to form Sr(OH)2.

4. SrCl2: This is strontium chloride. It is formed when strontium reacts with chlorine. The chemical formula indicates that one atom of strontium combines with two atoms of chlorine to form SrCl2.

These compounds demonstrate the different chemical reactions that strontium can undergo with oxygen, hydroxide ions, and chlorine to form various strontium-containing compounds.
