Question

Са - СаО - Са ( ОН ) 2 - Са SО4​

Answer 1

Ответ:

1) 2Са + О2 = 2СаО

2) СаО + Н2О = Са(ОН)2

3) Са(ОН)2 + H2SO4 = CaSO4 + 2H2O

Answer 2

The chemical equation you've provided appears to represent a series of chemical reactions involving calcium (Ca) and various compounds. It seems like you're starting with calcium (Ca) and eventually forming calcium sulfate (CaSO4). Here's a breakdown of the reactions:

1. Ca + O2 → CaO This reaction represents the formation of calcium oxide (CaO) from calcium (Ca) and oxygen (O2).

2. CaO + H2O → Ca(OH)2 Here, calcium oxide (CaO) reacts with water (H2O) to form calcium hydroxide (Ca(OH)2).

3. Ca(OH)2 + H2SO4 → CaSO4 + 2H2O This reaction represents the reaction of calcium hydroxide (Ca(OH)2) with sulfuric acid (H2SO4) to produce calcium sulfate (CaSO4) and water (H2O).

So, the overall reaction from Ca to CaSO4 can be written as:

Ca + O2 + H2O + H2SO4 → CaSO4 + 2H2O

Simplifying it:

Ca + O2 + H2SO4 → CaSO4

This equation shows the transformation of calcium into calcium sulfate through a series of reactions involving oxygen, water, and sulfuric acid.
