When solving the chemical equations of this chain, they will look like this:
1) 2Ca + O2 → 2CaO
Calcium react with oxygen to produce calcium oxide. This reaction takes place at a temperature of over 300 ° C.
2) CaO + H2O → Ca (OH) 2
Calcium oxide react with water to produce calcium hydroxide. The process is called lime slaking.
3) Ca (OH) 2 + H2SO4 → CaSO4 + 2H2O
Calcium hydroxide react with sulfuric acid to produce calcium sulfate and water. Sulfuric acid is a dilute solution.
4) CaSO4 + BaCl2 → CaCl2 + BaSO4
