Question 1 What happens when metals react with chlorine?
Question 2 What happens when metals react with hydrogen?
Reaction of metal with chlorine
Metals react with chlorine to form ionic chlorides.
2Na(s) + Cl2 (g) —–> 2 NaCl(s)
Ca (s) + Cl2 (g) —–> CaCl2
Mg (s) + Cl2 (g) —-> MgCl2
Reaction of metals with hydrogen
Most of the metals do not combine with hydrogen.Only a few reactive metals like sodium,potassium,calcium and magnesium react with hydrogen to form metal hydrides.
