Page 172 Chapter - 8.Metals

Answer 1

Answer:

2mg+O2 -----2mg

Explanation:

mg+2h2o-------mg (oh)2+h2

mg+2hcl ------mgcl2 +h2

Answer 2

Dear Student,

◆ Answers with explaination -

(a) Magnesium metal + dioxygen gas -

Magnesium metal on reaction with dioxygen gas gives magnesium oxide.

2Mg + O2 --> 2MgO

(b) Magnesium metal + water -

Magnesium metal on reaction with steam (not cold water) gives magnesium oxide and hydrogen gas.

Mg + H2O --> MgO + H2

(c) Magnesium metal + dil.HCl -

Magnesium metal on reaction with dil.HCl gives magnesium chloride and hydrogen gas.

Mg + 2HCl --> MgCl2 + H2

(d) Magnesium metal + dichlorine gas -

Magnesium metal on reaction with dichlorine gas gives magnesium chloride.

Mg + Cl2 --> MgCl2

Thanks dear...
