Answer:

1 ) Ans:-  N2(g) + 3H2(g) ⇔ 2NH3(g)

2) (a) Ans:- Precipitation is that type of reaction in which the solid substance came out after the reaction and this solid substance is insoluble in water.

For example:-2KI(s) + Pb(NO3) 2(s) → 2KNO3(aq) + PbI2(s)

b) Ans:- The reaction in which two or more than two compounds react to form a single product is called combination reaction.

For example:- CaO + CO2 →   CaCO3

(c) Ans:- The common name of CaOCI2 is bleaching powder. Bleaching powder is used to disinfect drinking water.

Bleaching powder is prepared by passing chlorine gas over dry slaked lime

Ca(OH)2 + Cl2 →  CaOCl2 + H2O

1) 3 H2(g) +N2(g) -----> 2 NH3(g)

2) The reaction in which one of the products formed is an insoluble substance and is thrown out of the substance as solid is called precipitation reaction.

eg:AlCl3 + 3NH4OH---->Al(OH) 3↓+3 NH4Cl

b)The type of reaction in which two or more substances combine to form a single substance is called combination reaction.

eg: 2Mg+ O2 → 2MgO

c) CaOCl2= Bleaching powder

Bleaching powder is manufactured by the action of chlorine on slakedlime powder at 35 degree Celsius.

Ca(OH) 2+ Cl2→ CaOCl2 +H2O

It is used as disinfectant and germicide.
