Question

Classify the following on the basis of type of the chemical reaction:

i. Mg + Cu(NO3)2 =Mg(NO3)2 + Cu

ii. 2 HgO= 2 Hg + O2

iii. 2 Na + Cl2 =2 NaCl

iv. 2 KI + Pb(NO3)2 =2 KNO3 + PbI2​

Answer 1

Answer:

i. Mg + Cu(NO3)2 =Mg(NO3)2 + cu íѕ díѕplαcєmєnt rєαctíσn

ii. 2 HgO= 2 Hg + O2 íѕ dєcσmpσѕítíσn rєαctíσn

iii. 2 Na + Cl2 =2 nαcl íѕ cσmвínαtíσn rєαctíσn

ív.2 KI + Pb(NO3)2 =2 KNO3 + PbI2 íѕ ѕuвѕtítutíσn rєαctíσn
