Question

which type of reaction are these
N2+3H2=2NH3
2Pb(NO3)2=2PbO+4NO2+O2
Zn+ 2AgNO3=Zn(NO3)2+2Ag

Answer 1

Answer:

hiiii mate

1. combination reaction.
2. decomposition reaction.
3. double displacement reaction.

Explanation:

hope it helps you ✌️✌️

Answer 2

friend first reaction is very simple

since the first reaction absorbs heat it is endothermic.

but also two reactants combine to form only 1 product so it is also combination.

whereas the second reaction is decomposition reaction as the number of products is more than one while the no . of reactants is one . here also heat is required, so it is endothermic.

third reaction is a displacement reaction since a salt of lower reactive metal is replaced by a higher reactive metal.

plz mark as brainliest if it helps,
