1. 4 electron domains, no lone pairs
Linear
V
2. 2 electron domains, no lone pairs
Trigonal Pyramidal
3. 3 electron domains, no lone pairs
4. 3 electron domains, 1 lone pair
Trigonal Planar
5. 4 electron domains, 1 lone pair
Tetrahedral

explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

you need to have a picture of the atom that way we can answer it
