Answer:
CH3+
Explanation:
Sp2 hybridization involves the mixing of on s and two p orbitals. This is observed in CH3+. The ion is trigonal planar with a H-C-H bond angle of 120°.
The anion, CH3^- is sp3 hybridized, hence only CH3+ is sp2 hybridized among the options.

C. Energy is released by the reaction
Explanation:-
An exothermic reaction is one in which during the progress of the reaction heat is evolved.
So energy is released by the reaction.
It cannot be created as energy is neither created nor destroyed as per the Law of conservation of energy. Energy is not transferred either.
The energy released during the progress of the reaction originates from the chemical bonds of the reactants as they break during their conversion into products.
Answer:
0.1011 moles of N₂
Explanation:
This is the reaction:
3 Mg + N₂ → Mg₃N₂
3 moles of magnesium can react to 1 mol of nitrogen in order to produce 1 mol of magnesium nitride.
We can solve this by a rule of three:
3 mol of Mg need 1 mol of N₂ for the reaction
Then, 0.3034 moles of Mg may react to (0.3034 . 1) / 3 = 0.1011 moles of nitrogen.
The stoichiometry is 3:1
