Answer is: C. exothermic reactions.
For example, the Haber process is procedure for the production of ammonia, in this process atmospheric nitrogen (N₂) is converted to ammonia (NH₃) and energy is released:
N₂ + 3H₂ ⇄ 2NH₃ ΔrH = -92 kJ/mol.
There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).

Answer:
(b) amino group
e) carboxyl group
Explanation:
The functional group in an organic compound distinguishes it from other compounds. It is usually the site where chemical reactions takes place.
CH₃-HC(NH₂)-COOH
There are two functional groups in this organic compoud:
- The NH₂ group is called the amino group
- The COOH is a carboxyl group
What elem eat is this? That has three orbitals? Usually the first orbital will contain only two electrons. The second orbital would contain four, the third would contain 16
