A heterogeneous mixture is a mixture in which its components retain their identity. The correct answer is B.
First off, you must realize that the phase changes are marked by the points B and D on the graph. They are level because all of the energy (or heat) being added is being consumed by the physical process. So The temperature is increasing before the phase change, and after the phase change. The moments before and after are represented by points A, C, and E.
Answer:
B
It defines the concept of conservation of matter.
Explanation:
Answer:

Explanation:
exothermic reactions have a negative ∆H
i.e, product of the reaction is less that the reactants of the reaction
(Note : ∆H= products - reactants), that's why it's exothermic
