generally melting point of mixture is always different from melting point of pure compound
lets say you have a two compounds called A and B
and you have a unknown compound called X which can be either A or B
now your target is to find unknown is really A or B right?
take some amount of X and mix it with A and B separately
out of these two mixtures one will be pure compound (because we initially assume that unknown can be either A or B)
suppose X + A is same melting with A then X is A
X +B will be less than the melting point of A or
suppose X+B is same melting point like B then X is B
X+A will be less than melting point of B
Answer:
False, since boiling is a physical change of state. Although it is at 100°C, it is not a chemical property.

Answer:
I think it’s D
Explanation:
Chemical strength, Chemical compounds have energy contained in their bonds. Chemical energy may be emitted in the form of heat during a chemical reaction, which is known as an exothermic reaction. The body transforms the chemical energy in food into mechanical energy and heat.
