This is FALSE. Mass is the measure of matter than an object contains.
Explanation:

Answer :-
None of the forward reaction or backward reaction will be faster at equilibrium as
definition of equilibrium is that phase in which the rate of formation of product from reactant and rate formation of reactant from product is equal
and hence , both will be form at equal rate !!
Answer: Fusion is a type of nuclear reaction.
Explanation:
Nuclear reaction is defined as those reaction in which nucleus of an atom is involved. There are two types of nuclear reaction:
- Fusion : In this type, two or more smaller atomic nuclei are combined together to form larger nucleus with release in energy
- Fission : In this type, one large unstable nucleus breaks down into two smaller nuclei with release in energy.
The atomic size trend in the periodic table is increasing from right to left and from top to bottom. Hence when comparing a chlorine atom and a sodium atom, it is seen that chlorine is seen on the far left side of the periodic table while sodium is seen on the far right side. This means sodium is thus greater in atomic size than a chlorine atom.
