Answer:

3 a).Yes. Zinc has less reactive compared to Hydrogen.

Hydrogen attracts oxygen more than Zn as Zinc is bigger in size and is more loosely bound to the oxygen atoms.

    Zn O2 + 2 H2 => Zn + 2 H2 O

b)Law of conservation of matter : It states that matter can neither be created nor be destroyed but it can only be transformed from one form to another form.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The given chemical reaction is,

This reaction is a balanced chemical reaction in which number of atoms of hydrogen and oxygen are equal on the both side of the reaction. So, this reaction obey the law of conservation of matter.
