Answer : The correct chemical reactions are,
Explanation :
Law of conservation of matter : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
The balanced chemical reaction always follow that law of conservation of matter.
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the number of atoms of individual elements present on product side.
(a) The given chemical reaction is,
This reaction is an unbalanced chemical reaction because in this reaction the number of atoms of oxygen and hydrogen are not balanced on both the side. So, it will not obey the law of conservation of matter.
(b) The given chemical reaction is,
This reaction is an unbalanced chemical reaction because in this reaction the number of atoms of oxygen are not balanced on both the side. So, it will not obey the law of conservation of matter.
(c) The given chemical reaction is,
This reaction is a balanced chemical reaction because in this reaction number of atoms of individual elements present on reactant side are equal to the number of atoms of individual elements present on product side. So, it obey the law of conservation of matter.
(d) The given chemical reaction is,
This reaction is a balanced chemical reaction. So, it obey the law of conservation of matter.
(e) The given chemical reaction is,
This reaction is an unbalanced chemical reaction because in this reaction the number of atoms of oxygen are not balanced on both the side. So, it will not obey the law of conservation of matter.
