2 answers:
Answer : and
pair of substances are the products.
Explanation :
The given balanced chemical reaction is,
Balanced chemical reaction is the reaction in which the number of atoms of an individual elements present on reactant side must be equal to the product side.
The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.
In the given balanced reaction,
and
are reactants.
and
are products.
Hence, and
pair of substances are the products.

Matter is discontinuous, and it is made of tiny particles called atoms
Explanation:
Matter is not a continuous structure, but it consists of tiny particles called atoms.
An atom consists of three types of particles:
- Proton: the proton is in the nucleus of the atom. it has a positive electric charge of
(also called fundamental charge). Its mass is
.
- Neutron: the neutron is also in the nucleus of the atom, but it has no electric charge. Its mass is similar to the mass of the proton (slightly heavier). Neutrons and protons are held together in the nucleus through the strong nuclear force.
- Electron: electrons are found in a "cloud" outside the nucleus. Electron has negative electric charge equal to
. Its mass is much approximately 1800 times smaller than that of the proton, so it is considered as negligible.
