Answer:
Option-C (Both)
Explanation:
Chemical equation is the representation of a chemical reaction in the form of elemental symbols and molecular formulae.
Parts of Chemical equation are as follow:
a) Left Part:
The left part of the chemical equation shows the Reactants. Reactants are the starting material of a chemical equation which reacts together to form a final product(s).
In given equation Si₂H₃ and O₂ are the reactants.
b) Right Part:
The right part of the chemical equation shows the Products. Products are the substances formed due to the reaction of reactants.
In given equation SiO₂ and H₂O are the products.
c) Coefficient:
It is the number placed infront of a molecule or atom in a chemical equation. It specifies the number of molecules or atoms.
In given equation the number 4 infront of Si₂H₃ implies that there are 4 molecules of Si₂H₃.
d) Subscript:
It is the number placed after an atom in a molecule. It specifies the number of that particular atom in molecule.
In given equation the the number 2 after Si and number 3 after H implies that there are 2 atoms of Si and 3 atoms of H in one molecule of Si₂H₃ respectively.
