Question

What is the number “4” in SiCl4? a subscript a coefficient a product a reactant

Answer 1

It is a) a subscript

Answer 2

Answer: 4 is the subscript in $SiCl_{4}$.

Explanation:

We know that,

Subscript: The number of atom present in a given compound.

In $SiCl_{4}$, 4 represents the number of chlorine atom in 1 mole of Silicon tetra chloride.

Coefficient: Number of atom which is used in reaction.

For example: In $3SiCl_{4}$, 3 is the coefficient of silicon tetra chloride.

A Product : In the balance equation, right hand side is called product.

A reactant : In the balance equation, left hand side is called reactant.

For example: the balance equation is

$2Mg+O_{2}\rightarrow 2MgO$

In this equation, $2Mg+O_{2}$ is the reactants and $2MgO$ is products.

Hence, 4 is the subscript in $SiCl_{4}$.
