Based on the chemical equation, to balance the given equation we should use 2 as a coefficients of HCl on reacatnt side of the reaction.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each entities are present in same amount on reactant side as well as on the product side of the chemical reaction.
Given chemical reaction is:
Zn + HCl → ZnCl₂ + H₂
In the above reaction equation is not balanced as number of chlorine and hydrogen atoms are not equal on both sides, so balanced equation will be:
Zn + 2HCl → ZnCl₂ + H₂
Hence we add 2 as a coefficient of HCl to balance the equation.

Protons, it was once organized by atomic mass but organizing by protons turned out to be better
Boiling point of ethanol is 78.5
of ethanol is
The relationship between boiling point elevation of a solution and molality can be represented as,
Δ
Molality of the solution (m) =
= 0.234 m
Therefore the boiling point of solution will be 73.8
