What is a balanced chemical equation?</h3>
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.
Balanced chemical equation:
→ 
In your case, 2 moles of chlorine gas are needed to produce 1 mole of tetrachloroethane, which implies that there's a 2:1 mole ratio between the two.

Answer:
Molarity of HCl solution = 0.25 M
Explanation:
Given data:
Volume of NaOH= V₁ = 25.0 mL (25/1000 = 0.025 L)
Molarity of NaOH solution=M₁ = 0.185 M
Volume of HCl solution = V₂ = 0.0200 L
Molarity of HCl solution = M₂= ?
Solution:
M₁V₁ = M₂V₂
0.185 M ×0.025 L = M₂ × 0.0200 L
M₂ = 0.185 M ×0.025 L / 0.0200 L
M₂ = 0.005M.L /0.0200 L
M₂ = 0.25 M
The chemical reaction in which number of atoms of each element present in the reactant side is equal to the number of atoms of that element in product side, such reactions are said to be a balanced chemical reaction.
The chemical symbol for sodium is 
.
The chemical symbol for fluorine gas is 
.
The chemical symbol for sodium fluoride is 
The sodium fluoride is prepared from the reaction between sodium metal and fluorine gas can be written as:
The above reaction is not balanced as the number of fluorine atoms are not same on reactant and product side. So, in order to balance the reaction we will multiply with 2 on reactant side and with 2 on product side. Thus, the balanced reaction will be:
Thus, the balanced chemical equation is .
