Question

A student used 1.6 moles of NaCl. How many miles of Chlorine gas gas were produced? Use this equation: 2NaCl + 2H2O = 2NaOH + Cl2 + H2

Answer 1

The answer to your question is 0.8 moles of Cl₂

Step-by-step explanation:

Data

moles of NaCl = 1.6

moles of Cl₂ = ?

Process

1.- Check if the reaction is balanced

2NaCl + 2H₂O ⇒ 2NaOH + Cl₂ + H₂

This reaction is balanced.

2.- Use proportions and cross multiplication to solve this problem. Consider the coefficients of the balanced reaction.

2 moles of NaCl ------------------- 1 moles of Cl₂

1.6 moles of NaCl ------------------ x

x = (1.6 x 1) / 2

x = 1.6 / 2

x = 0.8 moles of Cl₂
