Question

NaCl + H2O → NaOH + Cl2 + H2 Balance the equation. Choose "blank" if no coefficient is needed. NaCl + H2O → NaOH + Cl2 ++ H2

Answer 1

The balanced equation is:

2NaCl + 2 H2o → 2 NaOH + Cl2 + H2

1- we put 2 NaCl to balance Cl2 on the other side.
2- we put 2 NaOH to balance Na
3- We put 2 H2O to balance H & O on the to sides

Answer 2

Answer:

$2NaCl+2H_{2}O-->2NaOH+Cl_{2}+H_{2}$

Explanation:

This reaction between sodium chloride and water and it must be an electrochemical reaction where aqueous NaCl undergoes electrolysis given sodium hydroxide chlorine and hydrogen gas.

so the following coefficients are needed

a) Before NaCl : "2"

b) Before H₂O: "2"

c) Before NaOH : "2"

d) Before Cl₂ : none (blank)

e) Before H₂: none (blank)
