Question

if a chemical reaction does happen, write a balanced chemical equation for it. 3hcl(s)→2h₂(g)+2cl₂(g)

Explanation:

Step1: Check atom conservation

The given equation $3HCl(s)
ightarrow 2H_2(g)+2Cl_2(g)$ is un - balanced. We need to balance the number of hydrogen and chlorine atoms on both sides.

Step2: Adjust coefficients

For hydrogen atoms, on the left - hand side we have 3 H atoms in $3HCl$ and on the right - hand side we have 4 H atoms in $2H_2$. For chlorine atoms, on the left - hand side we have 3 Cl atoms in $3HCl$ and on the right - hand side we have 4 Cl atoms in $2Cl_2$.
The balanced chemical equation should be $4HCl(g)
ightarrow 2H_2(g)+2Cl_2(g)$. Here, on the left - hand side we have 4 H atoms and 4 Cl atoms, and on the right - hand side we also have 4 H atoms and 4 Cl atoms.

Answer:

$4HCl(g)
ightarrow 2H_2(g)+2Cl_2(g)$
