# Explanation:
## Step1: Balance oxygen atoms
We have $3$ oxygen atoms in $As_2O_3$. In $H_2O$, for each $H_2O$ molecule, there is $1$ oxygen atom. Let the coefficient of $As_2O_3$ be $a = 1$, and the coefficient of $H_2O$ be $b$. From the oxygen balance: $3=a\times3$ (for $As_2O_3$) and $b$ (for $H_2O$). So $b = 3$.

## Step2: Balance hydrogen atoms
We have $b = 3$ $H_2O$ molecules. Each $H_2O$ has $2$ hydrogen atoms. So the total number of hydrogen atoms on the right - hand side is $2\times3=6$. Let the coefficient of $H_2$ be $c$. Since each $H_2$ molecule has $2$ hydrogen atoms, from $2c=6$, we get $c = 3$.

## Step3: Balance arsenic atoms
We have $a = 1$ $As_2O_3$ molecule. Each $As_2O_3$ has $2$ arsenic atoms. Let the coefficient of $As$ be $d$. From arsenic balance $2=a\times2$ (for $As_2O_3$) and $d$ (for $As$). So $d = 2$.

# Answer:
$1$ $As_2O_3+3$ $H_2
ightarrow2$ $As + 3$ $H_2O$
