Answer

Explanation:

Step1: Balance sodium (Na) atoms

Let the coefficient of $Na_2HPO_4$ be $x$, the coefficient of $Na_4P_2O_7$ be $y$ and the coefficient of $H_2O$ be $z$. For sodium atoms, we have $2x = 4y$.

Step2: Balance phosphorus (P) atoms

For phosphorus atoms, $x=2y$.

Step3: Balance oxygen (O) and hydrogen (H) atoms

For hydrogen atoms, $x = 2z$; for oxygen atoms, $4x=7y + z$. Substituting $x = 2y$ into $4x=7y + z$, we get $8y=7y + z$, so $y = z$. And since $x = 2y$, if we set $y = 1$, then $x=2$ and $z = 1$.

Answer:

2 $Na_2HPO_4\rightarrow$ 1 $Na_4P_2O_7+$ 1 $H_2O$
