$N a + H_{2} nN a nH + H_{2}$

Step 1

Reorder factors in $N a + H_{2} nN a nH + H_{2}$ .

$N a + H_{2} a nN nH + H_{2}$

Step 2

Reorder $N$ and $a$ .

$a N + H_{2} a nN nH + H_{2}$

Step 3

Reorder $H_{2}$ and $a$ .

$a N + a H_{2} nN nH + H_{2}$

Step 4

Reorder $a N$ and $a H_{2} nN nH$ .

$a H_{2} nN nH + a N + H_{2}$
