Question

6 fill in the blank 1 point balance the following chemical equation: type your answer... na + type your answer... h₂o ---> type your answer... naoh + type your answer... h₂ make sure to include the 1’s if necessary.

Explanation:

Step1: List unbalanced atom counts

Left: Na=1, H=2, O=1; Right: Na=1, H=3, O=1

Step2: Balance H and O first

Add coefficient 2 to $\text{H}_2\text{O}$ and $\text{NaOH}$:
Left: Na=1, H=4, O=2; Right: Na=2, H=4, O=2

Step3: Balance Na

Add coefficient 2 to $\text{Na}$:
Left: Na=2, H=4, O=2; Right: Na=2, H=4, O=2

Step4: Balance remaining H

Add coefficient 1 to $\text{H}_2$ (simplifies to final balanced equation)

Answer:

2 Na + 2 H₂O ---> 2 NaOH + 1 H₂
