Question

is the reaction below balanced or unbalanced? *
n₂ + h₂ → nh₃
balanced
unbalanced
the scientific method is *
a checklist of steps for experimentation
a summary or equation that has been repeated endlessly with experimentation
a long explanation of how things work that has been tested again and again

Explanation:

Step1: Count nitrogen atoms

On the left - hand side, in $N_2$, there are 2 nitrogen atoms. On the right - hand side, in $NH_3$, there is 1 nitrogen atom.

Step2: Count hydrogen atoms

On the left - hand side, in $H_2$, there are 2 hydrogen atoms. On the right - hand side, in $NH_3$, there are 3 hydrogen atoms.

Step3: Determine balance

Since the number of nitrogen and hydrogen atoms is not the same on both sides of the equation, the reaction is unbalanced.

Answer:

Unbalanced
