Question

1. choose all that apply.

which two products complete the unbalanced decomposition reactions?
\ce{nh_{3} ->delta} ____+____
\square nh
\square \ce{h_{2}}
\square \ce{n_{2}}
\square \ce{h_{2}o}

Explanation:

Step1: Recall Decomposition of Ammonia

Ammonia ($\ce{NH_3}$) decomposes upon heating ($\Delta$) into nitrogen and hydrogen. The reaction involves breaking $\ce{NH_3}$ into its elemental components.

Step2: Identify Products

The elements in $\ce{NH_3}$ are nitrogen (N) and hydrogen (H). Their elemental forms are $\ce{N_2}$ (diatomic nitrogen) and $\ce{H_2}$ (diatomic hydrogen). $\ce{NH}$ is not a stable product here, and $\ce{H_2O}$ has oxygen which isn't in $\ce{NH_3}$, so the products should be $\ce{H_2}$ and $\ce{N_2}$.

Answer:

$\ce{H_2}$ (the option with $\ce{H_2}$), $\ce{N_2}$ (the option with $\ce{N_2}$)
