Question

sodium and sulfur react to form sodium sulfide, na2s. na + s → na2s what is the correct balanced chemical reaction? 2na + s → na,s 4na + 2s → 2na,s 4na + s → 2na,s na, + s → na,s

Explanation:

Step1: Count atoms on both sides

For the unbalanced equation \(Na + S
ightarrow Na_2S\), on the left - hand side (LHS), we have 1 \(Na\) atom and 1 \(S\) atom. On the right - hand side (RHS), we have 2 \(Na\) atoms and 1 \(S\) atom.

Step2: Balance \(Na\) atoms

To balance the \(Na\) atoms, we put a coefficient of 2 in front of \(Na\) on the LHS. The equation becomes \(2Na+S
ightarrow Na_2S\). Now, on the LHS, we have 2 \(Na\) atoms and 1 \(S\) atom, and on the RHS, we have 2 \(Na\) atoms and 1 \(S\) atom.

Answer:

\(2Na + S
ightarrow Na_2S\)
