Question

counting atoms in chemical equations
nitrogen gas reacts with hydrogen to produce ammonia. use the chemical equation to complete the statements.
n₂ + 3h₂ → 2nh₃
there are nitrogen atoms on the product side.
there are hydrogen atoms on the reactant side.

Explanation:

Step1: Count nitrogen atoms

In \(N_2\), there are \(2\) nitrogen atoms. In \(2NH_3\), each \(NH_3\) has \(1\) nitrogen atom, so \(2\times1 = 2\) nitrogen atoms. Total nitrogen atoms on both sides: \(2\) (from \(N_2\)) and \(2\) (from \(2NH_3\)).

Step2: Count hydrogen atoms

In \(3H_2\), there are \(3\times2=6\) hydrogen atoms. In \(2NH_3\), each \(NH_3\) has \(3\) hydrogen atoms, so \(2\times3 = 6\) hydrogen atoms.

Answer:

Nitrogen atoms: \(2\); Hydrogen atoms: \(6\)
