Question

balancing equations - phet simulator
period
instructions: open the balancing chemical equations simulator via the phet website or app.
choose the \introduction\ option. choose the bar graph on the top - right corner in \tools.\
at the bottom of the page, choose the make ammonia option.

1. in the equation, is n₂ considered a reactant or a product?
2. in the equation, is nh₃ considered a reactant or a product?
3. balance the equation using the simulator. write the balanced coefficients below.

1. in the spaces below, draw the particles representing the balanced equation:

Explanation:

Step1: Count atoms

For unbalanced equation \(N_2 + H_2
ightarrow NH_3\), count \(N\) and \(H\) atoms. Left: \(N = 2\), \(H=2\). Right: \(N = 1\), \(H = 3\).

Step2: Balance \(N\) atoms

Put coefficient \(2\) in front of \(NH_3\). Equation becomes \(N_2 + H_2
ightarrow 2NH_3\). Now right - side \(N = 2\), \(H=6\).

Step3: Balance \(H\) atoms

Put coefficient \(3\) in front of \(H_2\). Equation \(N_2+3H_2
ightarrow 2NH_3\). Now left: \(N = 2\), \(H = 6\); right: \(N = 2\), \(H = 6\).

Answer:

\(\boldsymbol{1}\) \(N_2+\boldsymbol{3}\) \(H_2
ightarrow\boldsymbol{2}\) \(NH_3\)
