Balance the following equations by adding the stoichiometric ratios and inserting their physical state (s, l, g or aq).  Do not leave the boxes blank or it will mark you incorrect.  If the stoichiometry is 1 please insert 1 in the box(es) below.  Nitrogen and hydrogen react to produce ammonia. N2( )   +    H2( )   →    NH3( )

The balanced chemical equation for the reaction between nitrogen and hydrogen to produce ammonia is:

N2(g) + 3H2(g) → 2NH3(g)

Here's the step-by-step process:

1. Write down the unbalanced equation: N2 + H2 → NH3
2. Balance the nitrogen atoms first. There are 2 nitrogen atoms on the left side and only 1 on the right side. To balance this, put a 2 in front of NH3: N2 + H2 → 2NH3
3. Now, balance the hydrogen atoms. There are 2 hydrogen atoms on the left side and 6 on the right side (because 2NH3 means there are 2*3=6 hydrogen atoms). To balance this, put a 3 in front of H2: N2 + 3H2 → 2NH3
4. Check to make sure the equation is balanced. There are 2 nitrogen atoms and 6 hydrogen atoms on both sides of the equation.
5. Finally, insert the physical state of each substance. Nitrogen, hydrogen, and ammonia are all gases in this reaction: N2(g) + 3H2(g) → 2NH3(g)

The balanced equation for the reaction of nitrogen and hydrogen to produce ammonia is:

N2(g) + 3H2(g) → 2NH3(g)

The stoichiometric ratios are as follows:

• For N2(g), it is 1.
• For H2(g), it is 3.
• For NH3(g), it is 2.

The physical states are as follows:

• For N2, it is gas (g).
• For H2, it is gas (g).
• For NH3, it is gas (g).

So, the balanced equation with stoichiometric ratios and physical states is:

1 N2(g) + 3 H2(g) → 2 NH3(g)
