Final answer:

The balanced chemical equation for the reaction between nitrogen gas (N₂) and hydrogen gas (H₂) to form ammonia (NH₃) is N₂(g) + 3H₂(g) → 2NH₃(g).

This correct answer is a)

Step-by-step explanation:

The balanced chemical equation for the reaction between nitrogen (N₂) gas and hydrogen (H₂) gas to form ammonia (NH₃) involves ensuring that the same number of atoms of each element are present on both the reactant and product sides of the equation.

The balanced equation is as follows:

3H2 + N2 →2NH3

Here's a step-by-step explanation of how the equation is balanced:

Write the unbalanced equation:

N2 +3H2 →NH3

Balance the number of nitrogen atoms:

N2 +3H2 →2NH3

Balance the number of hydrogen atoms:

3H2 +N2 →2NH3

Now, the equation is balanced, indicating that three molecules of hydrogen gas react with one molecule of nitrogen gas to produce two molecules of ammonia.

This correct answer is a)
