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.
