Question

N2 + 3H2 2NH3 How many molecules of H2 are represented in the reaction? How many nitrogen atoms are represented in the reactants? How many moles of NH3 are formed?

Answer 1

In the given reaction, there are 1.8066 × 10²⁴ molecules of H₂, 6.022 × 10²³ nitrogen atoms, and 3.011 × 10²³ moles of NH₃ formed.

Step-by-step explanation:

The balanced equation for the reaction is:

N₂ + 3H₂ → 2NH₃

From the equation, we can determine the following:

• The number of molecules of H₂ represented in the reaction is 3 times the number of molecules of N₂. So, if we have 6.022 × 10²³ molecules of N₂, we would need 3 times that amount of H₂, which is 1.8066 × 10²⁴ molecules of H₂.
• The number of nitrogen atoms represented in the reactants is the same as the number of nitrogen molecules, which is 6.022 × 10²³ molecules of N₂.
• The number of moles of NH₃ formed is half the number of moles of N₂, since the reaction produces 2 moles of NH₃ for every 1 mole of N₂. Therefore, if we have 6.022 × 10²³ molecules of N₂, we would produce 3.011 × 10²³ moles of NH₃.

Answer 2

There are 3 molecules of H2.
There are 2 atoms of nitrogen presented in the reactants.
2 moles of NH3 are formed.
