Nitrogen (N2) and hydrogen (H2) react to form ammonia (NH3). Consider a mixture of six nitrogen molecules and six hydrogen molecules in a closed container. Assuming the reaction goes to completion, what will the final product mixture be?
number of NH3 molecules?
number of N2 molecules?
number of H2 molecules?
How do i go about finding these?
I know the reaction is N2+3H2--> 2NH3
You know you wont have enough H2 molecules, you only have six H2, and you need only 2 N2 to react with those to create 4 (you get 2NH2 for each one N2). Can you take it from here?
To find the number of NH3 molecules, N2 molecules, and H2 molecules in the final product mixture, you can use the stoichiometry of the reaction and the given information.
1. Start with the given information: a mixture of 6 N2 molecules and 6 H2 molecules.
2. Use the balanced chemical equation to determine the mole ratio between N2 and NH3: N2 + 3H2 -> 2NH3. According to this equation, for every 1 N2 molecule, 2 NH3 molecules are produced.
3. Calculate the number of moles of N2: Since there are 6 N2 molecules in the mixture, the number of moles of N2 is 6/Avogadro's number (6.022 x 10^23 molecules/mol).
4. Use the mole ratio from the balanced equation to determine the number of moles of NH3: Multiply the number of moles of N2 by the mole ratio. In this case, since the mole ratio of N2 to NH3 is 1:2, you would multiply the number of moles of N2 by 2.
5. Convert the number of moles of NH3 back to the number of NH3 molecules: Multiply the number of moles of NH3 by Avogadro's number.
6. Repeat steps 3-5 for H2 to find the number of H2 molecules in the final product mixture.
So, by following these steps, you can find the number of NH3 molecules, N2 molecules, and H2 molecules in the final product mixture.
