how many moles of NH3 does it take to make 8.0 mol of H20 according to the reaction shown below?
4NH3 + 5O2 --> 4NO + 6H2O
I REALLY NEED HELP WITH THIS AS I AM LOST. PLEASE PROVIDE NOTES.
the ratio of NH3 to H2O is 4:6 or 2:3
NH3 / 2 = H2O / 3
NH3 = 2/3 * H2O
2/3 * 8 = ?
To determine the number of moles of NH3 required to produce 8.0 mol of H2O, you'll need to use the balanced equation provided. Here's a step-by-step explanation of how to solve the problem:
Step 1: Write down the balanced equation:
4NH3 + 5O2 --> 4NO + 6H2O
The coefficients in the balanced equation represent the mole ratio between the reactants and products.
Step 2: Identify the mole ratio between NH3 and H2O:
From the balanced equation, you can see that for every 6 moles of H2O produced, you need 4 moles of NH3.
Step 3: Set up a ratio calculation:
Using the mole ratio from Step 2, you can set up a ratio calculation to find the number of moles of NH3:
4 moles of NH3 / 6 moles of H2O = x moles of NH3 / 8.0 moles of H2O
Step 4: Solve for x (the number of moles of NH3):
Using the ratio calculation from Step 3, you cross-multiply and solve for x:
(4 moles of NH3 * 8.0 moles of H2O) / 6 moles of H2O = x moles of NH3
Step 5: Calculate the number of moles of NH3:
Simplifying the calculation in Step 4 will give you the answer:
x moles of NH3 = 32.0 moles of NH3 / 6 moles of H2O
Therefore, it takes approximately 5.3 moles of NH3 to produce 8.0 moles of H2O according to the given reaction.
