Balance. Ammonia + oxygen yields Nitrogen + water. Then, given the moles of reactant or product below, determine the corresponding amount in moles of each of the other reactants and products.
a)4 mol Ammonia
b)4 mol of Nitrogen
c)4.5 mol oxygen
To determine the corresponding amount in moles of each reactant and product, we need to use the balanced chemical equation. The balanced equation for the reaction is:
4 NH3 + 5 O2 → 4 N2 + 6 H2O
a) 4 mol of ammonia:
According to the balanced equation, the mole ratio between ammonia and nitrogen is 4:4. Since we have 4 moles of ammonia, we can conclude that there will also be 4 moles of nitrogen produced.
b) 4 mol of nitrogen:
Using the above mole ratio, we see that 4 moles of nitrogen correspond to 4 moles of ammonia.
c) 4.5 mol of oxygen:
To determine the corresponding amount in moles of the other reactants/products, we need to find the mole ratio of oxygen in the balanced equation. In this reaction, the mole ratio between oxygen and ammonia is 5:4. Therefore, for every 5 moles of oxygen, we have 4 moles of ammonia.
To calculate the moles of ammonia corresponding to 4.5 moles of oxygen, apply the following steps:
Step 1: Set up a ratio using the mole ratio from the balanced equation:
5 moles of oxygen/4 moles of ammonia
Step 2: Cross multiply and solve for x (the moles of ammonia):
5 moles of oxygen * x = 4.5 moles of oxygen * 4 moles of ammonia
5x = 18
x = 18/5 = 3.6 moles of ammonia
Therefore, given 4.5 moles of oxygen, the corresponding amount in moles of ammonia is approximately 3.6 moles.
4NH3 + 3O2 -> 2N2 + 6H2O
is the balanced reaction
a) 4 moles of NH3 (ammonia) require 3 of O2 to react completely. The balanced formula tells you now many moles of N2 and H2O are formed.
I am sure you can figure out the others
