Question

How many moles of H2O can be formed when 3.5 moles of NH3 react with 2.2 moles of O2?

NH3 + O2 yields NO + H2O

Be sure to balance the equation.

1.8 moles
2.3 moles
2.6 moles
5.2 moles

Answer 1

balence equation is 4NH3+ 5O2 -------> 4NO + 6H2O

Answer 6

4NH3+ 5O2 --> 4NO + 6H2O
3.5 mole of ammonia reacts 2.2 moles
Find the number of moles of NH3 based on 2.2 moles and find the number of moles of O2 based on 3.5 moles to find out the limiting reagent
Look at the mole ratio of NH3 to O2 4:5
2.2*4/5=1.76 moles of ammonia
3.5*5/4=4.375 moles of oxygen
Oxygen is the limiting reagent because the calculate no of moles is greater than the required amound which is 2.2 if it was less than 2.2 oxygen would be in excess
2.2*6/5

Answer 7

The limiting reagent is the reactant that is completely used up during the chemical reaction.
The last step was based on the mole ratio of O2 to H2O which is 5:6

Answer 8

thank youuuuu

Answer 9

so would you say the answer is 2.6 @Abmon98
