Question

The following balanced equation shows the formation of water.

2H2 + O2 → 2H2O


How many moles of oxygen (O2) are required to react completely with 1.67 mol H2?


0.835 mol O2


1.67 mol O2

3.34 mol O2


6.68 mol O2


i am very confused because none of my answers are even close. if you answer this please try not to use complex terms cause my brain is not functioning properly today lol.

Answer 1

Below

Step-by-step explanation:

From the balanced equation given, the number of moles of O2 is 1/2 the moles of H2 ( they are in a O2 : H2 ratio of 1 :2)

1/2 of 1.67 = .835 mole of O2
