Question

1. Based on the following balanced equation:

2 H2 + O2 + 2H2O
a. How many moles of O2 are required to react completely with 2.00 moles of H2?
1.00 1.50 2.00 2.50 3.00 3.50 4.00 4.50 5.00
b. How many moles of H2O are produced after complete reaction of 2.00 moles of H2?
1.00 1.50
2.00 2.50 3.00 3.50 4.00 4.50 5.00

Answer 1

a. 1 mole O2

b. 2 moles H2O

Step-by-step explanation:

a. 2 moles H2 x
`(1 mole O2)/(2 moles H2)` = 1 mole O2

B. 2 moles H2 x
`(2 moles H2O)/(2 moles H2)` = 2 moles H20
