When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water
according to the reaction below.
2H2+ O2 + 2H2O
How many grams of oxygen were required?

2H, + O2 + 2H2O
How many grams of oxygen were required?

Mass of Oxygen required : 24 grams

Given

3 moles of H

1.5 moles of O

3 moles of H₂O

Required

Mass of O

Solution

Reaction

2H₂ + O₂ ⇒ 2H₂O

Mass of Oxygen for 1.5 moles of O :

= mol x Ar O

= 1.5 moles x 16 g/mol

= 24 grams

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
