Find the number of moles of water that can be formed if you have 130 mol of hydrogen gas and 60 mol of oxygen gas.

130 moles of water might be produced by the reaction.

Explanation:

We state the equation for production of water:

2H₂(g) + O₂ (g) → 2H₂O (l)

Moles of hydrogen: 130

Moles of oxygen: 60

We state that the limting reactant is the oxygen

For 2 moles of hydrogen, we need 1 mol of oxygen

For 130 moles of hydrogen, we would need 65 moles, and we only have 60. Ratio is 2:1

1 mol of O₂ can produce 2 moles of water

Then, 60 moles of O₂ will produce (60 . 2) /1 = 130 moles

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
