If anyone could help me it would be greatly appreciated. I have been working on this all weekend and can’t figure it out. _Al + ___O2 = _Al2O3
1. How many moles of aluminum oxide would be produced if 5.50 mol aluminum is reacted
with sufficient oxygen?

_H2 + _O2 = _H2O
2. If hydrogen gas is reacted with oxygen gas to produce water, how many moles of oxygen are required to produce 12.0 moles of water?

3. For the reaction in No.1 above, how many grams of aluminum oxide would be produced if 54.0g aluminum is reacted with sufficient oxygen?

_CaC2 + _H2O=_C2H2 + _Ca(OH)2
4. Calcium carbide, CaC2, reacts with water to produce acetylene, C2H2, and calcium hydroxide. How many grams of acetylene are produced from reacting 128.2g CaC2 with sufficient water?

_C2H2 + _O2 = _CO2 + _H2O
5. If the reactants and products were all gases at STP, how many liters of oxygen would be required for the complete combustion of 10.0 L C2H2 in a cutting torch? How many liters of CO2 would be produced?

_O2 + _H2 = _H2O
6. How many liters of water vapor would be produced by reacting 2.5 L oxygen gas with sufficient hydrogen gas, if all gases were at STP? How many liters of hydrogen would be needed?

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
