The reaction is:
2 C2H2 + 5 O2 = 4 CO2 + 2 H2O
The answer is 4,8 moles oxygen.

So 12 mole O2 react with 12*(2/5) = 4.8 mole C2H2

How many mols of O2 are needed to completely react with 7 mols of C2H2?
I have already balanced - 2C2H2+5O2->4CO2+2H2O what do I do next? 2 moles acetylene--------------5 moles oxygen O2 7 moles acetylene--------------x moles oxygen O2 x = 7 x 5/2 = 17,5
How many moles of oxygen are required to react completely with 1.0 mole of c2h2?
2C2H2 + 5O2 ---->4CO2 + 2H2O so 1 mole of acetylene (ethyne) reacts with 2.5 moles of oxygen. Answer 2.5 moles
How many moles of oxygen are needed to react completely with 2.3 moles of H2S?
Balanced equation: 2H2S + 302 = 2SO2 + 2H20
Estimate the heat of combustion for one mole of acetylene?
The heat of combustion refers to the energy that is released as heat when a compound undergoes complete combustion with oxygen under standard conditions. The heat of combustion of acetylene at 25 degrees Celsius is roughly around 1300 kJ/mol.
How many moles of oxygen are necessary to react completely with 4 moles of propane?
4 C3H8 + 20 O2 ---> 12 CO2 + 16 H2O So 20 mol of O2 are needed.

How many moles of oxygen are required to react completely with 1.0 mole of c2h2?
2C2H2 + 5O2 ---->4CO2 + 2H2O so 1 mole of acetylene (ethyne) reacts with 2.5 moles of oxygen. Answer 2.5 moles
How many moles of Co2 will be produced from the reaction of three moles of acetylene with excess oxygen?
6 moles
Acetylene gas C2H2 reacts with oxygen If 2 moles of acetylene react completely with oxygen how many grams of carbon dioxide are produced?
First you need to work out the balanced equation. 2C2H2 + 5O2 -----> 4CO2 + 2H2O From this we see that 2 moles of acetylene produces 4 moles of carbon dioxide. 1 mole of carbon dioxide is 12 + 16 + 16 = 44g (adding the mass numbers of the component elements). If 1 mole = 44g then 4 mole = 176g

How many moles of oxygen are needed to burn 7.0 mols of phosphorus?
8,75 moles of oxygen are needed.
How many moles of oxygen are necessary to react completely with 4 moles of propane?
4 C3H8 + 20 O2 ---> 12 CO2 + 16 H2O So 20 mol of O2 are needed.
How many moles of O2 are needed to burn 1.35mol of C8H18?
16,875 moles of oxygen are needed.
How many moles of oxygen are needed to react completely with 2.3 moles of H2S 2H2S plus 3O2 2SO2 plus 2H2O?
H2S (g) + 2 O2 (g) --> H2SO4 (l) 1 mole + 2 mole --> 1 mole You will need 2 moles of O2
If 4 moles of hydrogen is completely oxidized with oxygen how many moles of oxygen will be consumed?
0. Hydrogen doesn't "reackt" to form Nitrogen Monoxide.
How many moles of oxygen gas are needed to react with 10.0 mol of ammonia?
4NH3 + 3O2 -----> 2N2 + 6H2O 4 moles of ammonia react with 3 of oxygen. So 10 moles of ammonia requires 7.5 moles of oxygen.
