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
2C2H2 + 5O2 ---->4CO2 + 2H2O so 1 mole of acetylene (ethyne) reacts with 2.5 moles of oxygen. Answer 2.5 moles
The balanced equation for the reaction is: 3H2 + N2 -> 2NH3 From the balanced equation, we can see that 3 moles of hydrogen are needed to react completely with 1 mole of nitrogen. So if there are 3 moles of nitrogen, you would need 9 moles of hydrogen to react completely.
The balanced chemical equation for the combustion of acetylene is: 2 C2H2 + 5 O2 → 4 CO2 + 2 H2O From the equation, 2 moles of acetylene react with 5 moles of oxygen. Therefore, 12 moles of oxygen would react with 12/5 * 2 = 4.8 moles of acetylene.
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
Two atoms of iron are needed to completely react with three molecules of oxygen to form two molecules of iron(III) oxide (Fe2O3). Each iron atom will lose three electrons to form Fe3+ ions, while each oxygen molecule will gain two electrons to form O2- ions.
How many moles of CO2 are produced when 2.1 mol of C2H2 react?
2C2H2 + 5O2 ---->4CO2 + 2H2O so 1 mole of acetylene (ethyne) reacts with 2.5 moles of oxygen. Answer 2.5 moles
