The equation for the combustion of methane is CH4 + 2 O2 -> CO2 + 2 H2O. This means that for every mole of methane, two moles of oxygen are needed. In .009 g of methane, there are .00561 moles (molar mass of methane: 16.0425 g/mol). So there are .01122 moles of oxygen, meaning that with a molar mass of 31.9988 g/mol, there are .18 grams of O2 needed.
what is the mass in grams of oxygen, is needed to complete combustion of 6 L of methane?
take the balanced equation CH4+2O2---->CO2+2H2O.16g need 32g of O2.So 74.5g need 149g of O2
2C2H6+7O2----->4CO2+6H2O
74g of C2H6= 2.4667 mol of C2H6
from the ratio(2/7), 8.633 mol of O2 are needed which is 276.256g (8.633mol×32g(molar mass))
7,98 moles of oxygen are needed to completely oxidize 64g CH4.
The equation for complete combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2OSo, each 1 mole of CH4 requires 2 moles of O2. Therefore 3.0 moles of CH4 requires 6.0 moles O2.
6 moles
Balanced equation: 2H2S + 302 = 2SO2 + 2H20
4 C3H8 + 20 O2 ---> 12 CO2 + 16 H2O So 20 mol of O2 are needed.
H2S (g) + 2 O2 (g) --> H2SO4 (l) 1 mole + 2 mole --> 1 mole You will need 2 moles of O2
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
Balanced equation: 2H2S + 302 = 2SO2 + 2H20
8,75 moles of oxygen are needed.
4 C3H8 + 20 O2 ---> 12 CO2 + 16 H2O So 20 mol of O2 are needed.
16,875 moles of oxygen are needed.
H2S (g) + 2 O2 (g) --> H2SO4 (l) 1 mole + 2 mole --> 1 mole You will need 2 moles of O2
0. Hydrogen doesn't "reackt" to form Nitrogen Monoxide.
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
4NH3 + 3O2 -----> 2N2 + 6H2O 4 moles of ammonia react with 3 of oxygen. So 10 moles of ammonia requires 7.5 moles of oxygen.
0,5 moles Cl-
1 mole
The balanced equation is C3H8 + 5O2 ---> 3CO2 + 4H2O moles C3H8 = 23.7 g x 1 mol/44 g = 0.539 moles moles O2 needed = 5 x 0.539 moles = 2.695 moles O2 (it takes 5 moles O2 per mole C3H8) grams O2 needed = 2.695 moles x 32 g/mole = 86.2 grams O2 needed (3 sig figs)
.913 moles
