The coefficient (in this case a 2) indicates the number of moles or molecules of the compound. So, 2NH3 means there are 2 moles or 2 molecules of ammonia (NH3).
N2 + 3H2 -------> 2NH3
Mn is for manganese I think. Ok first of all check the number of molecules on each side. on the left, Mn has 1, Oxygen has 2, Nitrogen has 1, Hydrogen has 4. On the right hand, Mn has 2,Oxygen has 3, nitrogen has 1 and Hydrogen has 5. all need to be balanced.So the resulting coefficients on both sides should be;2(MnO2) + 2(NH4) --- > Mn2O3 + 2(NH3) + H2O
K(eq)= 1.33
65 centimeters is 2 feet and 1.59 inches.

The coefficient (in this case a 2) indicates the number of moles or molecules of the compound. So, 2NH3 means there are 2 moles or 2 molecules of ammonia (NH3).
There are 2 nitrogen atoms in 2NH3.
SrSO4 + 2H2O + 2NH3
8 2xN=2 Nitrogen atoms + 2xH3=6 Hydrogen atoms =8 total atoms
Cu + 2NH3 → [Cu(NH3)2]+
2NH3 + 2NA = 3H2 + NA3N2
2NH3 molecules contain a total of 6 hydrogen atoms. This is because each NH3 molecule has 3 hydrogen atoms, and there are 2 NH3 molecules in the given compound.
Coefficient-Determines the number of molecules
Molecular equation: H2SO4 + 2NH3 ---> (NH4)2SO4 Complete ionic equation: 2H++ SO42- + 2NH3 ---> 2NH4+ + SO42- Net ionic: 2H+ + 2NH3 ---> 2NH4+
3H2 + N2 --> 2NH3 Since Hydrogen (H) and Nitrogen (N) both appear in nature diatomically they only appear as H2 and N2. We must add 3 molecules of Hydrogen and 1 molecule of Nitrogen to get 2 molecules of ammonia. We cannot, in nature, have half of a diatomic Hydrogen or Nitrogen atom, for that reason the equation must yield 2 molecules of Ammonia.
The balanced equation for this reaction is: N2(g) + 3H2(g) → 2NH3(g).
N2 + 3H2 -------> 2NH3
