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
The nut has a diameter of 2-4 cm.
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).
SrSO4 + 2H2O + 2NH3
Coefficient-Determines the number of molecules
2 X 3 = 6.
2NH3 + 2NA = 3H2 + NA3N2
Molecular equation: H2SO4 + 2NH3 ---> (NH4)2SO4 Complete ionic equation: 2H++ SO42- + 2NH3 ---> 2NH4+ + SO42- Net ionic: 2H+ + 2NH3 ---> 2NH4+
N2 + 3H2 -------> 2NH3
8 2xN=2 Nitrogen atoms + 2xH3=6 Hydrogen atoms =8 total atoms
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.
(NH4)2(SO4) aq + Ba(OH)2 aq ---> Ba(SO4) solid + 2H2O liquid + 2NH3 gas2H2O liquid + 2NH3 gas came from 2NH4OH
N2 + 3H2 --> 2NH3 N2 + 3H2 --> 2NH3
2NH4Cl + Ba(OH)2 ---> BaCl2 + 2NH3 + 2H2O
