How can balance NH3 plus O2 - NO plus H2O?
NH3 + O2 → NO + H2O
The easy way is to balance the most unbalanced atoms first.
3 H on left side, 2 H on right, make 6 H on both sides by multiplying 2 * NH3 and 3 * H2O
2 NH3 + O2 → NO +3 H2O
2 N on left, 1 N on right, make 2 N on right, 2 NO
2 NH3 + O2 → 2 NO +3 H2O
2 O on left, 5 O on right, make 10 O on both sides, 4 NO + 6 H2O
2 NH3 + 5 O2 → 4 NO +6 H2O
4 N on right, 2 N on left, make 4 N on left, 4 NO
4 NH3 + 5 O2 → 4 NO +6 H2O
Check
4N = 4N
12 H = 12 H
10 O = (4 + 6) 10 O
Ok
Now let me show a method that always works and is more organized.
Determine the charge of each atom. If necessary, check the electronegativity of an atom to determine if it is negative or positive.
For example in NH3, the N is on the left and the H is on the right, so you might think the N is positive and the H is negative. However the EN of H = 2.20 and the EN of N = 3.04. Since the EN of N is greater than the EN of H, the N has a stronger attraction for the pair of bonding electrons. So the N is considered negative and the H is positive.
H only has 2 electron, so it can only donate 1 electron to the N atom, so the charge on the H atom = +1, making the charge on N = -3.
N = -3
H = +1 ,as usual
N^-3(H^+1)3
When you write the charges, write them as superscripts!
The 3 at the end is a subscript.
Yahoo answers will not recognize and transmit superscripts of subscripts.
O2
O2 = (O^0)2
O2 = 0 charge
Any free (unbonded element) or one bonded to itself has a charge = 0.
NO
EN of O = 3.44
EN of N = 3.44
So O = -2
N = +2
N^+2 O^-2
H2O
O has greater EN, so
O = -2
H = +1
(H+1)2 O-2
Determine which element's atoms have changed charge as they changed from reactant to product.(left side to right side) To change charge, an atom either supplies electrons or attracts (gains) electrons
NH3 + O2 → NO + H2O
N^-3 → N^+2 in NO
To change from -3 to +2, the N atom gains 5 e-.
(O^0)2 → 2 O-2 in NO
For two O atoms to change from 0 to -2, each O atom must supply 2 e-, so O2 supplies 4 e-.
Here are the half-equations that show the electron exchange.
N^-3 → N^+2 + 5e-
(O^0)2 + 4 e- → 2 O-2
Notice N supplies 5 e- each time an N atom changes from -3 to +2.
Notice O gains 2 e- each time an O atom changes from 0 to -2, so O2 gains 4 e- each time an O2 changes from 0 to -2.
Like common denominators, for this exchange to occur one time. 20 e- most be exchanged. So, the N exchange occurs 4 times to supply enough e- for the O exchange to occur 5 times.
See the equations below:
4 N^-3 → 4 N^+2 + 20e-
5 (O^0)2 + 20 e- → 10 O-2
This 4 N's must appear in the original equation.
This 10 O's must appear in the original equation.

N2H4 + 2H2O2 -> N2 + 4H2O 1.5 moles N2H4 (4 mole H2O/1 mole N2H4) = 6.0 moles water produced
The balanced equation for the reaction is: N2H4 + H2O2 -> N2 + H2O The coefficients for the balanced equation are: 1 N2H4 + 1 H2O2 -> 1 N2 + 2 H2O
3N2H4 --> 4NH3 + N2 is the correctly balanced equation.
The equation FeSO4 = Fe2O3 + SO2 + SO3 is not balanced. To balance it, one possible balanced equation could be: 2FeSO4 = Fe2O3 + 2SO2 + 2SO3.
First, balance the atoms in the reaction and determine the oxidation states. Then adjust the number of water molecules to balance oxygen atoms and add OH- ions to balance hydrogen atoms. Finally, balance the charges by adding electrons to one side of the reaction. Check that the charges and atoms are balanced in both the half-reactions and overall reaction.
N2H4 + 2H2O2 -> N2 + 4H2O 1.5 moles N2H4 (4 mole H2O/1 mole N2H4) = 6.0 moles water produced
The balanced equation for the reaction is: N2H4 + H2O2 -> N2 + H2O The coefficients for the balanced equation are: 1 N2H4 + 1 H2O2 -> 1 N2 + 2 H2O
First, calculate the molar mass of N2H4 (hydrazine) to be 32 g/mol. Use the stoichiometry of the balanced equation to find the molar ratio of N2H4 to H2O, which is 1:4. Next, determine the number of moles of N2H4 in 27 grams and then use the molar ratio to find the number of moles of H2O produced. Finally, convert the moles of H2O to grams using the molar mass of H2O (18 g/mol).
The balanced reaction for N2H4 + H2O2 --> N2 + H2O is N2H4 + 2H2O2 --> N2 + 4H2O
N2H4 + O2 >> N2 + 2H2O ( for some reason the capitals will not remain when I click save )
This is an oxidation-reduction reaction.
3N2H4 --> 4NH3 + N2 is the correctly balanced equation.
The Smart Balance Omega Plus is still in grocery stores. However, if its not in yours, maybe you could request they carry it. Some stores do that if you ask.

The balance is 2N2 +2O2= 4NO
"Secular term"? I wasn't aware there was a religious term for it. Nitrogen plus hydrogen is "nitrogen and hydrogen". The two can combine chemically to form ammonia (NH3) or hydrazine (N2H4). Other combinations are possible but unlikely.
