1 nh3+ 2o2 >>>>> 1hno3 + 1h2o
NH3 + 2O2 --> HNO3 + H2O
The coefficient of oxygen is 2.
Nh4no3 --> n2o + 2h2o
2
2NaNO3 ==> 2NaNO2 + O2
C(s) + O2(g) -> CO2(g)
No.for a start you have potassium on one side (K) and sodium on the other (Na) and what has happened to the Oxygen (O).Your chemical equation does not make any sense.
4FeS2 + 11O2 ----> 2Fe2O3 + 8SO2
2
2NaNO3 ==> 2NaNO2 + O2
Aluminium + Oxygen = Aluminium Oxide 2 Al + O2 = 2AlO2
C(s) + O2(g) -> CO2(g)
2Li + O --> Li2O
The complete combustion of ethanol in oxygen proceeds according to the balanced equation C2H6O + 3 O2 -> 2 CO2 + 3 H2O.
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
Because on one side you have two hydrogens and two oxygens and on the other side of the equation you have two hydrogens and only one oxygen.
4K + O2 = 2K2O so the "coefficient" is 1
2Cu+O2 ---> 2CUO
p4+502=p4010
