4FeS2 + 11O2 ----> 2Fe2O3 + 8SO2
The rusting of iron is given by the balanced equation:4Fe + 3O2 --> 2Fe2O3
2
2NaNO3 ==> 2NaNO2 + O2
The coefficient for oxygen is 1, and so is not written. The equation is already balanced.
2c2h6 + 7o2 ---> 4co2 + 6h2o
2h2 + 2o -------> 2h2o
First of all it's a chemical reaction and the formula is Fe2O3 Learn & Enjoy
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.
4K + O2 = 2K2O so the "coefficient" is 1
2Cu+O2 ---> 2CUO
p4+502=p4010

A balanced equation has equal numbers of each type of atom on each side of the equation..The chemical equation describes the balanced reaction between lead and oxygen to form lead oxide is as follows .4Pb + 3O2 → 2Pb2O3.
The reaction between strontium and nitrogen gas (which has the formula N2) produces strontium nitride, which has the formula Sr3N2. The balanced equation is: 3Sr + N2 -> Sr3N2. If there is an excess of oxygen available, the balanced equation for reaction between indium and oxygen is: 4 In + 3 O2 -> 2 In2O3.
