The balanced equation for the reaction between zinc (Zn) and oxygen (O2) is: 2Zn + O2 -> 2ZnO
keq= [SO2]2[O2]/[SO3]2
1:2, does this need explaining???? 1-O2 for every 2-SO3 thus 1:2
The balanced chemical equation for the reaction between Zn and O2 is 2 Zn + O2 → 2 ZnO. This equation shows that 2 moles of Zn react with 1 mole of O2 to produce 2 moles of ZnO.
O2 is the chemical symbol for oxygen. if something has O2 in it it has 2 oxygen molecules=)
The balanced equation for this decomposition reaction is 2 H2O2 -> 2 H2O + O2.
2Mg + O2 --------> 2MgO
The reactions are:N2 + O2 = 2 NO2 NO + O2 = 2 NO2
This reaction is:2 CO2 = 2 CO + O2
Balanced Equation: 2Mg(NO3)2 = 2MgO + 4NO2 + O2
2H2O2 in the prescence of catalase results in 2 H2O + O2
O2+4e- 2O 2-
