If you want to balance the equation, then: 2Zn + O2 --> 2(ZnO)
___Zn + ___O2 --> ___ZnO
The reactants are the substances that are doing the reacting to produce the result. (The substances on the left side of the equation are the reactants) So ZnS & O2 are the reactants.

Calcium (Ca) is element. O2 and CaO are molecules.
Calcium, Ca, and oxygen, O2, are elements (first is mono-atomic, the second is diatomic). Calcium oxide, CaO, is a molecule made of two elements.
5 moles RbNO3 (3 moles O2/2 moles RbNO3) = 7.5 moles oxygen gas produced
2ZnS + 3O2 = 2ZnO + 2SO2
This chemical equation is:2 ZnS + 3 O2 = 2 ZnO + SO2
yeah
2Zn + O2 --> 2ZnO
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
It tells me that you can add in science and that you have to figure out the question.
2 Zn + O2 = 2 ZnO (zinc oxide, a white powder)
2NaH2 + O2 yields 2Na + 2H2O
4Li + O2 -> 2Li2O
n+o2=no2
Endothermic
2SO2 + O2 + 2H2O -------> 2H2SO4
