If you want to balance the equation, then: 2Zn + O2 --> 2(ZnO)
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.
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.
5 moles RbNO3 (3 moles O2/2 moles RbNO3) = 7.5 moles oxygen gas produced
The equation is: N2(g) + 2O2(g) -> 2NO2(g) Given enthalpy changes: 2NO(g) + O2(g) + 112 kJ -> 2NO2(g) N2(g) + O2(g) -> 2NO(g) + 180 kJ Using Hess's Law, we subtract the second equation from the sum of the first and third equations: 2NO2(g) - (2NO(g) + O2(g)) = 2NO2(g) - 2NO(g) - O2(g), resulting in the entropy change for the third reaction.
It forms Nitrogen Dioxide. 2NO + O2 -> 2NO2
First, capitalization matters in chemistry. The proper formula for nitrogen monoxide (nitric oxide) is NO. No is the symbol for the element nobelium. The balanced equation is 2NO + O2 --> 2NO2
When heat is applied to the reaction 2NO + O2 → 2NO2, the activation energy required for the reaction to take place is provided. This allows the molecules to overcome the energy barrier and react at a faster rate, leading to the formation of nitrogen dioxide (NO2) from nitrogen oxide (NO) and oxygen (O2).

2NO + O2 --> NO2 is not balanced. There are two nitrogen atoms on the left and only one on the right. There are four oxygen atoms on the left and only one on the right. The correct balanced equation is 2NO + O2 --> 2NO2.

This is a balanced chemical equation representing the reaction between nitrogen dioxide and oxygen gas to form nitrogen dioxide. The stoichiometry of the reaction shows that 2 moles of NO react with 1 mole of O2 to produce 2 moles of NO2.
The chemical formula for that reaction is 2n2o5 -->2 no2+3o2. It describes the process of two distinct compounds coming together to form two new ones.
Balanced equation of nitric oxide is no3 2-
2NaH2 + O2 yields 2Na + 2H2O
