2 Zn3N2 + 3 O2 ----> 6 ZnO + 2 N2?

Question

Please help me. Select every statement that is true about the equation below. 



-The N on the left has a 2 next to it because it is diatomic molecule.

-The charge on the oxygen on the left is-2.

-the reactants are on the right

-the 3 on the oxygen on the left is called coefficient 

-the reaction is a single replacement reaction

-the charge on Zn on the right is +1

-there are six total oxygen on the left side of the equation

Answer 1

2Zn₃N₂ + 3O₂ ==> 6ZnO + 2N₂

-The N on the left has a 2 next to it because it is diatomic molecule. -False. It has a 2 to balance the charge with the 3 Zn atoms

-The charge on the oxygen on the left is-2. - False. It is zero

-the reactants are on the right - False. Reactants are on the left, products are on the right

-the 3 on the oxygen on the left is called coefficient  - True

-the reaction is a single replacement reaction - True

-the charge on Zn on the right is +1 - False. The charge would be 2+

-there are six total oxygen on the left side of the equation - True
