Question
"Solid zinc oxide is produced by combining zinc powder with oxygen gas." What is the correct skeleton equation for this reaction?
- ZnO(s) → Zn(s) + O2(g)
- ZnO(s) →Zn(s) + O(g)
- Zn(s) + O2(g) → ZnO(s)
- Zn + O → ZnO
Hint:
Skeletal equations are equations with simply the chemical formulas of the products and reactants, no mention of state, and no atom balancing on either side of the equation.
The correct answer is: ZnO(s) → Zn(s) + O2(g)
"Solid zinc oxide is produced by combining zinc powder with oxygen gas." ZnO(s) → Zn(s) + O2(g) is the correct skeleton equation for this reaction.
