0.1 mol of zinc reacts with oxygen. How much oxygen is required? How much zinc oxide is formed?

First, you need to write down the reaction equation.

O2 + 2Zn = 2ZnO.

According to the reaction equation, we first determine the amount of oxygen, using the reaction equation.

X mole of oxygen is 2 mole of zinc.

1 mole of oxygen – 2 mole of zinc.

X = 1 * 2: 2 = 1 mol.

Therefore, 1 mole of oxygen will enter into the reaction.

Next, determine the amount of zinc oxide substance.

2 mol of zinc – for a mol of ZnO.

2 mol zinc, – 2 mol ZnO.

Y = 2 * 2: 2 = 2 moles of zinc oxide.

Answer: the amount of oxygen is equal to 1 mol.
