What amount of zinc substance is formed as a result of the interaction of zinc oxide with hydrogen

What amount of zinc substance is formed as a result of the interaction of zinc oxide with hydrogen, the volume of which is 22 liters?

1. Let’s solve the problem based on the equation:
ZnO + H2 = Zn + H2O – ОВР, zinc metal is released:
2. Let’s calculate the number of H2 moles, applying Avogadro’s law:
1 mol of gas at n. y has a volume of 22.4 liters.
X mol (H2) 22L. Hence, X mol (H2) = 1 * 22 / 22.4 = 0.98 mol;
3. Determination of the number of moles of Zn based on the proportion:
0.98 mol (H2) – X mol (Zn);
-1 mol – 1 mol from here, X mol (Zn) = 0.98 * 1/1 = 0.98 mol;
Answer: in this reaction, zinc is formed in an amount of 0.98 mol.
