How much hydrogen will be released when 130 g of zinc interacts with water?
| August 16, 2021 | education
We write down the reaction equation.
Zn + 2H2O = Zn (OH) 2 + H2.
Determine the amount of zinc. To do this, you must first calculate the molar mass of zinc.
M (Zn) = 65 g / mol.
n (Zn) = 130/65 = 2 mol.
Next, we determine the amount of hydrogen substance and calculate the volume of hydrogen.
2 mol – x mol.
1 mol – 1 mol.
X = 2 mol.
V = 2 * 22.4 = 44.8 liters.
Answer: the volume is 44.8 liters.
