GPT 3.5
The balanced chemical equation for the reaction in which hydrogen gas is produced is:
2 HCl + Zn -> ZnCl2 + H2
From the balanced equation, we can see that 2 moles of HCl produces 1 mole of H2.
To find the amount of HCl needed to produce 150 grams of H2, we first need to calculate the molar mass of H2:
1 mol of H2 = 2.016 g
Therefore, 150 grams of H2 is equal to 150 / 2.016 = 74.405 moles of H2.
Since 2 moles of HCl produces 1 mole of H2, we need half as many moles of HCl as we do of H2:
74.405 / 2 = 37.203 moles of HCl
To find the amount of HCl needed to produce 37.203 moles, we calculate the molar mass of HCl:
1 mol of HCl = 36.46 g
Therefore, the amount of HCl needed to produce 150 grams of H2 is:
37.203 moles x 36.46 g/mol = 1,357.8 grams
So, 1,357.8 grams of HCl is needed to produce 150 grams of hydrogen gas.
