If 2 grams of zinc reacted with excess hydrochloric acid, the reaction would produce zinc chloride and hydrogen gas. The balanced chemical equation for this reaction is:
Zn + 2HCl -> ZnCl2 + H2
According to the equation, one mole of zinc reacts with 2 moles of hydrochloric acid to produce 1 mole of zinc chloride and 1 mole of hydrogen gas.
To calculate the amount of zinc chloride and hydrogen gas produced, we need to convert the mass of zinc to moles. The molar mass of zinc is 65.38 g/mol.
Number of moles of zinc = mass of zinc / molar mass of zinc
= 2 g / 65.38 g/mol
= 0.0305 mol
According to the balanced equation, the stoichiometric ratio between zinc and zinc chloride is 1:1. Therefore, the number of moles of zinc chloride produced will also be 0.0305 mol.
The stoichiometric ratio between zinc and hydrogen gas is 1:1 as well. Therefore, the number of moles of hydrogen gas produced will also be 0.0305 mol.
In conclusion, if 2 grams of zinc reacted with excess hydrochloric acid, it would produce 0.0305 moles of zinc chloride and 0.0305 moles of hydrogen gas.
