Question
Zn+ 2HCl -> ZnCL2+h2
what volume of hydrogen at stp is produced when 2.5 of zinc react with an excess of hydrochloric acid
what volume of hydrogen at stp is produced when 2.5 of zinc react with an excess of hydrochloric acid
Answers
Balance the equation.
Convert 2.5 g Zn to mols. mols = g/molar mass.
Using the coefficients in the balanced equation, convert mols Zn to mols H2.
Convert mols H2 to volume H2 remembering that mols x 22.4 L/mol at stp = L.
Post your work if you get stuck.

586.26 L of H2
Is it 0.86L of H2
