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

Answer 1

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.

Answer 2

586.26 L of H2

Answer 3

Is it 0.86L of H2
I did
2.5 divided by 65.39 multiplied by 22.4
