Question

calculate the volume of hydrogen produced when zinc reacted with 294 grams of sulphuric acid

Answer 1

Answer:

Reaction of zinc with sulphuric acid is follows:

Zn+H  

2

​  

SO  

4

​  

→ZnSO  

4

​  

+H  

2

​  

 

1 mole of zinc produces 1 mole of hydrogen gas.

Moles of zinc given =  

65.5

32.75

​  

=0.5

So, the amount of hydrogen produced is 0.5 mole =0.5×2=1 gram.
