Question

zinc reacts with dilute HCl to give hydrogen gas,this hydrogen gas is used to reduce Fe3O4.So what mass of zinc is required to reduce 1kg of Fe3O4 into Fe. No spam ...........​

Answer 1

Answer:

Molar mass of Fe3O4 is 231.533 g

There are approximately 4 molecules of Fe3O4 in 1 Kg of Fe3O4

Fe3O4 + H2 = Fe + H2O

So 2*4 = 8 atoms of hydrogen is needed to reduce 1Kg of Fe3O4

and we know

Zn+2HCl→ZnCl  2  +H 2

So 1 atom of zinc produces 2 atoms of hydrogen

So here we will need 4 atoms of zinc

molar mass of zinc is 65.4

molar mass of 4 atoms of zinc is 65.4*4 = 261.6 (approx)

Hence 261.6g of zinc is needed to reduce 1kg of Fe3O4 into Fe.

Hope it helps.
