Question

Which is a balanced equation for this reaction?
A.Fe + H2SO4?Fe2(SO4)3 + H2
B.2Fe + H2SO4?Fe2(SO4)3 + H2
C.Fe + 3H2SO4?Fe2(SO4)3 + 3H2
D.2Fe + 3H2SO4?Fe2(SO4)3 + 3H2

Answer 1

Heya......!!!

_____________________

Equation is : (Unbalanced)

Fe + H2SO4 -----> Fe2(SO4)3 +  H2

Now, Balancing it....

Reactant side

Fe : 1 x 2
H : 2
S : 1 x 3
O : 4 x 3

Product Side

Fe : 2
H : 2
S : 3
O : 12

Hence, We need 2Fe + 3H2SO4 ------> Fe2(SO4)3 + 3H2

This is complete balanced equation...
