Question

Predict the products for the following double replacement reactions.

a.) NaOH + Fe(NO3) ->
B.) Ba (NO3)2 + H3PO4
C.) KOH + H3PO4 ->
D.) H2SO4 + Al(OH)3 ->

Answer 1

You can't change the subscript right? You can only change coefficients and subscripts remain on both sides, right?

Answer 2

In A part there must b some charge on Fe as in 2+ or 3+
B.) Ba(NO3)3+H3PO4=BaPO4+3HNO3
C.) 3KOH+H3PO4=K3PO4+3H2O
D.) 3H2SO4+2Al(OH)3=Al2(SO4)3+6H20
NOTE this '=' stands for the arrow :D

Answer 3

a.) 2NaOH + Fe(NO3)2 -> 2NaNO3 +Fe(OH)2
B.) 3Ba (NO3)2 +2 H3PO4 ->Ba3(PO4)2 + 6HNO3
C.) KOH + H3PO4 -> H2O +K3PO4
D.) 3H2SO4 + 2Al(OH)3 -> Al2(SO4)3 + 6H2O

Answer 4

I still don't get it. . .:(

Answer 5

Can you explain to me how to get what you guys got?

Answer 6

just balance the equation you will get that you have to learn i cant tell through internet

Answer 7

Alright. Thanks. :)
