Question

2. 5 grams of aqueous calcium bromide are mixed with 5 grams of aqueous ammonium carbonate.
a.Write a balanced equation, then an ionic equation.
b.What precipitate is formed?
c.How much precipitate is formed?
d.Which reactant has some left over and how many grams are left over?

Answer 1

CaBr2 + (NH4)2CO3------> ?
now try to balance it

Answer 2

ok let me try!

Answer 3

im stuck with the parenthesis.....

Answer 4

You'll get CaCO3 and Br(NH4)2

Answer 5

Do you know how to represent the ionic reaction?

Answer 6

ok, so then the answe overall will be A...to balance the equation then right an ionic equation

Answer 7

and no i dont know how

Answer 8

But this is not an option questions, you have to solve everything...

Answer 10

ok

Answer 11

where do i go once i click on the link

Answer 12

It supposed to show a whiteboard... and i'm solving the problem there u.u

Answer 13

I guess I'll just do it here...

CaBr2 + (NH4)2 CO3 -->
(These are soluble compound so can be separated in iones)
(Ca +2) +( Br-) + (NH4 +) + (CO3 -2)--->
(This reaction will lead into:)

CaBr2 + 2(NH4)2 CO3 --> CaCO3 + 2Br(NH4)2
(Ca +2) + 2( Br-) + 2(NH4 +) + (CO3 -2)---> CaCO3 + 2(Br-) +2(NH4)

The calcium carbonate is the precipitate

Answer 14

ok.. you actually broke that down really good. I understand it. Thank you :D

Answer 15

Your welcome... ;)
