Question

Potassium carbonate + copper (II) sulfate ⇒ ????

1. What are the products?
2. What are the formulas for each compound?

Answer 1

Potassium carbonates chemical formula is KCO3 (aq)
Copper (ii) sulfates chemical formula is CuSO4 (aq)
You're chemical formula when reacting these two chemicals will be
CuSO4 (aq)+ KCO3(aq) --> CuCO3 (s) + K2SO4 (aq)

Answer 2

The product from the double replacement reaction is copper carbonate and potassium sulfate- copper carbonate was precipitated out of the solution

Answer 3

Thank you so much! Do you mind helping me with a few more? @sunnnystrong

Answer 4

Sure I can try and you're welcome :)

Answer 5

Ok.. There's nine questions, but I'll go by twos.

3. What are the coefficients for each compound?
4. What are Lewis dot structures for each compound?

Answer 6

I think I know number three, but I am confused..

Answer 7

Do you think you could help me?

Answer 8

Okay. The coeffecients on each compound will be found before each compound- they are all one.

Answer 9

The coefficient in a chemical formula is the number immediately preceding the compound. It appears full size, never as a subscript or superscript.

Answer 10

Oh ok.. So the coefficients are simply one right? Because there is no other number in front of the element/compound, right? @sunnnystrong

Answer 11

Yes you're correct. For the Lewis dot structures- you need to count the valence electrons on each molecule in each compound. I'll walk you through one

Answer 12

Ok! Thank you, that would help a lot

Answer 13

I know how to make the Lewis Dot Structures, but I would like a refresher on this one. The copper part confuses me

Answer 14

The copper has a 2+ charge so you need to subtract two electrons when drawing the dot structure. Sulfate has a 2- charge so you need to add two electrons

Answer 15

Ok

Answer 16

So, what process would I use for the other compound? The Potassium Carbonate?

Answer 17

Ok, but wait. Where does the cu fit in to the structure? @sunnnystrong

Answer 18

Isn’t it all supposed to fit together to create one lewis dot structure?

Answer 19

Hello, are you still there @sunnnystrong

Answer 21

Oh ok! Thank you @triciall It is my first time using openstudy so I didnt know..
