I did a lab and the sheet has 3 problems:
I need someone to look over two of them and explain the third one.
Write a balanced equation for the reaction that took place:
I got - CaCl2 + Na2CO3 ----> CaCO3 + 2NaCl
What kind of reaction took place:
Double Replacement?
And now it wants a Net Ionic Equation?
How would I write that?

1) Yes this is a double replacement reaction. The cations and anions swap.
2) Write out the total ionic equation and cancel anything that is common on both sides
Ca+2(aq) + 2Cl-(aq) + 2Na+(aq) + CO3-2(aq) -->
CaCO3(s) + 2Na+(aq) + 2Cl-(aq)
so the net ionic equation becomes:
Ca+2(aq) + CO3-2(aq) --> CaCO3(s)

Balanced reaction is good.
It is a double replacement.
To write the net ionic equation you have to break apart the equation. Assuming that none of the reactants or products are aqueous, the net ionic equation would be the same as the balanced reaction.

Ca++ + CO3= ===> CaCO3
The Na+ and Cl- are called spectator ions.

because this equation is done in water. so if one compound is soluble in water, it separate into ions like NaCl. but because CaCo3 is not soluble in water. so it remains in solid for (s).

you have to use each single element by itself in the reaction....its hard for me to put the reaction on the net so wat u can do is use the chemistry for a'levels it is a really good book
