Question

40. Write a balanced equation and a net ionic equation for combining AgNO3(aq) and Na2CO3(aq)

Answer 1

molecular equation: 2AgNO3 (aq) + Na2CO3 (aq) --> Ag2CO3 (s) + 2NaNO3 (aq)

cancel out the spectator ions that are on both sides of the equation (only if they are aqueous, don't cancel any solids, liquids and gases)

ionic equation: 2Ag(+) (aq) + CO3(2-) (aq) --> Ag2CO3 (s)

does that make sense?

Answer 2

yes it does. thank you very much. One last question..does the coefficient become a subscript usually?

Answer 3

No worries :) hmmm no it's the other way round actually. When you're writing ionic equations from molecular equations, the subscript becomes the coefficient. So for example if you want to write the ions of MgCl2, you would write... Mg(2+) + 2Cl(-)

Answer 4

oohhhh ok. thank you

Answer 5

no problem
