ok well im not good at chemical equations so could some1 plz help me i need to kno wat the chemical equation for the reaction between sodium sulfate and strontium nitrate, and potassium iodide and copper(II)nitrate.

Na2SO4 + Sr(NO3)2 + KI + Cu(NO3)2 --------->

Generally, when you're first starting out, they give you the products.  If these are meant to be aqueous, can you break these compounds down into ions?  Can you then rearrange some of the ions as insoluble compounds, or gases?  What do you know about electronegativity series?  And do you recognize any red-ox reactions you've been taught before?  *whew*  Lots to do with this problem.

ok well all the question says in my lab is to write the balanced chemical equation for the reaction between sodium sulfate and strontium nitrate, and potassium iodide and copper(II)nitrate.

i tried it and came up with Na2(NO3)2 + SrSO4 + K(NO3) + CuI

is this right

[Arkcon]

Try and see if the question expects the reaction of all four, or two reactions in pairs of two.  Please check you textbook for double displacement reactions, and reduction-oxidation reactions.

[guateboy22]

its two recations in pairs and its a double displacment

ok thanx but i got the answer already it was two equations this:

Na2SO4+Sr(NO3)2+KI+Cu(NO3)2=Na2(NO3)2+SrSO4+K(NO3)+CuI

had to be plit into:

Na2SO4+Sr(NO3)2=Na2(NO3)2+SrSO4
KI+Cu(NO3)2=K(NO3)+CuI
