Where did you get the OH- from? So the neither one of these reactions should be a percipitate?

Deep blue percipitate NH3 (aq) + CuSO4 (aq) -------> Cu(NH3)4SO4 (s) Should there be a + between the Cu(NH3)4 and SO4? brown heavy percipitate 4NaI (aq) + 2CuSO4 (aq) -------> 2CuI (s) + I2 (s) + 2Na2SO4 (aq) Is the I2 solid or aqueous? What gives the brown color?

Chem Lab "ID of Unknowns" I had to find 5 unknown solutions in a recent chem lab and now I am doing the equations, but I am not sure about two of them: Deep blue percipitate NH3 (aq) + CuSO4 (aq) -------> Cu(NH3)4 SO4 (s) brown heavy percipitate 4NaI (aq) + 2CuSO4 (aq) -------> 2CuI (s)...

Actually according to my chemistry professor My answer was correct, becasue the Cl2(g) is not aqueous so the chloides do not cancel out. Thanks Borek for the correct answer.

Please someone can you clairify this problem for me? I don't think Stevedye56 is correct on this?

Ok here is the problem: 2NaI (aq) + Cl2 (g) ----- 2NaCl (aq) + I2 (s) For the net ionic I got: 2I- (aq) + Cl2 (g) ------- 2Cl- (aq) + I2 (s) Is this correct? Most chlorides and iodides are soluble, but one states (g) and the other states (s) so does that mean they are not...

Ok I think it would be HNO3 because it is always soluble with no exceptions, so there would be no visual reaction? Does that sound legit?

yes low PH means a low number, the problem is written just like that. I can not figure anything out for it.

Yes acids contain H+ and bases contain OH, and yes I think there is a list of salts in the book.

Im not sure what you mean, I don't know what the acid is that has no reaction with all 8 of the listed reactants?

I have a question on a pre-lab that I have to do. The question is: You determine that test tube number 3 is an acid. It is colorless, odorless and has a very low pH value. You test the sample with all eight(8) reactants available and find no reaction(NR). What is the acid? Explain your...

We lit a piece of Mg so the formula is: 2Mg(s) + O2(g) HEAT-- 2MgO(s) We then dissolved this in water so it would then be: MgO(s) + H2O(l) -- Mg(OH)2(l) Next we blew into water which is: CO2(g) + H2O(l) -- H2CO3(l) Is this all correct? Should I have (Aq) after the H2CO3?

2N2O5 heat-- 4NO2 + O2 1.618 g of O2 are produced, how much NO2 in grams are produced? I got 9.30 g NO2, is that right? I used 1 mol O2 = 32 g O2, and 1 mol NO2 = 46g NO2. I first converted g O2 to Mol O2 then used the balanced equation to convert from mol O2 to mol NO2, then converted to NO2...
