Q. I don't understand how to balance this equation: AgNO3(aq)+ CuSO4(aq)-> AgSO4+ Cu(NO3)2(aq

A. Are you sure the equation is written correctly? Because if you think about it, the oxidation states of the compounds are: NO3 is -1 SO4 is -2 Cu is +2 Ag is +1 When you put Ag +1 and NO3 -1 together, you get: ((Ag)1)((NO3)1). The 1s cancel out, so you're left with AgNO3. When you put Cu +2 and SO4 -2 together, you get (Cu2)((SO4)2). The 2s cancel out, so you're left with CuSO4. On the RHS however: You have Ag +1 and SO4 -2 coming together, therefore, it should read: Ag2SO4. When Cu +2 and NO3 -1 come together, it is Cu(NO3)2. So, what I'm telling you is, make sure that you've written the equation correctly, otherwise, you can never balance that equation.

A. The balanced equation is 3Fe3O4 + 8Al 4Al2O3 + 9Fe Therefore, the coefficient of Fe in the correctly balanced equation is 9. The balanced equation is H2(g) + Cl2(g) 2HCl (g) Thus, the coefficient of HCl in the correctly balanced equation is 2. The balanced equation is Zn(OH)2 + 2CH3COOH Zn(CH3COO)2 + 2H2O Thus the coefficient of Zn(CH3COO)2 in the correctly balanced equation is 1 The balanced equation is 3CuSO4(aq) + 2Fe(s) Fe2(SO4)3(aq) + 3Cu(s) Thus the coefficient of CuSO4 in the correctly balanced equation is 3.

simple equation of barium chloride and copper (II) sulfate
Q. An aqueous solution of barium chloride is mixed with an aqueous solution of copper (II) sulfate. If there are 5.00 grams of barium chloride in solution how many grams of barium sulfate will precipitate. i got the equation and balanced it : BaCl2 (aq) CuSO4 (aq) >> BaSO4 (g) CuCl2 (g) Then multiplied the 5g by 233.39g (the atomic mass of BaSO4) and then i divided that number by 208.22 (the atomic mass of BaCl2) and got the answer of 5.6 grams of BaSO4, however i was wondering if I did it right? I've seen people do it moles but that confuses me and i just did mass to mass proportion. Also, i wanted to know if this is a double replacement reaction? also are my phases of matter of the products correct? thanks

Elctrolytic cell with CuSO4(aq) hooked to Cu electrodes. What are anode/cathode/total balanced rxns?
Q. It appears no rxn. occurred. No gas at either the anode of cathode. It was also acidic at beginning and ending on both electrodes. I know copper can react with itself, but if no changes are noted, how do I know which is the cathode or anode equation?
Asked by heelgrrl - Sun Apr 8 16:58:41 2007 - - 2 Answers - 0 Comments
A. At the cathode (negative terminal): Cu++ + 2e ==> Cu (Cupric ions are reduced to Cu metal, which is deposited on the cathode) At the anode: Cu - 2 e ==> Cu++ (Copper metal dissolves to give cupric ions). You can tell the anode from the cathode by weighing them before and after running current through the cell for a while. The cathode will gain weight, the anode will lose it. net reaction would be Cu ==> Cu, I think. Net result is to transfer copper metal from anode to cathode.

is this equation balanced?
Q. Zn(s) + CuSO4(aq) = ZnSO4(aq) + Cu(s)

how to write the balanced net ionic equation for these equation?
Q. Cu (s) + 4 HNO3 (aq) ---> Cu(NO3)2 (aq) +NO2 (g) +H2O (l) Cu(NO3)2 (aq) +2NaOH (aq) --> Cu(OH)2 (s, blue) + 2NaNO3 (aq) Cu(OH)2 (s, blue) + heat ---> CuO (s, black) + H2O (g) (Rxn 3) CuO (s, black) + H2SO4 (aq) ---> CuSO4 (aq, blue) + H2O (l) the above equations are chemical equations, not yet in the ionic form. I guess what i have difficulty is that i know aqueous (aq) compounds split to ions, but how about gas (g) forms? Solid compounds don't split into ions right?

A. well ill give yo ua hint start with the element containig the lasrgest subscript and when i opened this i didnt expect so many so i said "damn son" too lazy hehe but heres the last one CuO (s, black) + H2SO4 (aq) ---> CuSO4 (aq, blue) + H2O (l) already balanced hehe! and im guessing the s is for solid and the aq for aqueous but im unsure of the colors? is that what color the compound is? and out of curiosity i checked the third one and its also already balanced youre a silly goose

Can anyone help me with balancing these chem equations please! and asap!! thanks!?
Q. Cu(s) HNO3 Cu(NO3)2(aq) ---> *the arrow is under HNO3 Cu(NO3)2(aq) NaOH Cu(OH)2(s) ---> *arrow under NaOH Cu(OH)2(s) heat CuO(s) ---> *arrow under heat CuO(s) H2SO4 CuSO4(aq) ---> *arrow under H2SO4 CuSO4(aq) Zn Cu(s) --> *arrow under Zn thanks soo much!!

A. 1st equation is wrong as Cu cant replace Hydrogen from HNO3. 2nd balanced equation is: Cu(NO3)2 (aq) + 2NaOH ---> Cu(OH)2 + 2NaNO3 3rd balanced equation is Cu(OH)2(s) heat CuO(s) +H2O ---> *arrow under heat 4th equation is wrong as Cu cant replace Hydrogen from H2SO4. 5th balanced equation is: CuSO4(aq) + Zn(aq) ---> Cu(s) +ZnSO4(aq)
