Molcular Compelet Ionic and net Ionic equation i will post 1500 point here and another 1500 in another

i need u to show me which are (aq) (s) (g) + balance it and compelete it before doing the steps

this is a percipitiation or not percipitation .

guys its due in 3 hours help me

Explanation / Answer

1) CuBr2 + CaCl2 = CuCl2 + CaBr2

2) K2CrO4(aq) + CaCl2(aq) ? 2 KCl(aq) + CaCrO4(s)

3)CaCl2 (aq) + Ag2SO4 = 2 AgCl (s) + CaSO4 (s)

4) 2NaOH(aq)+CaCl2(aq)=2NaCl(aq)+Ca(OH)2(aq)

5) CuBr2(aq) + K2CrO4(aq) ? CuCrO4(s) + KBr(aq)

6)CuBr2 + Ag2SO4 = CuSO4 + 2 AgBr

7) CuBr2(aq) + 2 NaOH(aq) --> Cu(OH)2(s) + 2NaBr(aq)

9) CU(NO3)2 + SRBR2 = CUBR2 + SR(NO3)2

10) Ag2SO4 (s) + K2CrO4 (aq) = Ag2CrO4 (s) + K2SO4(aq)

11) Sr(NO3)2(aq)+K2CrO4(aq) = SrCrO4(s)+2KNO3(aq)

12) Ag2SO4(s) + KNO3(aq) => 2 AgNO3(aq) + K2SO4(aq)

13 ) Ag2SO4(s) + Sr(NO3)2(aq) = Ag(NO3)(aq) + SrSO4(s)

14) NaOH(aq) + Sr(NO3)2(aq) ---> NaNO3(aq) + Sr(OH)2(s)

all (s) means precipitated. question 8 and 9 were same
