Question

a) CuSO4(aq) Zn(NO3)2(aq)=???? b)Na2CO3(aq) NH4Cl(aq)=???? c) NaOH(aq) AgNO3(aq)=????? d)FeCl3 NaOH(aq)=???????? e) CuSO4(aq) NaOH(aq)=?????

Answer 1

since the plus sign doesn't appear, i'll use ~.

a) CuSO4(aq) Zn(NO3)2(aq)=????

= CuSO4(aq) ~ Zn(NO3)2(aq) = Cu(NO3)2 ~ ZnSO4

b)Na2CO3(aq) NH4Cl(aq)=????

= Na2CO3(aq) ~ 2NH4Cl(aq) = (NH4)2CO3 ~ 2NaCl

c) NaOH(aq) AgNO3(aq)=?????

NaOH(aq) AgNO3(aq)= NaNO3 ~ AgOH (not sure about this.)

d)FeCl3 NaOH(aq)=????????

FeCl3 ~ 3NaOH(aq)= Fe(OH)3 ~ 3NaCl

e) CuSO4(aq) NaOH(aq)=?????

CuSO4(aq) ~ 2NaOH(aq)= Na2SO4 ~ Cu(OH)2

Answer 2

) CuSO4(aq) Zn(NO3)2(aq)=> no reaction

b)Na2CO3(aq) NH4Cl(aq)= no reaction

c) 1NaOH(aq)  & 1AgNO3(aq)=> 1NaNO3(aq) & 1AgOH(s)

d)1 FeCl3  & 3 NaOH(aq)=> Fe)OH)3 (s)  & 3 NaCl (aq)

e) 1CuSO4(aq)  & 2 NaOH(aq)= 1 Cu(OH)2 (s) & 1 Na2SO4 (aq)
