a Choose the correct balanced equation that describes this precipitation reaction:
Naz CO3 (ag) + CaCl2 (ag) → CaCO3(s) + NaCl(aq)
Naz CO3 (ag) + CaCl2 (ag) → CaCO3(s) + 2NaCl(ag)
Naz CO3 (aq) + CaCl2 (ag) → CaCO3 (aq) + 2NACI(ag)
Naz CO3 (ag) + CaCl2 (ag) → CaCO3(s) + NaCl(ag)
Naz CO3 (ag) + CaCl2 (ag) → CaCO3 (ag) + NaCl(ag)
b Choose the correct balanced equation that describes this precipitation reaction:
Fe(C,H3O2)2 (aq) + Na, S(ag) → FeS(s) + NaC, H3 O2 (aq)
Fe(C2H3 O2)2(ag) + Na2S(aq) → FeS(aq) + NaC, H3 O2 (aq)
Fe(C, H3 O2)2 (ag) + Naz S(ag) → FeS(s) + NaC, H3 O2 (aq)
Fe(C, H3O2)2 (aq) + Naz S(ag) → FeS(aq) + 2N2C, H3 02 (aq)
Fe(C,H3O2)2 (ag) + Na2S(aq) → FeS(s) + 2NAC, H3O2 (ag)
c Choose the correct balanced equation that describes this precipitation reaction:
KOH(ag) + FeCl2(aq) → Fe(OH)2(s) + KCI(aq)
2КОН(ад) + FeCl, (aq) Fe(ОH)2(ag) + 2KCI(ag)
2КОН (ад) + FeCl, (aq) > Fe(ОH)2 (8) + 2КCI(aд)
2КОН (аq) + FeClz (aq) -> Fe(ОH)2 (8) + КKСІ(ад)
