can someone please help me with this
Part A Write balanced complete ionic equation for K2SO4(aq) + Cal(aq) CaSO4(s) + KI(aq) Express your answer as a chemical equation. Identify all of the phases in your answer. ANSWER: Ca2+ (aq) + SO42-(m) CaSO4(s) Incorrect; Try Again; 4 attempts remaining Part B write balanced net ionic equation for K2SO1(aq) + Cal(aq) CaSO4(s) + KI(aq) Express your answer as a chemical equation. Identify all of the phases in your answer ANSWER: Part C write balanced complete ionic equation for NH4CI(aq) + NaOH(aq) H20(1) + NH3(g) + NaCl(aq) Express your answer as a chemical equation. Identify all of the phases in your answer ANSWER: Part D Write balanced net ionic equation for NH,CI(aq) + NaOH(aq) H2O(I) + NH,(g) + NaCl(aq) Express your answer as a chemical equation. Identify all of the phases in your answer ANSWERExplanation / Answer
A)
complete ionic equation is not the same as NET ionic equation
K2SO4 + CaI2 = CaSO4 + KI
balance species
K2SO4 + CaI2 = CaSO4 + 2KI
separate in ions
2K+(aq) + SO4-2(aq) + Ca+2(aq) + 2I-(aq) = CaSO4(s) + 2K+(aq) + 2I-(aq)
PART B
the net ionic equation contains ONLY those ions reacting, ignore spectator ions
2K+(aq) + SO4-2(aq) + Ca+2(aq) + 2I-(aq) = CaSO4(s) + 2K+(aq) + 2I-(aq)
cancel common terms
SO4-2(aq) + Ca+2(aq)= CaSO4(s)
PART C
NH4Cl + NaOH = H2O + NH3 + NaCl
balance it (it is already)
NH4Cl + NaOH = H2O + NH3 + NaCl
separate in ions
NH4+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) = H2O(l) + NH3(g) + Na+(aq) + Cl-(aq)
PART D
cancel common terms
NH4+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) = H2O(l) + NH3(g) + Na+(aq) + Cl-(aq)
then
NH4+(aq) + OH-(aq) = H2O(l) + NH3(g)
