complete question:

When the following solutions are mixed together, what precipitate (if any) will form?

a. FeSO4 (aq) + KCl (aq)

b. Al(NO3)3 (aq) + Ba(OH)2 (aq)

c. CaCl2 (aq) + Na2SO4 (aq)

d. K2S (aq) + Ni(NO3)2 (aq)

a. Using solubility rule this reaction will not precipitate because both potential precipitates are soluble.

b. The reaction will precipitate Al(OH)3

c. The precipitate is CaSO4

d. The precipitate is  NiS

Explanation:

a. FeSO4 (aq) + KCl (aq)

Using solubility rule this reaction will not precipitate because both potential precipitates are soluble.

FeSO4 (aq) + 2KCl (aq) → FeCl(aq) + K2SO4(aq)

b. Al(NO3)3 (aq) + Ba(OH)2 (aq)

The potential precipitate are Al(OH)3 and Ba(NO3)2

2 Al(NO3)3(aq) + 3 Ba(OH)2(aq) → 2 Al(OH)3 + 3 Ba(NO3)2

Al(OH)3 is insoluble while Ba(NO3)2 is soluble . The reaction will precipitate Al(OH)3

c. CaCl2 (aq) + Na2SO4 (aq)

The potential precipitate are CaSO4  and NaCl.

CaSO4 is insoluble while NaCl is soluble . The precipitate is CaSO4

Na2SO4 + CaCl2 → CaSO4 + 2NaCl

d. K2S (aq) + Ni(NO3)2 (aq)

The potential precipitate are KNO3 and NiS.

KNO3 is soluble while NiS is insoluble . The precipitate is  NiS

K2S(aq) + Ni(NO3)2(aq) → 2 KNO3(aq) + NiS(s)

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

that tool would be a compass
