What is the pH of a 0.0075 M Ba(OH)2 solution?
12.18
11.88

What is the net ionic equation for the reaction of
lead(II) nitrate with potassium iodide?
2 PbNO3(aq) + KI(aq) → 2 PbI(s) + KNO3(aq)
Pb2NO3(aq) + KI(aq) → Pb2I(s) + KNO3(aq)
Pb2+(aq) + 2 NO3-(aq) + 2 K+(aq) + 2 I-(aq) → PbI2(s) +
2 KNO3(aq)
Pb2+(aq) + 2 I-(aq) → PbI2(s)
K+(aq) + NO3-(aq) → KNO3(s)
If you sprinkled table salt into a saturated solution
of lead(II) chloride, what would happen to the
concentrations of the dissolved lead and chloride
ions?
The lead ion concentration would decrease and
the chloride concentration would increase.
The chloride concentration would increase but
the lead ion concentration would stay the same.
The table salt would not dissolve, so the lead and chloride concentrations would remain unchanged.
The lead ions would precipitate out the added chloride ions, so both the lead and chloride ion concentrations would decrease from their initial levels.
The chloride concentration would increase until
it was equal to the lead concentration, then no
more table salt would dissolve.
If a piece of dry ice (solid CO2) weighing 2.85
grams is allowed to sublimate in a tied-off

0.44 L
1.45 L
1.58 L
22.4 L

2.25 kJ
5.37 kJ
10.1 kJ
