what is the rule for compounds containing nitrates
always soluble, aqueous
what is the formula for molarity and units (the triangle thing)
triangle thing :)
what are we looking for in a redox reaction?
Transfer of electrons:
- Loss of electrons, Oxidation
- Gain of electrons, Reduction
From the combined gas law, show how you can get all other gas laws
P1V1/ T1 = P2V2 / T2

Mercury (II) nitrate
Hg(NO3)2
soluble
Lead (II) nitrate is used in the manufacturing of matches and special explosives. If 721 mL of a 0.122 M Lead (II) nitrate solution is mixed with 529 mL of a 0.33 M potassium iodide solution, how many grams of precipitate can be produces?
37.2 g PbI2
40.24 g
Give Redox numbers for:

Whats a leprechauns favorite time of day?
Golden hour
Barium sulfate
Ba(SO4)
insoluble
If a chemist dissolves 84.5 g of calcium chloride in 765.3 mL of water, what would would be the molar concentration of chloride ions?
1.98 M Cl
Copper metal reacts with aqueous silver nitrate to produce silver metal and copper (II) nitrate. Give oxidation numbers and write half reactions.
Cu: 0, Ag: +1, N:+5, O:-2,
Ag: 0, Cu: +2, N:+5, O: -2
Oxidized Cu 0 --> Cu +2 + 2e-
Reduced: 2Ag +2e- --> 2Ag 0
Calculate the volume of 1.89 x 1023 molecules of nitrogen gas trapped in a container at a pressure of 325.4 torr and a temperature of 198 F

Suppose 15 g of nickel (II) bromide is dissolved in of an aqueous solution of 50 mL of 1.6 M potassium carbonate. Calculate the final molarity of bromide anion in the solution. You can assume the volume of the solution doesnt change when the nickel (II) bromide ion is dissolved in it
2.76 M Br -
Give a real life example of redox

Convert the following:
2.74 atm --> X mmHg
X mmHg ---> Y Torr
Y Torr ---> Z kPa
Z kPa ---> :) PSI
X mmHg: 2,082.4
Y Torr: 2,082.4
Z kPa: 277.63
:) PSI: 40.26

Write the total ionic and net ionic reaction for:
Barium nitrate reacts with Sodium sulfate
net:
Ba+2(aq) + SO4-2(aq) ---> BaSO4 (s)
Assume 215 mL of 1.45 M cadmium sulfate solution and a 48.1 mL solution containing an unknown concentration of potassium sulfide are mixed in a beaker.
Provide total ionic and net ionic equations for the reaction that takes place
If the mixing produces 53.2 g of precipitate what is the concentration of the potassium sulfide solution producing this result
Cd+2 (aq) + S-2 (aq) --> CdS (s)
7.7 M potassium sulfide
Define OIL RIG
Oxidation is loss of electrons, becoming more positive
Reduction is gain of electrons, becoming more negative
A lightbulb contains 0.0758 g of argon gas with a pressure of 98 Torr at 27.0 C. The light bulb is then turned on and the temperature eventually rises to 290 C. Calculate the final pressure inside the lightbulb.
P= 0.24 atm
