How many grams of H2S is needed to produce 18.00g of PbS if the H2S is reacted with an excess (unlimited) supply of Pb(CH3COO)2
How much silver iodide, AgI, in grams will dissolve in 1200 ml of pure H2O at 25 degrees Celcius when the system reaches equilibrium
Question- A solution containing 5 mL of each 4 M acetone, 1 M HCl, and 0.005M iodine is mixed with 10 mL of water. 1) What is the molarity of acetone in the reaction mixture. Hint- what is the original concentration and what is the dilution factor
Sodium has a greater first ionization energy than sulfur, and the reason for this is because Na has a greater effective nuclear charge (Zeff) than S.
From your own experience, provide an example requiring conflict management. Discuss how the incident was handled
determine the freezing point of a solution of 60.0g of glucose,C6H12O6,dissolved in 80.0g of water.
What is the percent yield of CO2 if the expected theoretical yield is 8.11·10-3 mol? Vapor pressure of water at 20.0 oC is 17.55 mmHg .
Which of the following equilibria would NOT be affected by pressure changes atconstant tempature. a.) CO(g) + 1/2O2(g) CO2(g) b.)CaCO3(s) CaO(s) + CO2(g)
When a basic solution of Cr(OH)4- ion is slowly acidified, solid Cr(OH)3 precipitates out and then redissolves in excess acid. If Cr(OH)4- exists as Cr(H2O)2(OH)4-, write equations that represent these two reactions.
Divers experience a problem known as the bends when they come up to the surface too fast. in 200-300 words can you link this phenomenon with solubility
