2 quations b. Briefly explain any FOUR (4) criteria of sanitary landfill site selection for the domestic solid waste management system. [CLO4:PLO7:C2] (6 marks) c. Soil contaminant is one of the issues in waste disposal. Describe what are soil contaminant, how it occurs and the effect of soil contaminant to human health. b. Briefly explain any FOUR (4) criteria of sanitary landfill site selection for the domestic solid waste management system. [CLO4:PLO7:C2] (6 marks) c. Soil contaminant is one of...
You have a yellow solid that melts at 41∘C and boils at 131∘C and a green solid that melts at 2320∘C. If you are told that one of them is Cr2O3 and the other is OsO4, which one do you expect to be the yellow solid Cr2O3 OsO4
An aqueous solution is saturated with both a solid and a gas at 5 ∘C. What is likely to happen if the solution is heated to 85 ∘C? Hints An aqueous solution is saturated with both a solid and a gas at 5 . What is likely to happen if the solution is heated to 85 ? A.) Some gas will bubble out of solution and more solid will dissolve. B.) Some gas will bubble out of the solution and...
A solid sphere, a solid disk, and a thin hoop are all released from rest at the top of the incline (h0 = 20.0 cm). a) Without doing any calculations, decide which object would be spinning the fastest when it gets to the bottom. Explain b) Again, without doing any calculations, decide which object would get to the bottom first. Hint: which one has greater translational speed? Think CoE! c) Assuming all objects are rolling without slipping, have a mass...

Does any solid silver chromate form when 2.7x10-5 g of silver nitrate is dissolved in 15.0ml of 4.0x10-4 M potassium chromate?
At 900 K, the reaction CO2 (g) + C (solid) = 2 CO (g) comes to equilibrium. For the standard states shown above, and a standard state pressure of 1 atm for the gas phase, the equilibrium constant K = 0.178. a. Determine the mole fraction of CO, yCO, at equilibrium at 10 atm assuming the gas phase is an ideal gas. b. Suppose at this pressure, it is desired to not produce any solid C. What is the maximum...
Does any solid PbCI_2 form when 25 mg of NaCI is dissolved in 0.250 L of 0.12 M Pb(NO_3)_2 ? K_sp for PbCI_2 = 17 times 10^-5 A simple yes or no receives no credit. Show clearly how you determined your answer.
