1- If 122 g of Hg2Cl2 is reacted with excess ammonia, what is the expected yield, in moles and grams, of elemental mercury? (show your calculation)
2- If you have an aqueous solution containing only one of the silver group cations, what single reagent could you add to decide which one you had? Explain.
What volume of gold would be equal in mass to a piece of copper with a volume of 140.0 mL. The density of gold is 19.3 g/mL; density of copper is 8.96 g/mL
A thin plate of copper is suspended in seawater. If the corrosion rate is 0.4 mpy (mils per year) and the plate is a square of dimension 4.0 in. per side, how much weight loss (in mg) is expected in 18 days
By Solving this problem student is able to understand how to calculate theoretical and percent yields in an experiment - determine theoretical and percent yields for this experiment.
What are the two steps in the Experimental Procedures that are incorporated to reduce the loss of the lead (2) iodide precipitate. Identify the steps in the procedure and the reason for each step.
The reading on a mercury manometer at 25 deg C (open to the atmosphere at one end) is 56.38 cm. The local acceleration of gravity is 9.832 m s-2.
calculate the pH of a buffer solution made by adding 10.0g of anhydrous sodium acetate (NaC2H3O2) to 100 ml of 0.100M acetic acid. sume there is no change in volume on adding the salt to the acid.

Powdered coal ( essentially pure C ) is reacted with excess water to make a mixture of CO,CO2 and H2 The reaction is desired reaction ,CO2 is an undesired waste product. This gas mixture from the reactions of coal with water is further reacted ove..
The combustion of 2.150 mmol of X caused the temperature of a bomb calorimter to rise from 23.650 oC to 26.350 oC. Assume T = 25.000 oC, Hcomb = -2480 kJ/mol, and ng = -4 mol gas/mol X for the combustion and determine the heat capacity of the calo..
Calibration of a glass electrode gave a reading of 148.7 mV with 0.05 m potassium dihydrogen citrate buffer standard (pH = 3.766) and a reading of -167.4 mV with 0.01 m borax buffer standard (pH = 9.139), both measured at 30°C.
