The Kingston Steam Plant burns 14,000 tons of coal each day and generates 1010 kilowatts-hours of electricity each year (enough for 700,000 homes). Coal is primarily carbon which undergoes combustion in the following reaction:
C(s) + O2 (g) -> CO2(g)
How many grams of oxygen is required for the combustion of 1 day's coal?How much carbon dioxide is produced each day?
Calculate the expected pH of the buffer after the addition of 1.0 mL of 1 M HCl. Remember that you are using 50 ml of the buffer so be sure to calculate the number of moles of acetic acid
How many milliliters of 0.20M NaOH do you need to neutralize 40.0 ml of 0.12M acetic acid?
Use an orbital diagram to draw the molecular orbital for H2+. Do you predict this molecule will be stable? Explain your logic.
How much energy in J is needed to convert 48 g of liquid ethanol at 67 oC to vapor at 97oC. You might need to know that: mp = -114 oC and bp = 78oC The heat of fusion is 4.6 kJ/mol and the heat of vaporization is 46.0 kJ/mol. Finally, the specific..
The Born-Haber cycle is a series of steps that represent the formation of an ionic compound from a metal and a nonmetal. For example, the steps in a Born-Haber cycle for the formation of NaCl(s) consist of sublimation of the metal Na atom
what is the chemical formula of a gas if it has a pressure of 680 torr and a density of 1.60 g/L at 27 degrees C.
Look at the table of polyatomic ions and determine what happens to the charge on the polyatomic ion, phosphate when an H+ is added to the formula. What is the new name
Confirm that the z-component of orbital angular momentum is a basis for an irreducible representation of A2 symmetry in C3v.
Calculate the heat released when 2.57 L of Cl2(g) with a density of 1.88 g/L reacts with an excess of sodium metal at 25°C and 1 atm to form sodium chloride.
Hydration of alkynes (via oxymercuration) gives good yields of single compounds only with symmetrical or terminal alkynes. Draw the major organic product(s) formed
This acidity has affected many lakes in northern Europe, the northern United States, and Canada, reducing fish populations and affecting other parts of the ecological network within the lakes and surrounding forests
