Excess ice at 0 c is placed in an insulated cup containing 515 g of soft drink at 23 c. The specific heat of the drink is the same as that of water (4.184 J/g c). Some ice remains after the drink cools to 0 c. Determine the mass of ice that has melted. Assume that the heat capacity of the cup can be ignored. It takes 334 J to melt 1.00 g of ice at 0 c.
Derive an expression for the subsequent concentration of sodium chloride c in terms of c0, t, Q, and V. Make a sketch of c versus t and label the main features.
How many milliliters of an aqueous solution of 0.202 M potassium chloride is needed to obtain 11.4 grams of the salt
An electron with a mass of 9.11 x 10^-31kg and traveling at a velocity of 3.55 x 10^6 m/s has a wavelength which is measurable. what is the wavelength?
Compare the relative rate of the foward (EtOH as a substrate) and back reaction (with acetylaldehyde). Use the Michaelis-Menten equation to solve for v when ethanol is 99mM and acetylaldehyde is the substrate and its concentration is 1mM
Find the mass of the sugar (C6H12O6) required to produce 1.82 L of carbon dioxide gas at STP from the reaction?

Calculate Ka for hydrogen peroxide. you may use the reactions given on the data sheet, Kw=1.0x10^-14. Assume that hydrogen peroxide is a monoprotic acid.
In a proton nmr spectrum a methylene peak appeared at delta = 2.1 ppm when a simple 60 MHz spectrometer was used. At what frequency would this peak appear if the scale were instead given in Hertz
A 3.0 L bulb containing He at 129 mmHg is connected by a valve to a 2.0L bulb containing Ar at 110 mmHg. Calculate the partial pressure of each gas and total pressure after the valve between the flask is opened.
The Greenhouse Effect - how the sun's visible light is converted into trapped infra red light and heat, causing the planet to warm up.
