The reason there is a danger in exposure to high-energy radiation (e.g., ultraviolet and X rays) is that the radiation can rupture chemical bonds. In some cases, cancer can be caused by it. A carbon-carbon single bond has a bond energy of approximately 348 kJ/mole. What wavelength of light is required to provide sufficient energy to break the C-C bond? In which region of the electromagnetic spectrum is thisCalculate the energy, in J, needed to break 1 C-C bond if it takes 348 kJ to break a mole of C-C bonds.Enter your response in scientific notation as 1.00e-10, for example.wavelength located?
Problem- It is often necessary for hospitals to measure the amount of ions in patient body fluids. Assume a patient has their urine collected over a 24-hour period. The urine specimen is diluted to 2.000 L and buffered to pH=10. A 10.00 mL sub-sam..
As protons transported into cell, ATP synthesis can be coupled to this process by ATP synthase. At 100% efficiency, under conditions above, how many proteins must be transported to synthesize one molecule of ATP?
Draw a mechanism for each reaction which explains the results. All electron movement must be indicated by arrows.
Some 2-methyl-2-butene may be produced in the reaction as a by-product. Give a mechanism for its production. (The experiment was to react t-pentyl alcohol with HCl.)
State a Lewis structure that obeys the octet rule for each of the following ions. Allocate formal charges to each atom.
A 500 ml volume of helium gas is at a pressure of 750 mm Hg and has a temperature of 30 degrees celcius. What is the volume of the same gas at STP?
a. For a weak acid with a pKa of 6.0, show how you would calculate the ratio of acid to salt at pH 5. b. Suppose you have just added 100 mL of a solution containing 0.5 mol of acetic acid per liter to 400 mL of 0.5 M NaOH. What is the final pH?
1.20 moles of a nonelectrolyte is dissolved in 1000 g of water. What is the value of the freezing point depression of this solution, given that Kf for water is 1.86 C/m?
The elements X and Y form a compound that is 33.33% X and 66.67% Y by mass. The atomic mass of X is twice that of Y.What is the empirical formula of the compound?
