Through what factor would one expect the intensity of carbon tetrachloride Raman lines to increase while changing the laser source wavelength from 868.8 nm to 450.3 nm?
If a pure R isomer has a specific rotation of -133.0°, and a sample contains 64.0% of the R isomer and 36.0% of its enantiomer, what is the observed specific rotation of the mixture
When the O2 molecule is ionized to O2+, its bond becomes stronger; however, when the C2 molecule is ionized to C2+, its bond becomes weaker.
A sample of 57 grams of H 2 O with a temperature of sixteen degree celsius is combined to 260 grams of H2O at 90 degree celsius in an insulated container. Determine the final temperature after thermal equilibrium is reached?
A student sets up two reactions. Reaction 1 uses 0.290 of reactant, and Reaction 2 uses 0.580 of reactant. How many times faster is Reaction 2 compared to Reaction 1. Express your answer as a multiple of the rate for Reaction 1 to three significan..
Describe in brief the risk connected with solutions of 1M NH 3 , 1M HCl, and 1M NaOH?

With a solution in them connected by a liquid salt bridge junction filled with KNO3. In one solution you have a graphite electrode that is connected with a wire to a copper electrode in the second soution. The soution in contact with the graphite ..
select (a) best and (b) poorest electrical conductors from the following solutions and explain the reason for your choices: 0.10 M NH3, 0.10 M NaCl, 0.10 M CH3OOH(acatic acid), 0.10 M CH3CH2OH(ethanol)
Living organisms use energy from the metabolism of food to create an energy-rich molecule called adenosine triphosphate (ATP). The ATP then acts as an energy source for a variety of reactions that the living organism must carry out to survive.
For the next three problems, consider 1.0 L of a solution which is 0.3 M HC2H3O2 and 0.2 M NaC2H3O2 (Ka for HC2H3O2 = 1.8 x 10-5). Assume 2 significant figures in all of the given concentrations so that you should calculate all of the following pH..
