Draw Newman Projections to show the different conformers of 2- chloropentane, focusing on the C2-C3 bond. Show all six conformers.
Titanium(6.94x10^-19 J and silicon (7.77x10-^19 J) surfaces are irradiated with UV radiation with a wavelength of 245 nm. what is the wavelength of the electrons emitted by the titanium surface
a mixture of methane and ethane is stored in a container at 294 mmHg. The gases are burned in air to form co2 and h2o. if the pressure of co2 is 357 mmhg measured at the same temperature and volume as the original mixture, calculate the mole fract..
calculate script edeg values for the following cells. which reactions are spontaneous as written under standard
Why do solutions of iodide ion in water appear yellow when I- is oxidized to I2 by a suitable oxidizing agent, while solutions of I- in CCl4 or CHCl2 appear violet when the same oxidationis done?
Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating. Suppose that a can contains a residual amount of gas at a pressure of 770 mmHg and a temperature of 30 C
When a mixture of 10.0 g of C2H2 and 10.0 g of O2 is ignited, the resultant combustion reacion produces CO2 and H2O. How many grams of C2H2, O2, CO2
The CNOG ion is very unstable and is the reason why the mercuric compound is explosive. On the other hand, mercury cyanate, Hg(NCO)2, is not explosive. The cyanate ion (NCOG) is a stable ion. Use resonance structures and electronegativities to exp..
ag has a density 10.5 g cm3.a graduated cylinder has 28.0 ml of h2o. determine the new water level after 35.6 grams of
If you mix 10 mL of a 0.1 M HCl solution with 8 mL of a 0.2 M NaOH solution, what will be the resulting pH? If a weak acid, HA, is 3% dissociated in a 0.25 M solution, calculate the Ka and the pH of the solution.
A gas occupying 28mL at standard conditions is heated to 18C while the pressure is reduced to 0.98221 atm. What is the new volume occupied by the gas? Answer in units of mL.
Calculate the pH of the solution which results from adding 38.54 mL of 0.1012 M KOH to the cyanic acid/cyanate buffer of the previous problem(*). You must show appropriate chemical equations for full credit.
Suppose that 1.252 g of impure barium hydroxide is dissolved in enough water to pro- duce 213.4 mL of solution and that 64.3 mL of this solution is titrated to the stoichiometric point with 29.5 mL of 0.0318 M HCl(aq). What is the percentage purit..
