calculate the energy, in joules and calories, lost when 75.0 g of water cools from 86.4 degrees celsius to 2.1 degrees celsius
Propose a structure for an amine of formula C4H9N, which liberates a gas when treated with NaNO2 and HCl. The 13C NMR spectrum is as follows
A gas containing H2S and CO2 is bubbled through methanol at 4 degrees C. From the bottom of the tank to the top, 80% of the H2S is absorbed by the methanol.
If a sample of pure silver (Ag) contains 3.35 x 1022 atoms of iodine, how many moles of silver are in the sample?
A 100.0 mL of acetic acid solution of unknown molarity is titrated with 0.15 M NaOH solution. The titration requires 43.25 mL of the base. Determine the molarity of the acid, CH3COOH.
Radio waves travel at the speed =3.00 108 m/s(speed of light,). if Saturn is 7.9 108 km from Earth then Determine how many minutes does it take for a radio message to reach Earth from Saturn?
Lipids (fats) are esters of long chain fatty acids and glycerol. Similarly, describe the general structures of proteins and carbohydrates.
2-methyl-2-butene and 2-methyl-1-butene with Br2 in CH2Cl2
At room temperature (20), milk turns sour in about 65 hours. In a refrigerator at 3, milk can be stored three times as long before it sours. What is the activation energy of the reaction that causes the souring of milk?
If the chemist mistakenly makes 275 mL of solution instead of the 200 mL, what molar concentration of sodium nitrate will the chemist have actually prepared?
Red phosphorus is fairly stable, while white phosphorus will ignite spontaneously in air above 50 C. Determine the change in entropy for the conversion of the white form to the red form
Octahedral transition metal ions of the 4th period can display both high spin and low spin structures, while the ions of the 5th and 6th periods only show low spin structures.
The principal quantum number, n, describes the energy level of a particular orbital as a function of the distance from the center of the nucleus. Additional quantum numbers exist to quantify the other characteristics of the electron
