which works better as a solvent for benzoic acid water or the solvent pair of methanol and water.
The density of platinum is 21.5g/cm3. Platinum displays a cubic packed structure with a unit cell edge length of 392pm. Calculate the atomic mass of platinum using this data
Explain why this compound fails to react as a diels-alder diene- 2 hexagons joined in middle with a double bond in each
For a solution having 1.00 X 10^-3 equivilants/L total alkalinity (contributions from HCO3-, CO3^2-, and OH-) at [H+] = 4.69 x 10^-11, what is the percentage contribution to alkalinity from CO3^2-
Metals Covalently Bonded to Benzene, I've noticed that my book does not mention metals as a possible substituent for mono-substituted benzenes, but it doesn't begin to explain why
What is the pH of a solution made by adding 10.5 grams of sodium acetate, CH3COONa to 400 mL of 0.180 M hydrochloric acid.
A solution is prepared by mixing 250 mL of 1.00 M CH3COOH with 500 mL of 1.00 M NaCH3COO.
for 1st order problem, at 298k the rate is 3.8X10^-6M/s, and at 350k the rate is 4.2X10^-5 M/s. What is the half life at 360k?
Solid calcium oxide mixes with carbon dioxide gas. Diphosphorus pentoxide is added to water. Hydrogen sulfide gas is bubbled through a solution of silver nitrate.
