Calculate how many mL of 6M HCl are needed to prepare 100mL HCl solution with a concentration of ~1M.
A scientist has a sample of gas that was collected several days earlier. The sample has a volume of 392 cm3 at a pressure of 0.987 atm and a temperature of 21°C.
Claisen reactions use a stoichiometric amount of base and do not polymerize, unlike aldol reactions that use a catalytic amount of base and can polymerize.
Determine the numbers of moles of S8 that are required to make 0.600 moles of SF4.
Adding magnesium ribbon (about .5g) in a solvent of 100mL of HCl acid in a polysterne cup as my calorimeter. my question is why and how would my calculated anthalpy of reaction be inaccurate if:
What amount of HCl gas must be added to 1.00 L of a buffer solution that contains [acetic acid] =2.0 M and [acetate]=1.0 M in order to produce a solution with pH =4.24
What is the freezing point of this solution? The Kf for water is 1.86 C/m and the density of ethylese glycol is 1.1135 g/mL. Consider if the solute is an electrolyte or a non electrolyte.
derive Raoul's law using the chemical potentials of the constituents that make up the mixture of the solution.
Would MS help you with either of these problems? If yes, explain how. a) differentiating 1-pentyne from 2-pentyne
(a) What is the molecular weight of the drug? (b) What is the boiling point of the solution? (c) What is the osmotic pressure of the solution?
Palladium crystallizes in a face-centered cubic unit cell. Its density is 12.0 g/cm^3 at 27 degrees C. Calculate the atomic radius of Pd.
Osmosis occurs when the solvent molecules move from a solution of higher solute concentration to a solution of lower solute concentration.
An unknown organic compound is mixed with 0.5190 g of naphthalene crystals to give a mixture having a total mass of 0.5959 g. The mixture is heated until the naphthalene melts and the unknown substance dissolves.
