From the understanding of colligative properties, how would I design an experiment to measure the freezing point of a material which freezed at -2'c using the same apparatus used in the laboratory and any chemical reagents commonly found in a chemical laboratory. Ice is the only material i have available to cool the solution
A 100.0 g sample of a metal M is burned in air to produce 103.7 g of its oxide with the formula M2O. What is the atomic mass of the metal?
In photography, unexposed silver bromide is removed from film by soaking the film in a solution of sodium thiosulfate, Na2S2O3. Silver ion forms a soluble complex with thiosulfate ion
calculate the concentration (molarity) of AgCl in a saturated solution.
If delta H for the reaction is -851.5 kJ/mol at 25'C, calculate the standard free energy change, delta G for the reaction at 25'C. Calculate the temperature at which the reaction changes from spontaneous to non-spontaneous.
Compute the final temperature of the mixture (assuming no heat loss to the surroundings). The heat capacities of H2O(s) and H2O (l) are 2.08 and 4.18 J/g · °C, respectively, enthalpy of fusion for ice = 6.02 kJ/mol.
Compression and Cooling of Nitrogen Gas. A volume of 65.0 ft^3 of N2 gas at 90°F and 29.0 psig is compressed to 75 psig and cooled to 65°F.
Will a precipitate of Cu(OH)2 form when 18.00 mL of 0.010 M NaOH is added to 1.000 L of 0.010 M CuCl2
How many grams of sodium fluoride should be added to prepare the buffer solution? Neglect the small volume change that occurs when the sodium fluoride is added.
how many grams of zinc must react with sulfuric acid in order to obtain 500mL of hydrogen at 20 deg c and 770 mm hg?
2-Methyl-1-propanol is more soluble in water than is glycerol because 2-methyl-1-propanol forms fewer hydrogen bonds with water. Glycerol is more soluble in water than is 2-methyl-1-propanol because glycerol can form multiple hydrogen bonds with wate..
One liter of a buffer solution is prepared by dissolving 0.150 mol of NaNO2 and 0.070 mol of HCl in water. What is the pH of this solution? If the solution is diluted two fold with water, what is the pH?
How much heat in kilocalories is required to melt 1.70 mol of isopropyl alcohol ? The heat of fusion and her of vaporization of isopropyl
