How many grams of magnesium may be formed by the passage of 76.0 amps for 8.03 hours through an electrolytic cell that contains a molten magnesium salt.
What is the molar mass of X if 0.85g of X depresses the freezing point of 100g of benzene by 0.47Cdegrees?
Because Ions are more strongly attracted in an ionic compound than molecules are attracted in molecular compounds
The normal melting point of napthalene is 353.05K. When the solution becomes saturated at 310k, we expect the mole fraction of napthalene in the saturated solution.
NaCl is added to 33.4ml of 0,327M AgNO3(silver nitrate). What would be the concentration of each of the ions(ie Ag+, NO3- Na+ and Cl-) in the reaction mixture after the reaction.
Given the following experimental data, find the rate law and the rate constant for the reaction:
what will the maximum temperature reached by the resulting solution? [Assume that there is no heat loss to the container, that the specific heat of the final solution is 4.18 J/g*C, and the density of the final solution is that of water.]
Calculate delta S0 for the following processes: a.) Heating 1 mol of benzene(liquid) from 298K to 353 K at 1 bar pressure, neglecting any T- dependence of Cp.
Calculate the hydrogen Ion concentration, in moles per liter, for solutions with each of the following pH values.
What is the molarity of C6H12O6 in an aqueous solution that is prepared by dissolving a 20.95 g sample of impure C6H12O6 in water to make 1,450 mL of solution. Assume that the sample is 93% C6H12O6 by mass. Enter your answer in mol/L, accurate to ..
A new soft drink on the market is prominently labeled as "caffeine-free". Based on the nature of complaints filed by several consumers, it appears that the "caffeine-free" claim might actually be fraudulent.
