What is the boiling point of a solution produced by adding 510g of cane sugar (molar mass 342.3g/mol ) to 2.1kg of water. For each mole of nonvolatile solute, the boiling point of 1kg of water is raised 0.51 degrees celsius.
Predict the sign of delta S_system for the following processes a) molten Fe solidifies b) LiCl_(s) is formed formed from Li_(s) and Cl2_(g)
A solution composed of 20.00 g C2H5OH in 60.00 g CCl4 has a density of 1.280 g/mL. Calculate the molarity of C2H5OH in the solution.
Consider the acid-catalyzed cleavage of propylene oxide with 1-propanol. Provide abbreviated structural formulas for the protonated epoxide substrate and of 1-propanol
the S for the system is predicted to be negative, so therefore the ?S for the surroundings must be positive to a greater extent so that the the net S for the universe is positive
The Group 5A elements N,P,As have lower (less negative) electron affinities than most of the Group 4A or Group 6A elements because N,P,As have half-filled subshells.
The half-life of Plutonium-239 is 24,000 years. If 10 gms are present now, how long will it take until only 10% of the original sample remains? Round your answer to the nearest 10,000th.
a 355 ml container holds .146g of ne and an unknown amount of ar at 35 degrees c and a total pressure of 26 mmhg.
2SO2(g) + O2(g) 2SO3(g) Suppose the volume of this system is compressed to one-half its initial volume and then equilibrium is reestablished.
MnSO4 (aq) is converted to MnO2(s) in a basic medium as oxygen gas is converted to hydroxide ion. In this case, is the sulfate ion a spectator ion
The use of high salts, e.g. "salting out" is a common technique used during protein purification. Describe the chemical process underlying this method.
calculate the number of tons of carbon dioxide and sulfur dioxide produced by the plant during the year. (b) If 55% of SO2 could be removed by reaction with powdered CaO to form CaSO3, how many tons of CaSO3 would be produced.
