We have learned in this chapter that many ionic solids dissolve in water as strong electrolytes, that is, as separated ions in solution. What properties of water facilitate this process? Would you expect ionic compounds to be soluble in elemental liquids like bromine or mercury, just as they are in water? Explain.
Suppose that 35.55 mL of permanganate solution (KMnO4) is required to titrate 1.2055 grams of iron(II) ammonium sulfate hexahydrate. Calculate the concentration of the permanganate solution.
The normal boiling point of methane is -161.5 C. The specific heats of liquid and gaseous methane are 3.48 and 2.22 J/g.K, respectively. What is the final temperature of methane once the system equilibriates?
if you started a ride with ice packs that held 1600g of frozen water at 0 degree celius, and the temperature of the water at the end of the ride is 32 degree celius, How many calories of heat energy were absorb
At an underwater depth of 245ft, the pressure is 8.39atm. What should the mole percent of oxygen be in the diving gas for the partial pressure of oxygen in the mixture to be 0.21 atm, the same as in air at 1 atm?
Using a sample of water with a mass of 46.0 grams at a temperature of -58. Degree Celsius calculates how many Joules of energy (E) are necessary to heat the ice to 0 degree Celsius. Specific heat of ice= 2.1 J/g C).
How many moles of oxygen are generated during the thermal decomposition of 7.75 g of lead (IV) oxide
What is the rate law expression or chemical rate law for the disappearance of blood glucose? b. What is the rate constant (number value and units) at room temperature. c. What are the first and third half-lives. d. Graph the data to show how you s..
To make this problem easier, you may assume 65% of the methane produced comes from linoleic acid and 35% of the methane produced comes from oleic acid.
Suppose were to return your 97-106 C fraction to the empty boiling flask and redistill it, might expect it all to distill between 97-106C as it did the first time. It actually yields a few distillate in all four boiling ranges. Define why
Which one corresponds to conditions of constant volume? Explain.
