Rank the following compounds in order of their decreasing solubility in water (the one having the greatest solubility would be first)
What is the final temperature, (in oC), after a 13.5 gram piece of ice at 0oC is placed into a styrofoam cup with 124.0 grams of water initially at 76.5oC? Assume no loss or gain of heat from the surroundings.
Calculate the volume, in liters, of a 4.92 mol H2S(g) at 60 degrees C and 1.75 atm how do you do this
How many electrons could occupy a subshell with the following quantum numbers? A) n=5, l=4, B) n=2, l=0, ml=0
Determine the value of Faraday used If the electrolysis was carried out for eighty minutes with a current of four amperes flowing
When an ionic solid dissolves in water, water molecules attract the ions causing them to dissociate of come apart. The resulting dissolved ions are electrically charged particles that allow the solution to conduct electricity.
