The endpoint of a titration is not exactly the same as an equivalence point. Why does the titration still work to use the endpoint?
Compute the vapor pressure at 25 °C if it is given that the density of H 2 O=0.9971 g/mL , vapor pressure of H 2 O=23.76 torr, molar mass of sucrose, = 342.3 g/mol,
Draw four different Lewis electron-dot formulas for the SeO2 molecule. (HINT: One should have two single bonds, two have a single and a double bond, and one two double bonds).
When 9 mL of a solution containing 2.5 M AlBr3 is diluted to 30 mL, a dilute solution is formed. What is the Br- concentration in 15 mL of the dilute solution?
Light travels extremely rapidly (c = 3.00×108 ). Suppose you had to travel 20 miles to work every day. If you traveled at the speed of light for the entire trip, how long would it take you to get to work (in seconds)? [1 mile = 1.61]
