Classify each of the following molecules as polar or nonpolar: a) GeH4; b) I2; c) CF3Cl; d) PCl3; e) BCl3; f) SCl2.
The activity of a radioactive sample is the number of nuclear disintegrations per second, which is equal to the first-order rate constant times the number of radio-active nuclei present.
Ascorbic acid (Vitamin C, H2C6H6O6) is a diprotic acid. In a laboratory exercise, a vitamin C tablet was analyzed by titration using 0.125 M NaOH(aq). On the average, it required 29.5 mL of the base to neutralize the acid in the one tablet. How ma..
