Calculate the length in km of a row containing 1 mole of hydrogen atoms laid side to side if diameter of a hydrogen atom =.212 nm?
A basement of 14-m by 10-m by 3.0-m had a high randon content. On the day the basement was sealed off from its surroundings so that no exchange of air could take place, the partial pressure of 222Rn was observed 1.2 x 10-6 mmHg. compute the number of 222Rn isotopes (t1/2 = 3.8 d) at the start and end of 31 days.
What will be the resultant pressure when the stopcock is opened?
What is the total electronic energy
calculate (a)molality? (b)molarity of NaCl? (c) What is the mass/mass and remove the most loosely held e- from a gaseous atom in a ground state
What is the probability of populating the first excited vibrational state (n = 1) at 298 K? Does isotopic substitution affect the probability? Would the intensity of absorption peaks be affected by isotopic substitution?
Explain why the boiling point of an aqueous solution that is 1.0 m in glucose (C6H12O6) is 100.51oC whereas The boiling point of an aqueous solution that is 1.0 m in NaCl is 101.02 oC .
