Astudent performed the experiment described in your lab handout. he used 4.972 grams of hydrogen peroxide and roughly 10 mls of 1.0 m ki and produced a 71.7 ml volume of gas. the experiment was preformed at 27oc. the atmospheric pressure was 761.4 torr
what was the partial pressure (in torr) of water vapor in the 100 ml cylinder? what was the partial pressure (in torr) of o2 in the 100 ml cylinder? what was the partial pressure (in atm) of o2 in the 100 ml cylinder? how many moles of o2 were produced? how many moles of h2o2 were consumed? what mass of h2o2 was consumed? what was the % by mass of h2o2 in the original solution?

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
