You place a balloon in a closed chamber at standard temperature and pressure (stp). you cool the chamber to half of its original temperature while leaving the pressure constant. what happens to the balloon? it stays the same volume. it decreases to one-half of its original volume. it doubles in volume. it expands to four times its original volume.

The reaction q+r2=r2q is found to be first order in r2 and

Define the kinetic molecular theory

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.
