Draw the lewis dot structure for the following diprotic acid: hooc-(ch2)4-cooh. 35.50 ml of this acid is titrated to end point with 27.10 ml of 0.970 m koh. write the balanced chemical equation for this reaction and determine the unknown concentration of the acid.

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.
