The volume between the 50.00 mL mark and the valve of a buret is 6.19 mL. The buret reading of an upside-down buret containing a pocket of hydrogen gas is 32.17 mL. What is the total volume of hydrogen in the buret?

The element that has the greatest electronegativity is

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.
