A student pipetted exactly 50.00 mL of 0.1038 M HCl into a 250-mL Erlenmeyer flask
containing 0.3735 g of an antacid tablet. The solution was heated and boiled to remove any
CO2. Approximately 25 mL of water and three drops of phenolphthalein indicator was added
to the Erlenmeyer flask containing the HCl and antacid tablet. A 50 mL buret was rinsed and
filled with a 0.1017 M NaOH solution. The initial volume of the buret was read and recorded
as 2.30 mL. The NaOH solution was carefully added to the antacid/HCl solution until a
permanent very slight pink coloration was noticed. The buret was read again and recorded as
22.82 mL. Calculate the acid equivalent (g HCl/g antacid) of the antacid tablet.

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.
