2. given the following experimental data, calculate the molarity and the pka of the acid analyte (ha) in the titration, if the balance neutralization reaction is ha + naoh à naa + h2o. a ph reading of 3.65 was obtained when 13.0 ml of 0.413 m naoh was added to the 25.0 ml analyte. the endpoint was achieved when 31.25 ml of naoh had been added.

What are the resulting coefficients when you balance the chemical equation for the combustion of ethane, c2h6? in this reaction, ethane is burned in the presence of oxygen (o2) to form carbon dioxide (co2) and water (h2o). (g)+(g)→(g)+(g)

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.
