Consider a solution containing 0.181 m lead ions and 0.365
miron(ii) ions. the ksp for lead sulfide is 3.4 x 10^ -28 and
thatfor iron(ii) sulfide is 3.7 x 10^ -19. calculate the
[h3o+]required to reduce the concentration of lead ions to 1.0 x
10^-6 musing h2s.

Agas in a balloon at constant pressure has a volume of 160 ml at -125*c. what is its volume at 29.0*c?

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.
