If the Ka of a monoProtic weak acid is 5.3*10^6 what is the Ph of 0.15 M solution of this weak acid?
Wastewater flow in a sewer can be estimated by adding a known amount of tracer such as salt solution and measuring the salt concentration upstream and downstream of the point of addition.
Baseball reporters say that long fly balls that would have carried for home runs in July "die" in the cool air of October and are caught. The idea behind this observation is that a baseball carries better when the air is less dense. Dry air is a m..

Calculate the amount of heat needed to melt 2.00 kg of iron at its melting point (1,809 K), given that ΔHfus = 13.80 kJ/mol.
the standard reduction potential for the cu2+/cu redox couple is +.34V; that for h2o/H2, OH- at a ph of 7 is -.41V. For the electrolysis of a neutral 1.0M CuSo4 solution, write the equation for the half reaction occuring at the cathode at standard..
