How much of a 36.0 g sample of Cs-137 will be left after 120 years?

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

what is the question here. i think you messed up.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
