A4.00 ml aliquot of a 0.15 m hcl solution is diluted to a final volume of 25.00 ml. what is the molarity of this first dilution solution? then a second dilution was made by taking 7.50 ml of the first dilution and diluting it to 50.00 ml. what is the molarity of this second dilution?

After cloud droplets form, what must happen to them for precipitation to occur?

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
