Plot the activity coefficients of Na+, Ca2+, andAl3+ for ionic strengths from 0.001M (very fresh water) to 0.5M (seawater). Determine the ionic strength and TDS at which the activity coefficient corrections become important (activity coefficient less than 0.95) for monovalent, divalent, and trivalent ions.

Imagine that you’re getting ready to move to a new city. when people move, they are influenced by push factors and pull factors, and you have many reasons for your move. which of the following factors is an example of a pull factor? a. wanting to move because you’ve found a great new school somewhere new b. needing to move because there are not enough resources in your old hometown c. being forced to move because your old home is gone d. having to move because there are no jobs in your current hometown

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
