You conduct an experiment to determine the concentration of ions in an unknown solution. you place 300ml inside a dialysis bag and place the bag into a beaker of water with an ion concentration of 100 ppm (parts per million). when you check the experiment an hour later, the water levels in the beaker and the dialysis bag have not changed. what can you conclude? a. the concentration of ions of the unknown solution is more than 100 ppm. b. the concentration of ions of the unknown solution is less than 100 ppm. c. not enough information to determine. d. the solutions have the same concentrations

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
