The dimensionless henry’s law constant for trichloroethylene (tce) at 25 c is 0.4. a sealed glass vial is prepared that has an air volume of 4 ml overlying an aqueous volume of 36 ml. tce is added to the aqueous phase so that initially it has an aqueous- phase concentration of 100 ppb. after the system equilibrates, what will be the concentration (in units of mg/l) of tce in the aqueous phase?

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

Which of the following is the best name for mgcl2

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
