Explain vanderwalls attraction. What way it affects the physical properties of non-polar molecules?
If a process is carried out at constant pressure P and the volume V of the system decreases, then is delta V negative or positive and is the work w negative, positive, or zero
A 10mL aliquot of this solution, diluted to 25mL, yielded a signal of .235 units. A second 10 mL aliquot was spiked with 10mL of 1ppm standard solution of the analyze and diluted to 25mL. The signal for the spiked sample was .502 units. What is th..
