What are different types of point defects ? Which ones are thermal defects, give the equation that gives their population.

A mixture of species of A and B is injected into a liquid chromatographic column with length of 20.0 cm. The obtained separation results are listed as follows: Species Retention time (min) Peak Width at Base (min) Non-retained 3.0 A 5.2 0.48 В 5.9 0.56 From the data, the calculated resolution Rs is smaller than 1.5 for A and B when the column length is 20.0 cm, which indicates that A and B are not separate completely. What is the new column length (unit: cm) necessary to separate the A and B species with a good resolution Rs = 1.5? Please keep your answer to one decimal place.

Calculate the percentage efficiency of extraction of phycocyanin in sample y, if the amount of phycocyanin is 57.8 mg, and the starting amount in sample x was 118.1 mg. Your answer should have one decimal place.

What is the Michaelis-Menten equation and what is it used for?

How are these equal? How would I know to match these? 25 km = 25,000 m 2.5 cm = 2.5 × 104 μm 0.25 m = 2.5 × 108 nm 2.5 mm = 2.5 × 10-6 km
