Suppose the distribution coefficient of component a in a binary system is 20. according to the hill-malisoff method, the mass ratio, ma/mb, for optimal solubility precision is 20: 1. of a 10ml graduated cylinder is used in the experiment, the smaller volume contained in each tube is less than .5 ml. does this correspond to maximal volumetric precision? how do you decide how to achieve the maximal overall experimental accuracy in an experiment such as this?

Aspirin has a density of 1.40 g/cm3 what is the volume in cubic centimeters of a tablet weighing 320 mg ?

What can be added to the examples section of each circle? endothermic: ice melting into water, and a heat pack becoming warm exothermic: a glow stick glowing, and fireworks exploding endothermic: ice melting into water, and an instant ice pack turning cold exothermic: fireworks exploding, and gasoline burning endothermic: a glow stick glowing, and a heat pack becoming warm exothermic: an instant ice pack turning cold, and ice melting into water endothermic: gasoline burning, and an instant ice pack turning cold exothermic: ice melting into water, and an instant ice pack turning cold

2pos suppose an object in free fall is dropped from a building. its starting velocity is 0 m/s. ignoring the effects of air resistance, what is the speed (in m/s) of the object after falling 3 seconds? give your answer as a positive decimal without units. answer here
