Suppose you have a mixture of solid potassium chloride and magnesium carbonate. The physical and chemical properties of potassium chloride are similar to those of sodium chloride, and the properties of magnesium carbonate are similar to those of calcium carbonate. a.draw a ﬂowchart that shows how you would separate and recover the two components of this mixture.

Heat effects of chemical or physical processes can be measured in a calorimeter.

Can someone please paraphrase this to me.... if possible. Heat effects of chemical or physical processes can be measured in a calorimeter. Instruments of widely varying designs are employed to accommodate the large range of experimental conditions encountered. For instance, the heat effects to be measured may range from milliJoules to milliliter, quantities involved from fractions of milliliters to hundreds of milliliters and from milligrams to grams, operating temperatures from below liquid helium temperature (4.2 K) to 2000o C, and...

Discuss the purpose and at the same time demonstrate how you perform physical examination of head, face, eyes, ears, nose, mouth, throat, neck vessel, breast, regional lymphatics, thorax and lungs, heart, abdomen, and peripheral vascular system in order. Your discussion should includes the reason why we perform physical exam in each system or what abnormalities do we have to assess during physical examination of those systems.

The values of certain types of collectibles can often fluctuate greatly over time. Suppose that the value of a particular limited edition figurine is found to be able to be modeled by the function ?(?) = −0.01?4 + 0.47?3 − 7.96?2 + 49.18? + 65 for 0 ≤ ? ≤ 20 where ?(?) is in dollars, t is the number of years after the figurine was released, and ? = 0 corresponds to the year 1999. a) What was the...
