Ideally‚ the percent yield should be 100%‚ as this means that you have recovered 100% of that material. A yield over 100% would mean that the substance still has some traces of another material that is adding additional mass. Ex. The iron filings having some sand particles leftover. A yield under 100% would mean that some of the substance was not recovered‚ it could have been lost (spilled) or found in another substance (not separated completely). The percent yields may give some insight into what

| Chemistry Lab Report | Constructing Heating/Cooling Curve | | Salman Ishaq 12-E | 1/27/2013 | | BACKGROUND As energy flows from a liquid‚ its temperature drops. The entropy‚ or random ordering of its particles‚ also decreases until a specific ordering of the particles results in a phase change to a solid. If energy is being released or absorbed by a substance remaining at the same temperature‚ this is evidence that a dramatic change in entropy‚ such as a phase change‚ is occurring. Because

Causes of shifts in labor demand curve The labor demand curve shows the value of the marginal product of labor as a function of quantity of labor hired. Using this fact‚ it can be seen that the following changes shift the labor demand curve: The output price. When output price rises‚ the labor demand curve shifts to the right { more labor is demanded at each wage. When output price falls‚ less labor is demanded at each wage. Technological change causes the MPL function to change‚ generally
