The reason should be explained for the more usefulness of qualitative observation than a non-quantitative observation. Whether the following observations are quantitative or not should be identified. The Sun rises in the east. A person weighs one-sixth as much on the Moon as on Earth. Ice floats on water. A hand pump cannot draw water from a well more than 34 ft. deep. Concept Introduction: An observation which can be counted / measured or results in any numeric is known as quantitative observation. For an example: number of moles, molarity etc. An observation which can be observed but can’t be measured is known as non-quantitative observation. For an example: color of sample, texture of sample etc.

Predict the organic products that form in the reaction below: H. H+ + OH H+ Y Note: You may assume you have an excess of either reactant if the reaction requires more than one of those molecules to form the products. In the drawing area below, draw the skeletal ("line") structures of the missing organic products X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Explanation Check Click and drag to start drawing a structure. G X C © 2025 McGraw Hill LLC.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. . If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T X O O лет-ле HO OH HO OH This transformation can't be done in one step.
