The number of atoms of the isotope which will be more in a sample of copper among two isotopes of copper ( 29 63 Cu and 29 65 Cu ) should be determined. Concept introduction: Most of the elements have two or more than two isotopes. Isotopes are the atoms of the same element with different mass numbers due to presence of different number of neutrons in their nuclei. The relative abundance of isotopes varies in nature. For this reason, the atomic mass of an element is calculated by multiplying the mass of each isotope by its percentage abundance value and then adding all those values for all isotopes of the element.

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.
