Description
This listing features a full-page exam for a unit about atomic structure, atomic symbols, atomic history and dimensional analysis in chemistry. The first page is a blend of multiple choice, fill in the blank, and problem question styles.
Students need to: know Rutherford’s, Dalton’s, Thomson’s contributions to the field of chemistry, write the nuclear and hyphen notation of an atom, identify carbon dioxide as an element, compound, mixture, and/or pure substance, identify the number of protons, neutrons, and electrons in a stated isotope of an atom, explain how isotopes differ from one another, identify the method used to calculate the average atomic mass of an atom, match stated examples/definitions to the correct law (Definite proportions, multiple proportions, and/or conservation of mass), calculate the percent by mass of an atom in a compound, and calculate the molar mass of an unknown element given the empirical formula of the compound (X2Y5), the sample mass of the compound, and the molar mass of the other element.
The second page is six-dimensional analysis problems where students calculate mass from moles, mass from atoms/molecules, moles from mass, atoms/molecules from mass, atoms/molecules from moles, and moles from atoms/molecules.
I provided a complete key with the answers in red font. I mapped out the calculations to the answers for each problem.
This PDF document will become editable upon conversion to Microsoft Word with an Adobe Acrobat DC Reader app.
I offer dozens of quality field-tested, innovative, practical, and user-friendly products for several fields of science - biology, chemistry, field ecology, physical science, earth science, space science and human anatomy and physiology.
