Barrons SAT Subject Test Chemistry, 13th Edition

(E) These nonmetals, when they are oxides, react as acidic anhydrides with water to form acid solutions. ...

(E) The first transition metal on the Periodic Table is scandium. It is in the third period. Scandium’s electron notation shows ...

(A) The lowest-energy orbital in any atom is the 1s. The 1s orbital represents the probability distribution for the electron wh ...

(D) The type of sublevel that can hold 6 electrons is called p type. A p sublevel contains 3 degenerate orbitals, each with a c ...

(C) An s-type orbital has a spherical probability distribution for the electrons in that energy state. Energy level 3 represent ...

(C) The electron notation for sodium is 1s^2 2 s^2 2 p^6 3 s^1. Hence, the outermost electron in the sodium atom is in the 3s o ...

(T, F) Sulfur trioxide is shown by three structural formulas because each bond is “hybrid” of a single and double bond. Resonan ...

(T, F) When ΔG is negative in the Gibbs equation, the reaction is spontaneous. However, the total equation determines this, not ...

(T, T, CE) One mole of each of the substances contains 6.02 × 10^23 molecules, but their molecular masses are different. CO 2 i ...

(T, T, CE) Hydrosulfuric acid is a weak acid but is used in qualitative tests because of the distinctly colored precipitates of ...

(T, T, CE) Sodium chloride is an ionic crystal, not a molecule, and its ions are hydrated by the polar water molecules. ...

(F, F) The addition of more H 3 PO 4 causes the equilibrium to shift to the right and increase the concentration of H 3 O+ ion ...

(T, T, CE) The statement is true, and the reason is also true and explains the statement. ...

(T, F) The statement is true, but not the reason. In an equilibrium reaction, concentrations can be shown to progress like this ...

(F, T) The forward and reverse reactions are occurring at equal rates when equilibrium is reached. The reactions do not stop. T ...

(T, T, CE) Since acetylene is known to be a linear molecule with a triple bond between the two carbons, the sp orbitals along t ...

(F, F) The weakest bonds between molecules are van der Waals forces, not coordinate covalent bonds. ...

(T, T, CE) The terms dilute and concentrated merely indicate a relatively small amount of solvent and a large amount of solvent ...

(T, T) Lithium replaces any other metal in a single replacement reaction; therefore, it is the most active metal. It’s also tru ...

(F, T) The oxidation state of carbon is often +4 but not always. Carbon does have 4 valence electrons that it often relinquishe ...
