Aluminium amalgam aluminium and reduce H from water, creating aluminium hydroxide (Al(OH)) and hydrogen gas (H). The electrons from the aluminium reduce mercuric Hg ion to metallic mercury. The metallic mercury can then form an amalgam with the exposed aluminium metal. The amalgamated aluminium then is oxidized by water, converting the aluminium to aluminium hydroxide and releasing free metallic mercury. The generated mercury then cycles through these last two steps until the aluminium metal supply is exhausted. Due to the reactivity of aluminium amalgam, restrictions are placed on the use and handling of mercury in proximity with aluminium. In particular, large amounts
SAT Subject Test in Chemistry between the SAT Chemistry Test and the AP Chemistry exam, which is a more critical-thinking exam that is used not for college admissions but rather for college placement. Still, an AP course in Chemistry is sufficient preparation for the Chemistry SAT. The student is not allowed to use notes, textbooks, or a calculator on this test. The only resource a student may use is a periodic table which is provided with the test booklet. This table only provides atomic masses, atomic numbers, and symbols for each element.
