A theoretical yield is equivalent to a percent yield of 100. In practice, it is very rare to achieve 100 yield from a reaction due to a wide range of outside factors 1.7mol
when it is exposed to heat it melts
Used in printing, usually an aluminum sheet with a photosensitive coating which can develop an image after being exposed to the appropriate wavelengths through a negative or positive film.a what about limestone plates of the 19th centuary artist?
Aluminum in general is a very reactive metal. So reactive that once it is forged and exposed to the air it reacts with the oxygen in the air to produce a thin layer of aluminum oxide. This thin layer of aluminum oxide prevents the aluminum from further oxidation or rusting. The same thing happens when aluminum is exposed to water. Believe it or not aluminum exposed to water produces hydrogen. The amount of hydrogen produced is so small it is undetectable because once the aluminum is exposed to the water it forms a shield of aluminum oxide preventing further reaction. A way around this reaction block is by making an alloy of gallium and aluminum. Gallium metal is a liquid metal just above room temperature. When gallium is combined with aluminum it doesn't allow the aluminum to form the protective layer of aluminum oxide when exposed to water or oxygen in the air. Allowing the aluminum to continuously react with the water and produce hydrogen gas. I hope this answered your question.
Aluminum
No, aluminum is not heavier when it is corroded. Corrosion is a chemical reaction that occurs on the surface of metals, including aluminum, when exposed to moisture and oxygen. It forms a layer of aluminum oxide, which is actually lighter than aluminum itself.
Scientifically speaking, they are a mixture. The aluminum that is visible and is exposed to the air has oxidized and created a very small layer of Aluminum Oxide (Al2O3).
