Q:

What is the common name for calcium carbonate?

A:

Calcium carbonate is an element found around the world. Because of this, there are six common names for the element: calcite, chalk, eggshells, limestone, marble and Tums.

Calcium carbonate can be found in rocks, snails, pearls, and more. Most of it is mined from quarries, and pure sources of calcium carbonate can be extracted and used for foods and pharmaceuticals. It can also be created from calcium oxide. When water is added to calcium oxide, it produces calcium hydroxide. Passing carbon dioxide through calcium hydroxide produces calcium carbonate by means of precipitation, earning it the industry name of precipitated calcium carbonate, or PCC.

    What happens when iron reacts with oxygen?

    A:

    Iron rusts when it comes in contact with oxygen and water. It rusts faster in acid rain and salty water. Both oxygen and water are necessary for rusting, which is an oxidation reaction.

    Does aluminum react with oxygen?

    A:

    Aluminum reacts with oxygen to form a layer of aluminum oxide on the outside of the metal, according to HowStuffWorks. This thin layer protects the underlying metal from corrosion caused by oxygen, water or other chemicals. Aluminum burns in oxygen with a white flame to form the trioxide aluminum (III) oxide, says WebElements. Chemists write the chemical reaction between aluminum and oxygen as: 4Al+ 3O2 = 2Al2O3.

  • Q:

    Why are Group 18 noble gases inert?

    A:

    Noble gases are inert due to their complete electron shells. Their stable atomic structure makes the energy required to add or remove an electron prohibitively high, so the noble gases do not form compounds in natural conditions.
