The most common chemical formulas for chalk are CaCO3 (calcium carbonate) and CaO (calcium oxide). Chalk is a soft, porous sedimentary rock that is a form of limestone and is mainly composed of calcite (calcium carbonate).Continue Reading
Chalk forms under deep marine conditions, when micro-organisms called coccolithophores shed calcite plates and these tiny plates accumulate. Chalk has high resistance to weathering and can form tall cliffs where chalk ridges connect with the sea.
Chalk is used in agriculture to raise the pH in highly acidic soils. In small doses chalk can be used as an antacid. Toothpaste often contains small amounts of chalk because of its usefulness as a mild abrasive.Learn more about Chemistry
The reaction between chalk and vinegar is a neutralization reaction between calcium carbonate and acetic acid to produce water, carbon dioxide and calcium acetate. Carbon dioxide is a gas that causes the reaction to bubble.Full Answer >
According to the University of Waterloo, chemical formulas are categorized into empirical, molecular and structural formulas, which display the chemical of interest in distinct ways. Empirical formulas use the ratio of atoms to describe the chemical of interest, while the molecular formulas use the actual number of atoms in the molecule.Full Answer >
Chemical formulas are named based on the number and type of atoms in the chemical. In chemical formulas of two atoms with opposite charges, the first element is a metal and the second is a non-metal. The chemical's name is the name of the metal and the name of the non-metal, with the non-metal's name ending in the "-ide" suffix, according to Fernbank Science Center. For example, the combination of sodium and chlorine is called "sodium chloride."Full Answer >
Ferrous fumarate and ferrous sulfate are both iron-based supplements with slightly differing chemical formulas. They are both commonly taken as dietary supplements for those with iron deficiencies.Full Answer >
