Calcium chloride - Wikipedia
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl 2.It is a white coloured crystalline solid at room temperature, and it is highly soluble in water. Melting point 772–775 C (1,422–1,427 F; 1,045–1,048 K) anhydrous 260 C (500 F
Writing and Balancing Chemical Equations | Introductory …
Extending this syolism to represent both the identities and the relative quantities of substances undergoing a chemical (or physical) change involves writing and balancing a chemical equation. Consider as an example the reaction between one methane molecule (CH 4 ) and two diatomic oxygen molecules (O 2 ) to produce one carbon dioxide molecule (CO 2 ) and two water molecules (H 2 O).

Calcium Nitrate - an overview | ScienceDirect Topics
Calcium nitrate was dissolved in 100 ml ethanol and magnetically stirred in order to obtain a clear solution. TEOS was first hydrolyzed (molar ratio TEOS:water = 1:4) and then added to the solution. This solution was agitated (magnetically stirred) for 1 h at 60 C and
Calcite - Wikipedia
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at
