Chemistry for Kids: Chemical Mixtures

Kids learn about chemical mixtures in chemistry including solutions, alloys, suspensions, colloids, dissolving, examples, and facts. One of the main aspects of chemistry is coining different substances. Sometimes coining substances can cause a chemical reaction and bonding which creates an entirely new substance called a compound. . However, sometimes there is no chemical reaction or

Calcium, Chemical Element - structure, reaction, water, …

Chemical properties Calcium is a moderately active element. It reacts readily with oxygen to form calcium oxide (CaO): Calcium reacts with the halogens— fluorine, chlorine, bromine, iodine, and astatine, The halogens are the elements that make up Group 17 (VIIA) of the periodic table. . Calcium also reacts readily with cold water, most acids, and most nonmetals, such as sulfur and pho

Vanadium - Wikipedia

Vanadium is a chemical element with the syol V and atomic nuer 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer ( passivation) somewhat stabilizes the free metal against further oxidation .

Calcium Carbonate | Encyclopedia

2018/5/23· In its pure form, calcium carbonate is a white powder with a specific gravity of 2.71 in the calcite form or 2.93 in the aragonite form. When heated, it decomposes into calcium oxide (CaO) and carbon dioxide gas (CO 2 ). It also reacts vigorously with acids to …

Dolomite Mineral | Uses and Properties

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
