A chemical formula is a way that chemists describe a molecule. The formula says what atoms, and how many of each type, are in the molecule. Sometimes the formula shows how the atoms are linked, and sometimes the formula shows how the atoms are arranged in space.... Chemical energy is stored in the chemical bonds of atoms and molecules. It can only be seen when it is released in a chemical reaction. When chemical energy is released, the substance from which the energy came is often changed into an entirely different substance. Many substances and objects store

Copolymerization is an invaluable tool for "tuning" polymers so that they have the right combination of properties for an application. For example, homopolymeric polystyrene is a rigid and very brittle transparent thermoplastic with a glass transition temperature of 97°C. how to find q1 and q3 on excel The chemical formula of rust is Fe2O3. This is an oxide of iron. Formation of rust occurs when the iron is exposed longer time to the water in presence of sun and air or in absence of sun forms rust on iron. Rust is generally brownish red in colour. Given sufficient time, oxygen, and water, any iron

How To Find The Chemical Formula Of An Object
To find a chemical formula first of all you need to know the valency of a element. For examle the valency of Aluminium is 3 and Chlorine is 1. So, if you want to find out the chemical formula of Aluminium Chloride then take 3 chlorine and 1 aluminium (the valency of the other element). So, the formula is AlCl3.
