The chlorination of 2-methylbutane can increase its reactivity and change its chemical properties by replacing hydrogen atoms with chlorine atoms. This can lead to the formation of new compounds with different properties and potential for reactions.
Chemical activity decreases down Group 7 (halogens) as atomic size increases. Chlorine, a Group 7 element, is used for water purification, manufacturing of plastics and pesticides, and in the production of bleach and disinfectants due to its strong oxidizing properties.
What compounds Change the properties of glass?
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed.
Vanilla extract is a chemical change. It is produced by extracting the compounds from vanilla beans using a solvent and alcohol, resulting in the formation of new chemical compounds with different properties than the original vanilla beans.
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
It makes it stiffer and even more flame retardent.
The production of chlorine gas when calcium chloride is heated to decomposition is a chemical change. This is because a new substance (chlorine gas) with different chemical properties is formed as a result of a chemical reaction taking place between the calcium chloride and heat.
A chemical change is one that creates compounds (products) that are different from the reactants. A physical change only alters the form or phase of the existing substances, not their chemical properties.
Because there is no chemical reaction, the properties of the elements and compounds do not change when they form a mixture.

Yes, combining sodium metal with chlorine gas to form sodium chloride is a chemical change. This process involves the formation of new chemical bonds and the creation of a new substance with different properties than the reactants.
