The Significance of Chemical Changes in Science

A chemical change is any change that results in the formation of new chemical substances, In the following experiment, a solution that begins with copper nitrate II will undergo a series of chemical changes. Examples of evidence for a chemical change include temperature change, color change, precipitate formation, and gas given offl During a change of temperature, a solution is exothermic meaning there is an increase in the speed of molecules. Exothermic is the taking in of energy When a change of color occurs, there is an increase or decrease of potential energy stored in new bonds The same applies to when a precipitate forms as welll The amount of kinetic energy increases in the atom when a gas is given off.

A milk carton souring can be identified as a chemical change because pugnant lactic acid is produced. Another real life example of chemical change is a car engine burning off gasoline.

The products of that reaction include water vapor and carbon dioxide Chemical reactions are very important to everyday life.

Many substances people use result from chemical change. Chemical reactions also provide scientists with a keen understanding of the properties of matters The properties discovered can contribute to determine an unknown specimen or to predict the types of matter that react with each others By witnessing chemical reactions, scientists are able to explain how the natural world works. Chemical reactions convert food to fuel for your body to use, causes food to change its condition when cooked, makes soap remove filth, and so on If chemical reactions didn’t occur, nothing would change.
