When iodine enters the helical starch molecule as shown in the figure, it turns blue/black.Figure \(\Page Index\) The ribbon-like starch molecule is made up of glucose molecules, shown in the figure, linked together.Chemistry is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
The yellow marker is iodine (I), and if it turns blue/black, this indicates a counterfeit bill.
The reaction is the classic iodine test for starch.
Now that I’ve read this, I am more interested in studying chemistry at school.” – Guest Jonathan Liu Chemistry is important because it helps in exploring things which are unknown to mankind.

When people speak of "chemical free" products, they usually mean that the material is found in nature and so was not designed by a chemist, even though the molecules designed by chemists are identical.
Chemists often say 'everything is a chemical" because it is possible to understand everything in terms of molecular properties.When it's pressed, the cellulose molecules form intermolecular bonds between the oppositely charged hydrogen and oxygen atoms shown in the figure.in "natural foods" are no different than synthetic molecules made in the lab; they are both "chemicals" when understood in terms of their molecular structure or properties.My essay was awarded second place in the Country in the high school category.So I decided just to do a simple blog post about the importance of chemistry in everyday life. Chemistry is involve in the creation of all manmade objects and things.So chemistry is defined by its approach, not its subject matter.Chemistry explains or understands any subject in terms of the properties of atoms and molecules.Chemistry can help craftspeople create more functional or interesting objects, or help consumers evaluate fraudulent or unsafe products.Has a cashier ever used a yellow pen to check if your paper money is counterfeit?It's a common hobby or profession that traditionally uses a process called retting to remove all but the cellulose from plant fiber.The cellulose is beaten in a Hollander to produce wet pulp.
