KCl is the chemical formula unit of potassium chloride not a chemical equation.
When an antacid tablet dissolves in water, it is a chemical reaction. The tablet reacts with the water to neutralize excess stomach acid, which changes the chemical composition of both the tablet and the water.
Photosynthesis is the process used by plants to capture the energy that comes to us from the sun that is then held in starch or sugars.
No, changes in state are classed as physical changes as no new substance is made amd the process is easily reversed.
There are 4 visual pigments held in cone cells of the eye.

A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms that are held together in a defined spatial arrangement by chemical bonds. Chemical compounds can be molecular compounds held together by covalent bonds, salts held together by ionic bonds, inter metallic compounds held together by metallic bonds, or complexes held together by coordinate covalent bonds. Pure chemical elements are not considered chemical compounds, even if they consist of molecules which contain only multiple atoms of a single element (such as H2, S8, etc.), which are called diatomic molecules or polyatomic molecules.
All chemicals are held by chemical bond
A molecule is two or more atoms held together by covalent chemical bonds.

The metal bar above the beams, known as the front beam support, is held when carrying the triple beam balance from place to place. It is important to grip this bar securely to prevent any damage to the balance.
