Choose Physical or Chemical Change to describe the changed described. A woman visits a hairdresser and has her hair colored a darker shade of brown. The process involves bleaching( otherwise known as oxidization) her hair first, then the color is added to the bleached hair and the sealed off to keep the color in. After several weeks the hair, even though washed several times, has not changed back to the original color. Group of answer choices a) Both - bleaching the hair is chemical, adding color is physical b) Chemical c) Physical
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
