A good definition of chemistry is: the science that seeks to understand what living organisms do by studying the molecules that make up the organism. the science that seeks to understand what matter does by studying what atoms and molecules do. the science that seeks to understand the interactions of molecules for the sake of advancing human control over nature. the science that seeks to understand what the universe does by studying interactions of molecules with atoms. none of the above
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.
