1. It's your first day working as a lab technician at your school, and you've already made your first mistake - you were preparing bottles of three different compounds and forgot to label them. They look exactly the same! You know that each bottle hold ones of three compounds - table sugar (sucrose), table salt (sodium chloride), and benzoic acid. Using common laboratory equipment, design a series of tests you can conduct to accurately identify each compound. Be sure to discuss what the predicted result of each test would look like. (Note: tasting compounds in the lab is NEVER an option!)

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.
