Suppose you accidentally drop a glass bowl full of sugar onto the floor, causing the bowl to shatter into pieces. Which of the procedures would be the most effective way to separate the sugar from the tiny pieces of glass? Collect all of the sugar and glass pieces into a pot and heat the mixture to melt the sugar. Then, pour the liquid sugar through a filter to separate the glass from the sugar.   Collect all of the sugar and glass pieces into a bucket of water. Allow the water to dissolve the sugar, then remove the water and sugar solution, leaving the glass behind in the bucket. The solution is then heated to evaporate the water, leaving the sugar behind.   Use a magnifying glass and tweezers to safely remove the glass particles from the mixture.   Sweep a magnet across the spill to attract the glass particles and remove them from the mixture.

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.
