A student was given a powder made from a mixture of barium chloride and magnesium chloride. The student dissolved the powder mixture in water in a conical flask and added an excess of sulfuric acid. A white precipitate formed and was filtered off, washed and dried. a) Identify the white precipitate. b) Write the complete ionic equation and the net ionic equation for the student work. (Hint: use the precipitation rules). c) Why, in your opinion, should the student filtered off the precipitate and dry it?

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.
