Diamond is a form of elemental carbon. Diamonds are weighed by carats, where 1 carat = 200 mg. Consider a 2.5 carat round cut diamond (approximate as spherical) with a radius of 3.24 mm. a) What is the density (g/cm3) of the diamond? (Vol of sphere = (4/3)??^3) b) How many carbon atoms are contained within the diamond? c) What is the mass (in g) of one single carbon atom?
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.
