The common pain relievers – aspirin (C9H8O4), acetaminophen (C8H9NO2), and naproxen sodium (C14H13O3Na) – are available in tablets containing 125 mg of the active ingredient. Express your answers to three significant figures. 125 mg aspirin = ? C9H8O4 molecules 125 mg acetaminophen = ? C8H9NO2 molecules 125 mg naproxen sodium = ? C14H13O3Na molecules
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.
