Iron used in building materials, and it comes in two isotopes 54 Fe and 56Fe. 54Fe has an atomic mass of 53.939615 amu and an abundance of 5.845%. The other isotope, 56Fe, has a abundance of 91.754%. The average atomic mass between these tow isotopes is 54.4753172 amu. Calculate the actual atomic mass of 56Fe.
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.
