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.
Plants combine carbon dioxide and water to make glucose and molecular oxygen. This can be represented by the following chemical equation: 6CO2 + 6H2O → C6H12O6 + 6O2
The potential energy per mole for the reactants (6CO2 + 6H2O) is -4076 kJ/mol. The kinetic energy per mole of the products (C6H12O6 + 6O2) is 1276 kJ/mol greater than the kinetic energy per mole of the reactants.
What is the potential energy per mole of the products (in kJ/mol)?
