Q3 Write a balanced equation for each of the following reactions. Write the correct formulas of the reactants and products and the states of each. a. Liquid pentane (C3H12) and oxygen (O2) gas react to form carbon dioxide and water. b. Sodium and water react to form sodium hydroxide and hydrogen gas (H2). c. Iron and oxygen (02) gas react to form iron(III) oxide.
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.
