introduces chemical reactions. Chemical reactions occur all the time in our everyday lives. Pick two common chemical reactions found on this Examples of Chemical Reactions in Everyday Life article and research the chemical equations. Next, write the chemical reactions. What kind of chemical reaction is it? Is heat energy lost or gained during the reaction? If you have 100 grams of the first reactant, how much product can you make? Are the products a different phase than the reactants (solid, liquid, gas)? What shapes are the reactant molecules? You may also use your eText as a source.
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.
