We'll learn about the five major types of chemical reactions: synthesis, decomposition, synthesis, single replacement (also called single displacement) and double replacement (also called double displacement). We'll look at examples of each, so that you can classify them, figuring out what type they are. In a synthesis reaction, a compound is made from more simple materials. In a decomposition reaction, a compound breaks down into simpler elements or compounds. In a combustion reaction, a compound (usually with carbon, hydrogen, and sometimes oxygen) combines with oxygen to give carbon dioxide and water. In a single replacement (displacement) reaction, one element that is on its own displaces another element in aqueous solution, kicking it out. In a double replacement (displacement) reaction, the positive and negative ions in two ionic compounds switch places, causing a precipitate to form.

Here are many example equations, so you can get lots of practice classifying them into the major types of chemical equations. In the video, we'll look at examples of synthesis, decomposition, combustion, single replacement and double replacement. The last two reactions are sometimes referred to as single displacement and double displacement.

Equation balancing will make sense! Here, we will do a bunch of practice problems for balancing chemical equations. We'll see the process or trial and error and the steps that you have to go through to balance chemical equations. You start by keeping track of the number of atoms on both sides of the equation, and then you add coefficients to one or more of the elements and compounds to make the number of atoms equal.

How to balance chemical equations. We'll start out with examples that show the concepts behind balancing chemical equations. We will start with a word equation, and then write a chemical equations, and then visualize the atoms and molecules and how they change. To figure out if the equations is balanced, we look at the number and type of atoms on each side of the arrow. If the number and type of atom is not the same on both sides, the equation in unbalanced. We need to change the number of one or more of the compounds in order to get the atoms to balance. We do this by placing coefficients (numbers) in front of each of the compounds. When balancing equations, you cannot ever change the subscripts of a compound.
