**Balancing** **chemical** **equations** is about making sure that the same number of atoms of an element are on both sides of the **equation**. The focus will be adding, Why is that necessary? The law of conservation of matter says that matter can't be created or destroyed. It only changes forms. The** parentheses** mean there are 2 or more of what are contained in the** parenthses** in the compound. Since** balancing** means getting the same total numbers of each type of atom on each side, you must calculate the total number of atoms in the formula. Example: Al (NO3)3 contains 1 Al, and 3x1 =3 Ns and 3x3= 9 Os.. state of matter is shown in **parentheses** around each substance. • s= solid • l = liquid • g = gas • aq = aqueous (dissolved in H 2O) Because of the principle of the conservation of matter an **equation** must be balanced. It must have the same number of atoms of the same kind on both sides.**Chemical** **Equations** Lavoisier, 1788. Make sure students first understand the concepts of equality and order of operations. Here is a potential method of rearrangement that you could use. Step 1: write the **equation**. Step 2: carry out inverse operation (s). One per step. Students may ask why the m on the right-hand side disappeared. The reason is that you need to put a bracket around the complex ion to show how many of those whole complex ions there are in the compound. Examples: Mg (OH)2 Al2(SO4)3 (NH4)2SO4. That's it for brackets! Except that if you're not sure how to decide whether there's only one ion in a compound, or two or three, then have a look here: Top.

Answer (1 of 7): What are the **rules for balancing chemical equations**? I’m not certain what you mean by “**rules” for balancing chemical equations**. But I’m going to guess you mean “moves you are allowed to make”, just like the **rules** of chess or tic-tac-toe..

We follow exactly the same **rules** **for** counting atoms in these kinds of formulae, we just need to add up all instances of a given atom. **Parentheses** Very often in **chemical** formulae, we use **parentheses** to form subgroups of atoms within a molecule. Usually this has some meaning about the structure of the molecule, but don't worry about that for now.
