Solve the following equation algebraically: a. b. c. d.

In the last of my series on balancing chemical equations, we look at the algebraic method, which is useful for balancing the hardest equations. That being said, it is a mathematical approach that is only suitable for mathematically-minded A Level or IB students. If you learn it, it can be a very fast way to balance difficult equations that are hard to balance by inspection , but there is no formal requirement to learn this method , nor should you ever need to use it to balance a chemical equation on an A Level or IB Diploma exam. There are two algebraic methods, the normal algebraic method and a simplified version, which is the best way to crack the toughest equations. Next, applying the Conservation of Mass, which tell us that the total number of atoms of each element must be the same on both sides, write algebraic rules for each element. To explain the logic behind this using Cl as an example, we know that the number of chlorine atoms must be the same on both sides of the equation. On the reactant side, we would have a total of b chlorine atoms. On the product side, MnCl 2 contains two chlorine atoms, so if its coefficient is c , it must contain 2c chlorine atoms, whilst KCl contains d chlorine atoms and so on, adding up the total number of chlorine atoms on the RHS. There are too many unknowns here, but we can substitute the rules for K and Mn into the rule for Cl to get rid of c and d :. Note that when you use the algebraic method, you may end up performing different substitutions in order to eliminate the unknowns. This is perfectly fine, there is no right or wrong approach.

Identify the element s appearing only once on the LHS and RHS of the equation If the element s is already balanced, write the same letter coefficient in front of its compounds If the element s is not balanced, write the letter coefficient in front of the compound containing the greater number of its atoms, then balance the element on the other side of the equation using the same letter coefficient applying Conservation of Mass Place letter coefficients in front of the remaining compounds. Solve each equation by finding square roots.
