The odor of a smelly shower drain can be eliminated by removing debris from the drain. Discarding the odor-causing material in the garbage outside the home ensures the smell does not invade other areas. Boiling water dissolves oils and grease deposited on the sides of the pipe in the drain, which add to the smell.
Luckily for us, Nernst derived an equation that allows us to determine at what point the two forces (chemical and electrical gradients) balance each other - in other words, at what point we have an ionic equilibrium.
Unbalanced equations are known as skeletal equations and cannot be used in calculating chemical reactions. Creating a balanced equation rather than using a skeletal equation is very important, as the number of atoms in a chemical compound always remains the same. Atoms cannot be added to or disappear from an equation.
