GCSE Chemistry - Balancing Chemical Equations #4

The video tutorial explains chemical equations, focusing on the difference between word and symbol equations. It emphasizes the importance of balancing chemical equations by ensuring the same number of each type of atom on both sides of the equation. The tutorial provides step-by-step guidance on balancing equations, using examples like methane combustion and the reaction between sulphuric acid and sodium hydroxide. Key rules include not changing subscripts and using whole numbers. The process often involves trial and error to achieve a balanced equation.
