A chemical reaction is represented by a chemical equation that involves ions, atoms and molecular formulas. Use this resource to will learn about the main components of a chemical equation, and how to write and balance chemical equations. The main components of a chemical equation are: Reactants – the starting...
Do you feel confident about writing balanced equations for chemical reactions? Test yourself with a quiz. Your turn – chemical equations For questions 1—5, identify the reactants and products in the chemical equations. \(\ce{2H}_{2}+\ce{O}_{2}\rightarrow2\ce{H}_{2}\ce{O}\) \(\ce{CH}_{4}+2\ce{O}_{2}\rightarrow\ce{CO}_{2}+\ce{H}_{2}\ce{O}\) \(2\ce{Fe}_{2}\ce{O}_{3}+3\ce{C}\rightarrow4\ce{Fe}+3\ce{CO}_{2}\) \(\left(\ce{NH}_{4}\right)_{2}\ce{Cr}_{2}\ce{O}_{7}\rightarrow\ce{Cr}_{2}\ce{O}_{3}+4\ce{H}_{2}\ce{O}+\ce{N}_{2}\) \(\ce{CaCO}_{3}\rightarrow\ce{CaO}+\ce{CO}_{2}\) For questions 6—10, write balanced equations for the chemical reactions.
