You will relate writing a chemical formula to writing musical notes.
After completing this tutorial, you will be able to complete the following:
Chemical formulas are a way for scientists to communicate which elements are participating in a reaction. Elements are represented on the periodic table by one or two letters. The first letter is always capitalized, and if a second letter is used, it is lower-case.
Compounds are composed of more than one atom of different elements. The symbols are placed together to demonstrate which elements are in the compound. If more than one atom of the same element is needed, a subscript is added after the element's symbol.
The final balanced equation will have the same number of each atom in the reactants and the products. If they do not initially match in number, then coefficients are used in front of the compounds to balance the chemical equation.
