1 The Language of Chemistry

2 Language of Chemistry  Formula: A combination of symbols that shows the ratio of elements in a compound. ex: H 2 O

3  Chemical Equation: A short, easy way to show a chemical reaction, using symbols instead of words ex: 2Na + Cl 2  2NaCl

4  Subscript:A small number in a formula that tells the number of each element in a compound. ex: CO 2

5  Coefficient: A BIG number placed in front of a formula in an equation that tells how many atoms of each reactant and product are involved in a reaction. ex: 2Na + Cl 2  2NaCl

6  Reactant:A substance that enters into a chemical reaction (what you start with).

7  Product:A substance formed as a result of a chemical reaction (what you produce or end with).

8 +:Is added to or combined with.  :Yields or produces.

9  (g): in gaseous state  (l): in liquid state  (s): in solid state  (aq): substance is dissolved in water  means heat is added
