You will study several different
types of chemical reactions and learn to represent them using words or formula of the substances involved.
The simplest is was of representing a reaction is using the names of
the chemical involved (called word equation).
A chemical equation is a chemical short-hand for a host of information
For example,
•Sodium + oxygen ¾® Sodium oxide
–Everything to the left of the arrow is referred to as
reactants and everything to the right product(s)
–“à”
means produces or yields or gives or results in
–“+” on the left side means “reacts with” or “combines
with”
–(If “+” appears on the right hand side it means “and.”)
