- the rate of the reaction
- Sodium Chloride + Silver Nitrate --> silver chloride + sodium nitrate is an example of
- a word equation
- in a chemical equation, a small triangle found above the horizontal arrow tells us that
- heat is used
- when silver nitrate and sodium chloride solutions are mixed together
- a percipitate is formed
