- in a double displacement or two compounds exchange bonds or ions in order to form different compounds.AB + CD = AD +CB
- a double displacement reaction occurs between sodium chloride and silver nitrate to form sodium nitrate and silver chloride.
NaCl(aq) + AgNO3(aq) = NaNO3(aq) + AgCl(s)
steps for balancing chemical equations
- Check for diatomic molecules.
- Balance the metals not .
- Balance the nonmetals.
- Balance oxygen.
- Balance hydrogen.
- The equation should now be balanced, but recount all atoms to be sure.
- Reduce coefficients.
