Question

How do you write the equation for this reaction: Potassium chloride and silver nitrate react to form potassium nitrate and silver chloride?

Answer 1

`"KCl + AgNO"_3` `rarr` `"KNO"_3+"AgCl"`

Explanation:

Formulas for the compounds:

`"KCl":` potassium chloride (reactant)
`"AgNO"_3":` silver nitrate (reactant)
`"KNO"_3":` potassium nitrate (product)
`"AgCl":` silver chloride (product)

`"KCl + AgNO"_3` `rarr` `"KNO"_3+"AgCl"`

If the compounds are in aqueous solution, then their physical states could be added.

`"KCl(aq) + AgNO"_3("aq")` `rarr` `"KNO"_3("aq")+"AgCl(s)"`
