In chemistry: are there EVER double replacement reactions that do NOT occur (i.e. when you add diatomic molecule + diatomic molecule there is no reaction)? How can you tell just from looking at the chemical equation, chemical charges, and activity series? Please explain!
ThanksIn chemistry: are there double replacement reactions that do NOT occur? How do you know?Yes, there are double replacement reaction that do not occur. If both the products of the reactants are (aq) then the reaction never took place. To determine whether a reaction will occur, you must familiarize yourself with the Solubility Rules in your chemistry book.
Example: NaOH(aq) + KNO3(aq) ----%26gt; NaNO3(aq) + KOH(aq) there is no reaction, because the product are soluble in water.
As far as the chemical charges, I believe you should review the chapter on Molecules and Compounds in you chemical book.
Hope this helps,
