Driving Forces

This lesson was what I believe will be the first of many confusing ones. Our teacher, Mrs. Frankenberg began to teach us what driving forces are, and at least one of these must be present for two separate components to react. The various driving forces are the formation of a solid, liquid, gas, or the transfer of electrons. Driving Forces Video For Help
This lesson was focused on the formation of a solid product from aqueous reactants. This reaction is what is called a double replacement reaction where two different compounds react to create two different compounds, by switching the positive ions, or cations switching in the products. For this to occur, the products must be aqueous and ionic, and one of the products must be a solid, and in order to know which compounds are solid, we have to memorize the solubility rules.
Here are those rules:

This is the standard for this type of reaction:

    Holly, I agree that this lesson was confusing! However, I believe that you described double reactions clearly. I like how you included the requirements of reactants and products for the formation of a solid. In addition, the way you related solubility rules to your explanation was very helpful. Lastly, I found your video very educational and it taught me a couple more things about the subject.

    Holly you did an awesome job of describing double reactions. Also your picture for solubility rules was very helpful.
