300
Which type of reaction uses the activity series to predict whether the reaction will occur and how do you use the activity series for prediction?
What is a single replacement reaction. Elements listed higher in the listing are stronger/more reactive then those listed below them in rank; therefore they will kick them out of any compound taking their place, causing a reaction to occur.
300
True or False: All acidic and basic solutions contain both hydrogen and hydroxide ions, but bases contain more Hydrogen ions.
If false, identify the incorrect word.
What is False: replace hydrogen ion with hydroxide ions.
400
In this type of compound or bond, the bond that results causes valence electrons to become delocalized forming a "sea of electrons"; these electrons move freely around the resulting cations.
