1 $$$ Review $$$ Chemical Rxns (Ch. 11) Mole (Ch. 10)

2 It is a list of metals in order of decreasing reactivity. What reaction is it used for? Activity series, single replacement

3 What does the symbol mean? heat

4 What does the symbol (aq) stand for? aqueous

5 Equation that indicates only the particles that take part in a reaction. net ionic equation

6 Equation that shows dissolved ionic compounds as free ions. complete ionic equation

7 What is the generic formula for a combustion reaction? Fuel + O 2 -- CO 2 + H 2 O (If you had to, could you just be given the reactants and predict the correct products)

8 What is the generic formula for a single replacement reaction? A + BC --- AC + B (If you had to, could you just be given the reactants and predict the correct products)

9 What does aqueous mean? Dissolved in water

10 What is the symbol for a reversible reaction?

11 What is the generic formula for a synthesis (combination) reaction. A + B -- AB (If you had to, could you just be given the reactants and predict the correct products)

12 What is the generic formula for a double replacement reaction? AB + CD --- AD + CB (If you had to, could you just be given the reactants and predict the correct products )
