Chemistry Final Exam Review with Questions and Answers – 100% Solved
Ammonia, acid or base? - ✔✔✔-Base (drain cleaners are bases).
Are noble gases reactive? - ✔✔✔-NO! They have a full octet of electrons. They do not want to
react with anything.
Balance the equation:
C3H8 + O2 ---> CO2 + H2O - ✔✔✔-1 C3H8 + 3 O2 ---> 5 CO2 + 4 H2O
Balance the equation:
H2 + O2 -----> H20 - ✔✔✔-2 H2 + O2 ----> 2 H20
C2H4 + 3 O2 ----> 2 CO2 + 2 H2O
If you start with 45 grams of ethylene (C2H4), how many grams of carbon dioxide will be
produced? - ✔✔✔-141.4 g CO2
Define activation energy. - ✔✔✔-The energy required to start a chemical reaction.
Define equilibrium. - ✔✔✔-Equilibrium is established when the rate of the forward reaction is
equal to the rate of the reverse reaction.
Define neutralization. - ✔✔✔-When an acid reacts with a base to form water and a salt. pH = 7.
Define Reaction Rate - ✔✔✔-The decrease in concentration of reactants or the increase in
concentration of products with time.
