Predict and write formulas for the possible products, and determine whether a precipitate will form or not.

1) Predict and write formulas for the possible products, and determine whether a precipitate will
form or not.
B) If a precipitate forms, write the balanced total and net ionic equations for the formation of the
precipitate.
C) If no precipitate forms, write “NO REACTION” after the arrow.

2) Four metals (A, B, C, and D) were studied for activity, and the following information was
collected on the reactions between the metals and their salts:

3) A mineral of calcium with the formula CaCO3 Ca(OH)2 was analyzed by heating in a crucible, calculate mass and percentage.

4) Write balanced equations for the 2-step decomposition

5) Calculate mass, volume, number of moles (etc.)

6) a)Calculate for volume b) calculate for density

* When calculating, please use cross multiplication method with units canceling out.
*Make sure all numbers or chemical elements have units next to them, whether its (aq),(s),(g),(l) or grams, moles, g/mol, examples (Pb(NO3)2 (aq) + KI (aq), 33.82 g) .
