4. Classifying The following are balanced equations for chemical reactions. Classify each of the equations as synthesis, decomposition, or replacement. a. 2 Al + Fe2O3 - 2 Fe + Al2O3 b. 2 Ag + S - Ag2S C. CaCO3 > CaO + CO, d. 2 NO + 0,- 2 NO

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.

Which is the solubility product expression for caf2(s)?  [ca2+]/[f–]2  [ca2+][f2–]  [ca]+[f]2  [ca2+][f–]2

The graph indicates the running route for tobias. which best describes his run? from time 0 to 6, he went fast and then slowed down. from time 6 to 10, he was at his slowest. from time 12 to 14, he went very slow. from time 14 to 18, he went toward the starting point.
