What is the net ionic equations of Cu (s) + 2 AgC2H3O2 (aq) --> Cu(C2H3O2)2(aq) + 2 Ag(s) ?

Which statement describes the appearance of a temperature-vs.-time graph? a horizontal line shows that the temperature increases at a constant rate over time. a vertical line shows that the temperature decreases at a constant rate over time. horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases. horizontal lines where the temperature increases are connected by upward-sloping lines where the temperature is constant for each phase.

In the particles are arranged in a regular, repeating pattern. a)a crystalline liquid b)a crystalline solid c)all gases d)all solids

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