1) A common experiment to determine the relative reactivity of metallic elements is to place a pure sample of one metal into an aqueous solution of a compound of another metallic element. If the pure metal you are adding is more reactive than the metallic element in the compound, then the pure metal will replace the metallic element in the compound. For example, if you place a piece of pure zinc metal into a solution of copper(II) sulfate, the zinc will slowly dissolve to produce zinc(II) sulfate solution, and the copper(II) ion of the copper(II) sulfate will be converted to metallic copper. Write the unbalanced equation for this process. (Include states-of-matter under the given conditions in your answer.)

Periodic Trends in Group
II
Objective
In this experiment, the trend in one of the several periodic
properties for group II of the Periodic Table will be
determined.
Introduction
Elements in the same group of the Periodic Table have similar
chemical and physical properties that gradually change as one goes
from one element in the group to the next. By observing the trends
in properties, the elements can be arranged in the order in which
they appear in the Periodic...
