Two parts

This question has multiple parts. Work all the parts to get the most points. a In this diagram the different colored spheres represent atoms of different elements. Four changes, denoted by the four numbered arrows, are shownt. Select the change, by listing the arrow number, that represents each of the listed situations. (Note that there may be more than one correct answer for a given situation and that answers may be used more than once or not at ali.) For a chemical process iffolving diatomic compeunds, check all the changes that apply. (Select all that apply.) change 1 change 2 changes 3 change 4 b For a process that results in a pure substance, check all the changes that apply. (Select all that apply.) * change 1 change 2 change 3 change 4
