Careful, precise and complete reasoning is needed for all items. For this assignment the term "independent particles" will mean particles of any of the substances involved. In other words, for substances that are elements it will mean atoms and for substances that are compounds it will mean molecules. 1) A clear liquid is mixed with a green liquid and a red liquid results. If the two initial liquids were elements, is the red liquid an element or a compound? How do you know? 2) For the situation in #1, would the number of independent particles change during the process? If yes, why and how? If no, why not? 3) A student mixes a blue liquid, that is an element, with a yellow liquid, that is also an element, and vigorous bubbling results and the final volume of liquid is noticeably less than at the start. What independent particles would we infer are in the bubbles and why? 4) Suppose a sample of substance A with 100 independent particles is mixed in a closed container with a sample of substance D that has 75 independent particles and we end up with a total of 50 independent particles. Can we infer whether this was a chemical or physical process? If yes, what kind was it and how do we know? If no, why can't we
