Question
Chapter 3, Problem 1CR
Interpretation Introduction
Interpretation:
The definition of chemistry should be determined on the basis of the text of the chapter 1 and after completed few more chapters, whether the definition of chemistry is changed or not. Whether you have better appreciation for what chemists do or not should be explained.
Concept Introduction:
Chemistry is concerned with the study of matter. It involves study of chemical and physical properties of different substances and also to use different

Based on the quote below,
"We may lay it down as an incontestable axiom that, in all the operations of art and nature, nothing is created; an equal amount of matter exists both before and after the experiment. Upon this principle, the whole art of performing chemical experiments depends." --Antoine Lavoisier, 1789
Explain what the quote implies and relate it to the "Law of Conservation of Mass".
What is wrong with the expression “That is just a theory,” if by theory the speaker is referring to a scientific theory?
what is an atom? What is it characteristics? How does an atom live and exists in the biosphere?

- Paragraph Styles ntroduction: Models are very important for chemists. You cannot see detailed features of a molecule, e vith a microscope. However, you can build a molecule that shows some of the properties that chemists letermined through experimentation. In this investigation, you will use a molecular model kit to assemb nodels of a few molecules. Question: what can you predict about the structures of molecules by building models? Procedure: You will need a molecular model kit to use for your group 2. Complete the table on the back of this note for drawings in procedure steps 3, 4, and 5. 3. In your table, write the name and formula, and draw a Lewis structure of each molecule below. a. hydrogen bonded to hydrogen b. chlorine bonded to chlorine oxygen bonded to two hydrogen atoms carbon bonded to two oxygen atoms C. d. e. nitrogen bonded to three hydrogen atoms f. carbon bonded to four chlorine atoms g. nitrogen bonded to three fluorine atoms a.
