Review for test on chapter 3 and conservation of matter

Chapter 4 will not be on the test because of the amount of material in chapter 3 and the time factor. It is only on chapter 3, but skills from 1 AND 2 MAY ALSO BE NECESSARY. study guide: contributors to the structure of the atom, what the experiment was, and how it shows their ideas about the atom. What conclusions can we draw from their work. What is correct and what is incorrect. Dalton's 5 statements Law of definite proportions ( 1 compound); Law of multiple proportions (when comparing 2 or more compounds); Cathode ray tubes giving off electrons that are negative; Rutherford's gold foil experiment and alpha (helium nucleus) particles are positive; Nuclear forces; Atomic number and protons; Mass number =p+ and N also is rounded off average atomic mass; isotopes vary in neutrons heavy or lighter that average; two ways to designate and isotope; ions gained electrons to become negative anions or lose to be positive cations; calculating average atomic masses of isotopes (see your worksheets); The mole; molar mass = # g per mole of substance Avogadro's number =6.02 x 10^23 particle = 1 mole Gram to mole conversions using dimensional analysis mole to gram " " Law of conservation of mass and the three things that must hold true about chemical reactions. Use your lab as an example.

test friday review thurs

You do not have to write a lab for the Law of conservation of matter, but can you apply what you learned about the law and apply it to this particular experiment to explain your results? I hope you can. Research what you can about the reaction of baking soda and acetic acid, it will help on the test.
