objectives(s):
in your own words, what is the purpose of this lab?

hypothesis:
in this section, include the if/then statements you developed during your lab activity. these statements reflect your predicted outcomes for the experiment.

procedure:
the materials and procedures are listed in your virtual lab. you do not need to repeat them here. however, you should note if you experienced any errors or other factors that might affect your outcome. using your summary questions at the end of your virtual lab activity, clearly define the dependent and independent variables of the experiment.

data:
record the composition of each of your compounds below. be sure to include the number of atoms for each element. an example has been supplied for you.

compound name chemical formula sodium (na) atoms calcium (ca) atoms hydrogen (h) atoms oxygen (o) atoms carbon (c) atoms chlorine (cl) atoms
ex: sodium
hypochlorite naclo 1 0 0 1 0 1

conclusion:
your conclusion will include a summary of the lab results and an interpretation of the results. write in complete sentences.
1. using two to three sentences, summarize what you investigated and observed in this lab.
2. why do you believe knowing how elements and compounds react together is essential in everyday matters?
3. some elements are more "reactive" than other elements; why do you think this is?
4. choose one of the compounds from the table and explain how you know the numbers of atoms in your formula.
5. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
