CHEM 120 Chamberlain EXAM 1 Questions with complete
solution 2025
1. Hypothesis a testable educated guess
2. Experiment how we test hypotheses
3. Variable Idea to be tested (only one)
4. Control Something the variable is tested
against
5. Experimental protocol How do you do the test?
6. Results Data generated comparing variable to
controls. Includes statistics to show
results are meaningful
7. Conclusion Interpretation of results
8. independent variable The experimental factor that is
manipu- lated; the variable whose
ettect is being studied.
9. dependent variable The variable that depends on the
inde- pendent variable
10. Protons Positively charged particles
11. Neutrons the particles of the nucleus that
have no charge
12. Electrons Negatively charged particles
