CONVERSION FACTOR PROBLEMS
Conversion factors can be used to convert units or to convert between equivalent ways of expressing a quantity. The quantity in the problem is multiplied by one or more ?conversion factors,? in which the numerator is equal to the denominator. Since the numerator and denominator of the conversion factor are equal, multiplying by the conversion factor is like multiplying by 1 and thus does not change the value of the original quantity. Use the table of English to Metric equivalents as needed. All answers should be in significant figures!
ANTIBIOTIC OVERDOSE CASE-STUDY QUESTIONS
The unit for the baby?s temperature is not given in the article. Which unit do you think it is?
Pneumonia is characterized by fever (a body temperature above 37.2 degrees C. Does the patient have a body temperature that indicates that he has pneumonia? Justify your answer with suitable calculations.
What was the baby?s weight in kg?
Hydrocarbons
Organic structures that contain only carbon and hydrogen
Saturated ? a compound is termed ?saturated? if it has the
maximum hybridization (sp3) at each carbon
Therefore: no double or triple bonds
A saturated carbon species is termed an ALKANE
The compound has a root name indicating the number of carbons and the ?ane suffix
CH3-CH3
ethane
An ALKENE has a carbon-carbon double bond
All three structures represent ethylene (or ethene)
An ALKYNE has a carbon-carbon triple bond

The Converse Classwork/Homework Name:
Is there enough information to prove that lines p and q are parallel? Explain your reasoning and if so, state the postulate or theorem you would use.
Choose the work that best completes the statement.
4. If two lines are cut by a transversal so the alternate interior angles are (congruent, supplementary, complementary), then the lines are parallel.
5. If two lines are cut by a transversal so the consecutive interior angles are (congruent, supplementary, complementary), then the lines are parallel.
