Identify whether each of these hydrocarbons is saturated or unsaturated. Place an "S" for "saturated" next to each hydrocarbon letter that is saturated. Place a "U" for "unsaturated" next to each hydrocarbon letter that is unsaturated.

A. 2 central carbons, with C H 3 at each end, and also single bonded to the first carbon. B. 3 central carbons, with the first 2 double bonded to each other. The left end is bonded to C H 3, and the right end is bonded to 3 C H 3.C. 2 central carbons, with H above, below, and to both sides. D. 5 central carbons, with H above and below each, and H and to both ends of the chain.
ANWSERS:
A. ⇒ S

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
