Conclusion
Answer the following questions in complete sentences, and justify your responses.
1. After how many time intervals (shakes) did one-half of your atoms (candies) decay?
2. What is the half-life of your substance?
3. If the half-life model decayed perfectly, how many atoms would be remaining (not decayed) after 12 seconds?
4. If you increased the initial number of atoms (candies) to 300, would the overall shape of the graph be altered? Explain
your answer
5. Go back to your data table and for each three-second interval, divide the number of candies decayed by the number
previously remaining and multiply by 100. Show your work

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
