Don't just use this question for points- I used cotton balls in my vehicle design because they are fluffy and soft, therefore they could cushion the egg. However, after my test I realized that cotton balls allow for the egg to move around in the vehicle because they are not compact. This is an example of:

1. a trade-off

2. a constraint

3. the engineering design process

4. a failure

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.

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.
