The nitrogen is formed according to the following equations.
2NaN3 → 2Na+ 3N,
10Na + 2KNO, → K2O + 5Na2O + N2

what does the table look like

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.

it's c (engineer's do their work with mechanical stuff not on any living being)
