1. a criminal profiler is seeking to create a profile and notes that a suspect liked to watch the fire trucks arrive at the fires that he set. what is this an example of? antecedent body disposal post-offense behavior method and manner 2.the innocence project utilizes criminal profiling to investigate serial and homicide cases. true false

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

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.
