Drawing a conclusion derived from knowledge of an established principle is called .

a. Inductive Reasoning
b. Abductive Reasoning
c. Subjective Reasoning
d. Deductive Reasoning

the answer is the first option

explanation:

just googled it m8. not that hard

lol

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

elements make up everything, and they combine to make compounds.

the answer is c

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.
