Astudent is trying to create a table that compares hypotheses, theories, and laws. which of the following questions would most likely fill the blank in the table? is it an intelligent guess? is it newly formulated? is it based on observations? has it been proved?

Is it based on observations?

Explanation:

A hypothesis is a statement that is based on observation. A hypothesis can be disproven but not proven to be true.

A theory is a system of thoughts of some phenomenon or thing that is based on observation

Law is the rules and regulations that guide a state or an organization that is established based on observation.

For a student to create a table to compare hypotheses, theories, and laws he or she has to know whether the comparison is based on observation.  

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).

i do not get it   at all
