An acorn falls from a tree. which of the following statements is true?
the force of gravity is acting on the acorn.
the force of gravity is the only force acting on the acorn.
a frictional drag force is acting on the acorn.
the net force on the acorn is less than the force of gravity.

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).
