A thermometer is placed in water in order to measure the water's temperature. What would cause the liquid in the thermometer
to rise?
The molecules in the water move closer together.
The molecules in the thermometer's liquid spread apart.
The kinetic energy of the water molecules decreases.
The kinetic energy of the thermometer's liquid molecules decreases

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).

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
