1. What do you observe when you poor a hot into the glass
containing intant coffee?

The water in glass turns dark brown.

This is due to diffusion where the coffee molecules move from the region of their high concentration to a region of their lower concentration in water.

The instant coffee acts as a solute when hot water (the solvent) is poured.  The instant coffee quickly dissolves and makes a solution.

Explanation:

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).

um i think it might be a car?
