Which of the following statements is true? metals usually gain electrons to fill their outermost shells. mixtures can be broken apart by physical processes. gelatin powder is dissolved in hot water. gelatin is the solvent. compounds with ionic bonds are difficult to dissolve in water.

Mixtures can be broken apart by physical processes.

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).
