How can you make an item that is made of magnetic material become a permanent magnet instead of a temporary magnet? * 1.You can put it in a very strong magnetic field. 2.You can heat it while it is being influenced by a magnetic field. 3. You can leave it in the magnetic field of an actual magnet for a long time. 4. You can do any of the above.

You can put it in a very strong magnetic field.

i believe it is 40–40–20%

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).
