Erika made the table below to compare and contrast the properties of metals and nonmetals. Most Metals Most Nonmetals Good conductor Poor conductor High melting point Low melting point Not malleable Malleable Hard Not hard What mistake did Erika make in her table?

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).

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
