In this monomial , -- is the variable --- is the coefficients and the degree is--.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

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 75.0%.

i think its 100.

hope this !
