2h2 + o2à2h2o
how many water molecules are created when 32 grams of oxygen react completely with 4 grams of hydrogen?
a. 2
b. 20
c. 6.02 × 1023
d. 1.2 × 1024

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).

lol for the pointsss
