Sodium (Na) and water (H₂O) undergo a chemical reaction
that produces sodium hydroxide (NaOH) and hydrogen gas
(H₂).
Which equation represents this chemical reaction?
A. H₂ + 2H₂O → 2Na+ 2NaOH
B. 2Na+ 2H₂O → 2NaOH + H₂

Answer 1

Step-by-step explanation:

the answer is b.

since the only way to have a reaction, it needs to be equal on both sides, and 2Na+ 2H₂O as the reactants is the same on the product side 2NaOH + H₂

reactants

H = 4

Na = 2

O = 1

products

Na = 2

H = 4

O = 1

hopefully this helps :)
