Question

During science lab, Jacob mixes together sodium hydroxide (NaOH) and hydrochloric acid (HCl). The two chemicals react to form sodium chloride (NaCl) and water (H2O).

Which of the following are reactants in the chemical reaction described above?
A.
sodium hydroxide and sodium chloride
B.
sodium hydroxide and hydrochloric acid
C.
sodium chloride and water
D.
hydrochloric acid and water

Answer 1

The answer is B. Because reactions are what goes in. Products are what comes out

Answer 2

the answer is B sodium hydroxide and hydrochloric acid

Step-by-step explanation:

The reactants in a solution are always the substances that are involve at the beginning of the chemical equation. with this paragraph about what Jacob did in the lab we can write a chemical equation

NaOH + HCl ⇒NaCl + H2O

the two first mixed substances were sodium hydroxide and hydrochloric acid hence they are the reactants, the substances that reacts to form a product that in this case the product is the two substance on the right of the arrow NaCl and H2O
