The chemical name for bleach is sodium hypochlorite (naclo). it is created by a chemical reaction between sodium (na), chlorine (cl), and oxygen (o). which substances are the reactants?

na
cl
o
naclo

NaClO is the molecular result, not a reactant. The reactants are basically the ingredients to the reaction.

Answer

Both are correct.

Explanation
The both equations are the same.
When we say that y=x+10, we can make x the subject of the formula and get;
y=x+10
y-10=x
x=y-10.

If the substitution is done correctly, that is x+10 for y and y-10 for x in the other equation then, both would be correct.
