Answer:
C. NaOH acts as a reactant in the reaction
Explanation:
Because during the saponification process, Na+ replaces the H+ in the fatty acid been used for the saponification process
The given reaction is,

In this reaction, the positive and negative ions of both the reactants rearrange resulting in the formation of new compounds. Such a reaction is referred to as the double replacement or the double displacement reaction. These type of reactions usually take place in aqueous medium and one of the products is a precipitate.
Double displacement reactions are of three types, precipitation reaction, neutralization reaction and reaction involving the formation of a gas. The given reaction is a precipitation reaction as one of the products is a solid.
Answer:
which formula can be used to calculate the molar mass of hydrogen peroxide (H2O2)?
» <u>d.2 x molar mass of H + 2 x molar mass of O</u>
Explanation:
Since we've two hydrogen atoms and two oxygen atoms, we multiply each mass by 2
