35) (c) electron acceptor
An oxidizing agent is called an electron acceptor as it accepts electrons and get reduced.
36) (d) Neutralization reactions
Because an acid-base reaction involves the transfer of acid to base resulting in neutralization.
37) (c) Law of conservation of mass
Law of conservation of mass states that in a chemical reaction mass of products is equal to the mass of the reactants.
38) (a) Atoms of each element
Because balanced chemical equation has same number of atoms of each element on reactants and produts side.
39) (e) equal to the mass of reactants
According to the Law of conservation of mass, in a chemical reaction mass of products is equal to the mass of the reactants.
40) The answer is theoritical yield.
The value obtained when an equation is used to calculate the amount of product that will form during the reaction is called theoritical yield.
