The equivalence point in a titration refers to the point when A. the mł of the acid equals the mL of the base.

B. the molarity of the acid used in the reaction equals the molarity of the base used in the reaction.

C. the number of moles of one reactant reacts completely with the moles of the other reactant.

D. the acid in the flask turns clear.

C) the number of moles of one reactant reacts completely with the moles of the other reactant.

Explanation:

it's right put it

C

Explanation:

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

the product of the pressure and volume is also constant
