Limestone contains calcium carbonate (CaCO3), which is reactive with hydrochloric acid (HCL). The graph shows that large chips of limestone take longer to react with a dilute solution of hydrochloric acid than the small limestone chips do. An investigation was performed with equal masses of different-sized chips. Which statement BEST explains the observation from the investigation?

Group of answer choices

Larger chips have more impurities.

Smaller chips have a larger surface area.

Larger chips have more calcium carbonate.

Smaller chips are less concentrated.

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.

"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."

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
