In chemistry, the pH of a substance is a measure of its acidity. The relationship between C, the hydrogen ion concentration in moles per liter, and p, the pH, is described by the equation below. C=10−p
A chemistry student has determined that the hydrogen ion concentration of vinegar is 0.00631 moles per liter. Which is closest to the pH of vinegar?

answer: i would say b.

explanation:

answer: mercury

explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
