Which list shows the phases of matter in order from the greatest average kinetic energy to the least average kinetic energy per particle? A substance has a pH of 8.0. How would it be classified?

Accordingly to the gas laws, which variables are inversely proportional to each other (pressure, volume, temperature)?

part 2

What is the name of this atom?
What is the atomic number?
What is the atomic mass?
What is the charge?

the answer would be a

the answer is c i believe

oxygen, selenium, tellurium, and polonium.

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

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
