The energy needed to change liquid to water vapor is the latent heat of __________.

The chemical formula for water is _______.

When water changes state, ______ is either lost or gained.

Match the change of state to the correct amount of heat added or removed, knowing the transition begins with 1 gram of the starting substance indicated.Water vapor to water

The total kinetic energy of the atoms and molecules in a substance is a measure of ______.

A ______ is the amount of heat needed to raise the temperature of 1 g of water by 1°C.

True or false: A water molecule is polar because the opposite ends have opposite charges.

When naming ionic compounds with transitions metals (roman numerals)

Gases consist of tiny particles (atoms/molecules)Particles are so small, relative to the distances between them, that the volume of the individual particles is assumed to be negligible (zero)Particles are in constant, random motion, colliding with the walls of the container. These collisions cause the pressure exerted by the gasParticles are assumed not to attract or to repel each otherAvg kinetic energy of gas particles is directly proportional to the Kelvin temperature of the gas

concentration of H and OH added is equilibrium constant

in its chemical structure (bond is more polar), and if it produces a weak conjugate base

reacting with any added H+ or OH- so that these ions do not accumulate (ion concentration does not increase)

Neutral water always has a pH of

measures the [ H3O ] + in a solution .
