The gas-phase reaction between nitrogen and oxygen was carried out in a device designed to maintain constant pressure. there are two cylinders of equal volume with a reaction arrow between them. the cylinder on the left has two molecules of o 2 and two molecules of n 2. the cylinder on the right has four molecules of n o. a constant pressure is applied to both cylinders write the balanced chemical equation for the reaction between nitrogen oxygen. include physical states.

probably not if net force is zero

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
