Final answer:
Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion, with the same velocity and in the same direction, unless acted upon by an external force. Newton's Third Law states that for every action, there is an equal and opposite reaction. An example of chemistry in action is the combustion of fuel in a rocket engine.
Step-by-step explanation:
Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion, with the same velocity and in the same direction, unless acted upon by an external force. For example, a book on a table will stay in place until it is moved by someone.
Newton's Third Law states that for every action, there is an equal and opposite reaction. Two examples of this law are the thrust produced by a rocket and the force exerted by the ground on a person when they jump.
An example of chemistry in action is the combustion of fuel in a rocket engine. The burning of fuels such as liquid oxygen and liquid hydrogen produces high-pressure gases that are expelled from the rocket, creating thrust.
