B) the mass of the reactant equals the mass of the product.
Answer:
With more particles there will be more collisions and so a greater pressure. The number of particles is proportional to pressure, if the volume of the container and the temperature remain constant. ... This happens when the temperature is increased.
Explanation:
Sure. The kinetic energy at the bottom comes from the potential energy
that it had at the top, and the potential energy depends on the height where
it starts from. So the apple that falls from the highest height has the most
potential energy when it starts falling, and the most kinetic energy when
it's done falling.

If you fall off of the table, you land with more kinetic energy than if you
fall off of a book on the floor.
B; the law of inertia, there would be no friction to slow or stop the moving object
