Matter is everything that surrounds us. It has mass and occupies a place in space. Matter can be described by measuring the value of its properties; for example: density, color, mass, volume, etc.
al ser homogenea no se puede percibir con la vista pero si se le agrega acido sulfurico la reaccion hara que el hidrogeno y el oxigeno se evaporen dejando unicamente una masa negra de carbono
No, ya que, es una mezcla homogénea, es decir, sus elementos están muy unidos mas no combinados de manera química, es posible separarlos pero con mucha dificultad, por tanto, es imposible diferenciarlos a simple vista. Se sabe que están distribuidos de manera uniforme, su estado es conocido como solución o disolución, tal como es el caso del azúcar.

Answer:
Explanation:
Basically, Kinetic Molecular Theory says that gas particles are in constant motion and that they show perfectly elastic collisions.
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision.
So the kinetic molecular theory says that gas particles stay moving constantly and don't lose energy when they run into each other.
Hope this helps!
