A.
a disturbance that travels through a medium with a transfer of energy and matter
B.
a disturbance that travels through a medium without a transfer of energy and matter
C.
a disturbance that travels through a medium with a transfer of energy and without a transfer of matter
D.
a disturbance that travels through a medium with a transfer of matter and without a transfer of energy
E.
a disturbance that travels only in the absence of a material medium

C. a disturbance that travels through a medium with a transfer of energy and without a transfer of matter

Explanation:

First: A wave is a disturbance. The disturbance is a vibration, a pulse. If you think in particles, by vibrating one particle causes the a neighboor particle to vibrate too.

Second: A wave travels through a medium, like water, air, solid matter, which is the case of mechanical waves (for instance sound and water warves) and electromagnetic waves (light). Mechanical waves only travel trhough a medium, electromagnetic waves can travel through a medium or through empty space. That is how the sun light can travels trhough space and arrive to our planet.

Third: Waves transfer energy but not matter. Waves move around an equilibrium position but the matter is not translated.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
