Answer:

A wave transfers energy through a medium or empty space without transporting matter.

Explanation:

A wave is a transmission of a disturbance from one point known as the source to another.
Waves may transfer energy through a material medium or a vacuum without transporting matter.
Waves that transfer energy from one point to another through a material medium are known as mechanical waves.
Electromagnetic waves, on the other hand, are those that do not require a material medium for transmission, the transfer of energy is through a vacuum.
Waves can also be either transverse or longitudinal waves based on the vibration of particles relative to the direction of wave motion.

Answer: The coefficient for the diatomic oxygen (O2) is 3.

Explanation:

To know the coefficient for the diatomic Oxygen, we need to balance the equation.

Fe + O2 -------> Fe2O3

LHS of the equation; Fe = 1 , O2 = 1

RHS of the equation; Fe = 2 , O = 3

∴ Multiply 'Fe' on the LHS of the equation by 4 and O2 by 3

Doing that will give the balance equation which is;

4 Fe + 3 O2 --------> 2 Fe2O3
