The type of energy transferred by a wave in a medium is kinetic energy.
OleMash [197]

Answer:

The statement is true.

Explanation:

The different means by which the energy is transferred is commonly termed to be 'wave'.

Wave refers to the disturbance transmission from a specific point to another. Different sources are involved in this transmission. The vibration of particles helps in the flow of energy from one medium to another. Vibration leads to the formation of kinetic energy flowing from one medium to another.

What is hydroxide ion concentration, [OH-], in a 1.37 x 10^-5 M solution of barium hydroxide (Ba(OH)2)?
Olegator [25]
Ba(OH)₂ is a strong base, therefore completely ionises in the solution as follows
Ba(OH)₂ --> Ba²⁺ + 2OH⁻
1 mol of Ba(OH)₂ gives out 2 mol of OH⁻
therefore number of OH⁻ moles are twice the amount of Ba(OH)₂ moles in the solution
hence,
[OH⁻] = 2[Ba(OH)₂]
therefore hydroxide ion concentration = 2 x 1.37 x 10⁻⁵ M
[OH⁻] = 2.74 x 10⁻⁵ M
coefficient = 2.74
exponent = -5
