Isotones are nuclides that have the same neutron number but a different proton number. Therefore the answer is C. boron and carbon.
#1 The Correct Answer is D
<span>D) The Distance Traveled by The Wave During One Full Cycle.
Ex. frequency, wavelength, amplitude and wave speed. Amplitude is measured in metres (m). The greater the amplitude of a wave then the more energy it is carrying. The wavelength, λ, of a wave is the distance from any point on one wave to the same point on the next wave along.
(The symbol is a Greek letter, 'lambda'.)
#2 The Correct Answer is B
</span><span>B) Police Siren
Ex.Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist. </span>
Answer: No
Explanation: It's not balanced because four oxygen atoms in H2SO4, whereas there are 5 oxygen atoms in the reactants side. Also, there's more hydrogen atoms on the reactants side.
