Answer = B = Neutrons and Mass Number
Isotopes are defined as those atoms which have same atomic number but different atomic masses.
Atomic mass is basically the number of protons and neutrons present in an atom.
Atomic number is the number of protons present in an atom.
So, in isotopes the number of protons are same but the number of neutrons vary due to which atomic masses also vary.
In given three isotopes, all have same number of protons but different number of neutrons.
i.e.
H-1 = 1 P + 0 N = 1 u (Proton)
H-2 = 1 P + 1 N = 2 u (Deuterium)
H-3 = 1 P + 2 N = 3 u (Tritium)
Hence, it is clear that the number after H shows a change in number of neutrons and mass number.
Answer:

Answer:
D.
Explanation:
The Oil spill effects on environments and habitats can be catastrophic: they can kill plants and animals, disturb salinity/pH levels, pollute air/water and more. Read more about the types of oil pollution.
Mass = moles x Mr
So in this case the moles =1
And the Mr equals =11
So you would do - 11x1= 11grams
Answer:
It is higher.
Explanation:
The amplitude of a wave that carries more energy is usually higher.
The energy carried by a wave is related to the amplitude in such a manner that it is proportional to the square amplitude.
Amplitude is the maximum vertical displacement of a wave moving along its path.
- Energy of wave and its amplitude are directly proportional to one another.
- If the energy of wave is doubled, the amplitude is quadrupled.
- So, the higher the energy of a wave, the more its amplitude.
