Answer:
C.Tritium
Explanation:
Isotopes are forms of an element with different mass number but same atomic number. Mass number is the sum of the number of protons and neutrons in the nucleus of an atom, while atomic number is the number of protons.
Mass number = protons +neutrons.
Atomic number = protons only
We can say that mass number = atomic number + number of neutrons.
The number of neutrons is what differentiates the isotopes of an element.
For hydrogen element, it has three isotopes namely; protium, deuterium and tritium which have 0,1 and 2 neutrons respectively. Thus the answer is C

Answer:
Liquid water and ethanol are described as miscible because they <u>mutually dissolve each other in all proportions</u>.
Explanation:
Miscibility is defined as the property of two substances to mix each other in all proportions and make a homogenous mixture. This physical property is a reversible property and mainly depends upon the intermolecular interactions between the two substances.
Water: Water has a chemical formula H₂O, in which hydrogen atom is directly bonded to oxygen atom. Oxygen atom being more electronegative atom make the hydrogen partial negative and the oxygen itself becomes partial negative.
Ethanol: Ethanol has a chemical formula C₂H₅OH. In this molecule there is also the presence of O-H bond as that found in water and with the same partial negative charges.
Thus, the opposite partial charges of these molecules interact with each other and forms one of the strongest intermolecular bonds called as Hydrogen Bonds resulting in dissolution of each other in all proportions.
