Since there is loss of kinetic energy
Answer: Number of Hydrogen Bond Acceptor atoms =
2 Number of Hydrogen Bond Donor atoms =
1Explanation: Hydrogen bond interactions are formed between those molecules which contains partial positive hydrogen atoms bonded covalently to most electronegative atoms like
Oxygen,
Nitrogen and
Fluorine.
When hydrogen is attached to Oxygen, Nitrogen or Fluorine its
electron density decreases and gets partial positive charge, this partial positive charged hydrogen atom then makes hydrogen bonding with the most electronegative element (partial negative) of neighbor molecule.
In
Acetic acid there are two oxygen atoms hence there are two most electronegative elements therefore, two Hydrogen Bond Acceptor atom and each oxygen atom can accept two hydrogen bonds.
Also, it contains only one Hydrogen atom attached to oxygen atom so it has one Hydrogen Bond Donor atom.
Answer: The element is represented as Aluminium-27
Explanation:
Atomic number is defined as the number of protons or number of electrons that are present in an electrically neutral atom.
Atomic number = Number of electrons = Number of protons = 13
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons = 13 + 14 = 27
Thus the element with atomic number of 13 is aluminium and its mass number is 27. Thus it is represented as Aluminium-27
