Bohr: Electrons can jump from a path in one level to a path in another level.Electrons travel in certain paths, or energy levels
Answer: protons
Explanation:
The atomic # identifies the amount of protons in an atom
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:
D.the wavelength of a wave is the distance between two successive peaks or two successive troughs or a peak and trough
In a number with decimal, zeroes to the right of last non-zero digit are significant.
Hence there are 4 significant digits in 3.140.
Hope this helps, have a great day ahead!
