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.

I don't know if this is what you are looking for but maybe making paints out of things you find outside??? sry if this isn't what you were looking for
Those waves carry an amount of energy that can be measured. The energy in a wave is determined by two variables. One is amplitude, which is the distance from the rest position of a wave to the top or bottom. Large amplitude waves contain more energy. Wave A has a greater intensity and transfers more energy. Wave B has a greater intensity and transfers more energy. Waves that require matter to transfer energy are mechanical waves. The matter through which a mechanical wave travels is called a medium. A mechanical wave travels as energy is transferred from particle to particle in the medium. There are two kinds of mechanical waves. The greater the waves amplitude the greater the waves energy. ... A wavelength will travel only as long as it has energy to carry. Gamma rays
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. Electromagnetic waves cause oscillations in electrical and magnetic fields. It is important to remember that all waves transfer energy but they do not transfer matter . For example, if a ball is placed on the surface of a pond when ripples move across it, the ball will move up and down but not outwards with the wave.
Answer:
9028.8 J
Explanation:
The equation for working out the amount of thermal energy required is q = m c Δ T , where q is the amount of energy, m is the mass being heated up in grams, c is the specific heat capacity of what you're heating up in joules per gram per kelvin, and Δ T is the change in temperature in Kelvin.(Change in temperature will always give the same value,no matter Celsius or Kelvin)
mass = 27g, assuming specific heat capacity of water is 4.18 J/g*K, and the change in temperature is 90-10(=80) , the energy needed to raise : 80 × 27 × 4.18 = 9028.8 J
Answer:
The English and French versions of the list of ingredients must begin on a separate line, except, for small packages with an available display surface (ADS) of less than 100 cm 2, where the second language version of the list of ingredients may start after the end of the first language list [B.01.008.2(9), FDR].
