In order to participate in a hydrogen bond, a hydrogen atom must be covalently bonded to one of three elements. What are they?
Lyrx [107]

Oxygen, Nitrogen and Fluorine

Explanation:

In order to participate in a hydrogen bond, a hydrogen atom must be covalently bonded to one of the oxygen, nitrogen and fluorine.

  • Hydrogen bonding is a type of dipole - dipole attraction between two specie.
  • It is an intermolecular force of attraction.
  • This bond type forms when hydrogen is bonded to a more electronegative atom.
  • These atoms are oxygen, nitrogen and fluorine
  • These species draws the electron shared more to themselves and leaves a partial positive charge on the hydrogen and a negative charge on them.
  • The electrostatic force of attraction between the hydrogen of one molecule and the O/N/F of another molecule cause the formation of hydrogen bonds.

Powdered aluminum is used in the thermite reaction for welding metals. what role does the powdered aluminum play in this reactio
BigorU [14]
Powdered aluminum serves the reducing agent for this reaction. Aluminum powder is known as a powerful reducing agent. <span>Iron(iii) ions would have greater electron affinity as compared to a metallic aluminum thus it would easily gain electrons from aluminum making it less positive in this case formed into a neutral atom. </span><span>The chemical reaction is </span>

<span>Fe2O3 + 2Al = Al2O3 + 2Fe. 
</span>
<span>Oxygen in the oxide compound does not participate in this redox reaction, as it is not changed </span>chemically<span>. Fe2O3 is an ionic compound which has of Fe[3+] ions and O[2-] ions. So, the net ionic reaction would be</span>

<span>Fe3+ + Al + 3O2- = Al3+ + Fe + 3O2- </span>

<span>The ionization energy of aluminum is greater than that of iron, so the said reaction would generate large amount of heat which is needed in welding.</span>

TRUE OR FALSE
Talja [164]

Answer:

True!

Explanation:

A spectrum is simply a chart or a graph that shows the intensity of light being emitted over a range of energies. Have you ever seen a spectrum before? Probably. Nature makes beautiful ones we call rainbows. Sunlight sent through raindrops is spread out to display its various colors (the different colors are just the way our eyes perceive radiation with slightly different energies).

Hope i helped!
