Explanation:

Hydrogen bond is a type of intermolecular chemical bond formed between two molecules. It is classified as a special dipole-dipole attraction between polar molecules in which a hydrogen atoms is directly joined to a highly electronegative atom.

  • A hydrogen nucleus has a high concentration of positive charges.
  • A hydrogen bond is actually an electrostatic attraction between the hydrogen atom (nucleus of one molecule and the electronegative atom, O or N or F) of a neighboring molecule.
  • The strength of the bond depends on the relative electronegativity of the atom directly joined to the hydrogen.
  • Hydrogen bonding forces is reflected in the physical properties of compounds such as water and ammonia.

Which cup has more thermal energy?
dybincka [34]

<em>Question: </em><em>Which cup has more thermal energy?</em>

<em>                   A. 2 liter cup of milk</em>

<em>                   B. 1 liter cup of milk</em>

<em>Answer: A. 2 liter cup of milk</em>

<em />

<em>Explanation:</em>

We have milk in both of the containers. The milk in both containers is the same temperature, so we will have to measure the amount of molecules. The amount of molecules makes it warmer, and if it is warmer, that is more energy. 2 liters have more thermal energy than 1 liter, because it has more molecules.

Our answer is 2 liter cup of milk.

Nitrogen has a density of 1.17 x 10^-3 g/cm^3. If you have 2,500 cm^3 of nitrogen gas, which of the following is the correct mas
ELEN [110]
I think the correct answer from the choices listed above is option D. The correct mass of nitrogen would be 2.9 g. The mass is calculated by multiplying the density and the volume of the substance. The correct answer should have two significant figures since it is the least precise operation.

Nh4i(aq)+koh(aq)→ express your answer as a chemical equation. identify all of the phases in your answer.
tester [92]
NH4I (aq)  +  KOH  (aq)  in   chemical   equation  gives

   NH4I (aq)  +  KOH (aq)   =  KI  (aq)  +  H2O(l)  +  NH3  (l)

Ki  is  in  aqueous  state  H2o   is  in   liquid  state  while  NH3  is  in  liquid  state

from  the  equation  above  1 mole of  NH4I (aq) react  with  1 mole of KOH(aq) to  form  1mole of KI(aq) ,  1mole of H2O(l)  and 1  Mole  of NH3(l)
