Initially the balloon was 21 liters with 4.00 moles of hydrogen
Therefore 1 mole of hydrogen had 21/4 = 5.25 liters
Therefore; 1 mole of oxygen would still contain 5.25 liters
Hence; 2 moles of oxygen contain 5.25 × 2 = 10.5 liters
Thus; the total volume of the balloon will be;
21 +10.5 = 31.5 liters
Answer:
a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
Explanation:
A hydrogen bond is a partial intermolecular bonding interaction between a lone pair on an electron rich donor atom, particularly the second-row elements nitrogen, oxygen, or fluorine, and the antibonding molecular orbital of a bond between hydrogen and a more electronegative atom or group.
<span>he ratio of the RMS velocities is 0.837
Now the RMS velocity is inversely proportional to the square root of the Mol Wt
So we have V1/V(N2) = sq rt (28/M1)
So [V1/V(N2)]^2 = 0.837^2 = 0.70 = 28/M1 from which M1 = 28/0.7 = 39.97 (Ar)</span>
Answer:
Hi
The high dipole moment of water and its ease in forming hydrogen bonds make it an excellent analysis. A molecule is soluble in water if it can interact with its molecules through hydrogen bonds or ion-dipole interactions.
With anions that have oxygen they can form hydrogen bonds, since oxygen acts as their acceptor. The attraction of the anion on the water dipole must be taken into account. The same goes for Cl-F, which have solitary electron pairs and can act as hydrogen bridge acceptors. On the other hand, cations such as Na+, K+, Ca++ or Mg++ are surrounded by water molecules to which they are joined by dipole ion interactions while oxygen atoms are oriented towards the catión.
