Why NH3 is easily liquefied than HCL?
Answer:Ammonia is more liquified than HCL because ammonia has higher critical temperature. Explanation: The liquification of a gas depends on the critical temperature. Higher the critical temperature,more easily the gas can be liquified.
Why SO2 is easily liquefied?
SO2 is heavier than water, and I expect only fails to be liquid at atmospheric pressures and temperature due to the lack of hydrogen bonding. As such, it takes very little pressure to liquefy it.
Which of the gases can be liquefied easily?
The permanent gases have weak intermolecular forces of interaction which makes the process of liquefaction impossible to carry out. Since the options have hydrogen, oxygen and nitrogen, it is clear that they are permanent gases. Only chlorine can be liquified easily by applying the suitable pressure on it.
Why can NH3 be liquified at a lower pressure than CO2?
NH3 has a smaller structure than CO2 so it will take more energy to break the inter molecular forces, It exists in liquid form at -2*c.
What do you understand by critical temperature?
The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.
What is the critical temperature of SO2?
SULFUR DIOXIDE
| Molecular weight: 64.06 | Critical temperature:430.8 K |
|---|---|
| Melting point: 198.7 K | Critical pressure:7.884 MPa |
| Boiling point:263.0 K | Critical density:525 kg/m3 |
| Normal vapor density:2.86 kg/m3 | (@0°C, 101.3 kPa) |
The critical temperature signifies the force of attraction between the molecules. The higher the critical temperature, higher is the intermolecular force of attraction and easier is the liquefaction of the gas. Gases require cooling and compression both for liquefaction.
Why a gas can be liquefied easily?
The molecules of any gas are relatively are far apart from each other while molecules of liquid are are relatively close together . Gas molecules can move from one place to other wherever space is available to them .
Which noble gas can be easily liquefied?
Xenon (Xe). As it is the largest among the given elements, it has the highest van der Waals attractive force.
Which gas is most easily liquefied CO2 or NH3?
NH3 gas is more easily liquefiable than CO2 gas.
Why CO2 and NH3 can be liquefied easily whereas H2 O2 and N2 Cannot be liquefied?
Selina – Chemistry – Class 7 So, since H2, O2 and N2 have very low or weak force of attraction among their molecules, therefore these gases cannot be liquefied. And as the molecular force of attraction is high in CO2 and NH3, so they can be liquefied easily.
How do gases compare to critical temperatures?
Microscopic view of a gas. Microscopic view of a liquid. The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied. Every substance has a critical temperature….
| substance | critical temperature (oC) |
|---|---|
| CO2 | 31.2 |
| H2O | 374 |
Why does NH3 exist in liquid form but CO2 does not?
NH3 has a smaller structure than CO2 so it will take more energy to break the inter molecular forces, It exists in liquid form at -2*c. CO2 has no special bonding, NH3 has a hybridization of sp3 while CO2 has hybridization of sp2 . Sp2 is more electronegetive so will easily break comparitively, Co2 exists in liquid form at -31*c to 20*c (may vary).
Is nhnh3 polar or nonpolar?
NH3 is a polar molecule because, in the NH3 molecule, it has three dipoles because of three bonds and these dipoles do not cancel out each other. They form a net dipole moment.
Why is the polarity of SO2 different in SO2?
Similarly, in the SO2 case, the lone pair present on Sulfur and Oxygen atoms produces repulsion between them. In such cases as SO2, where more than one lone pair group is present, the geometrical shape of the molecule is slightly different as compared to the molecule where all groups are bonds. Factors affecting the polarity of a chemical compound
Why does NaCl have a higher electronegativity than sulfur?
The electronegativity of Sulfur is 2.58 whereas the electronegativity of Oxygen is 3.44. And in the case of NaCl, the Chlorine atom has a higher electronegativity than Sodium, due to which the Chlorine atom pulls the electron shared pair towards itself.
