The lowest value of the henry's law for methane gas (CH₄) will be obtained with H₂O as the solvent and a temperature of 349 K.
The lowest value of the henry's law for methane gas (CH₄) will be obtained with H₂O as the solvent and a temperature of 349 K.
Henry's law: This law states that at a constant temperature, the amount of a gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas that in equilibrium with that liquid.
Mathematically it can be written as:
So, for the methane gas , lowest value of the henry's law obtained at 349 K and with H₂O as the solvent.
It will float, because it is almost weighs like a pen.
Answer:
Explanation:
Electron affinity is the energy released in adding an electron to a neutral atom in the gas phase.
It is a measure of the readiness of an atom to gain an electron. This property is very peculiar to non-metals. The higher the value, the greater the tendency to accept electrons.
Across a period electron affinity increases due to the increasing nuclear charge not being compensated for.
Down a group, electron affinity decreases due to the low nuclear charge and the large atomic radii.
The exception to this rule is the stability of half-filled sublevels. For example, nitrogen has a configuration of 2,5 with sublevel notation of 1s²2s²2p³.
The p-sublevel has a degeneracy of three and the three electrons goes in singly. This makes the configuration stable.
We expect such an atom to have a higher electron affinity but its configuration is stable and carbon would have a higher affinity than it across the same period.
Half filled sublevels are exception to the trend of electron affinity.
Yes, because if you have a flower and it reproduces then there's a HIGH chance that the next flower will be the same color because of traits! <span />
