You start with 1 L of CO2 at standard temperature and pressure in a closed container. If you raise the temperature of the gas, t

pychu [463]

Answer:

Increase

Explanation:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

If the initial temperature and pressure is standard,

Pressure = 1 atm

Temperature = 273.15 K

then we increase the temperature to 400.0 K, The pressure will be,

1 atm / 273.15 K = P₂/400.0K

P₂ = 1 atm × 400.0 K / 273.15 K

P₂ = 400.0 atm. K /273.15 K

P₂ = 1.46 atm

Pressure is also increase from 1 atm to 1.46 atm.

Suppose a chloride ion and a sodium ion are separated by a center-center distance of 5Å5Å. Is the interaction energy (the energy

Allisa [31]

Explanation:

The water is a polar solvent which means it strongly interact with the ionic species dissolved in it. The reason is due to the formation of Hydrogen bonding. Hence, the ionic species are known to be stabilized by solvation.

The H- bonding is the interaction of H-atom of solvent molecules with the electronegative atom of same molecule or, solute species. Ionic solutes dissolve by forming H- bonding.

But in case n- pentane which is a non polar and lack of H-atom attached to electronegative atom. Hence, there is no H- bonding.

Thus, the energy required to separate Na+ and Cl- ion would be huge in water compared to n-pentane.
