At a very high pressure, the volume of occupied by a real gas is greater than the volume predicted by the ideal gas law, because the volume of the actual particles is more significant under high pressure.
<h3>
Behavior of gases at low pressure and high pressures</h3>
At low pressure, the distance between gas molecules is relatively far apart, but as the pressure of the gas increases, the distances between theses gaseous molecules becomes smaller.
Due to the high pressure the volume occupied by the gas molecules becomes significant compared with the volume of the container.
As a result, the total volume occupied by the gas will be greater than the volume predicted by the ideal gas law.
Thus at a very high pressure, the volume of occupied by a real gas is greater than the volume predicted by the ideal gas law, because the volume of the actual particles is more significant under high pressure.

Answer: B.) I, II, and III
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and for the reaction comes out to be positive.
I) The temperature (of water) increases when calcium chloride dissolves in water : Thus the reaction is exothermic and for the reaction comes out to be negative.
II) Steam condenses to liquid water : The energy is released when bonds are formed when it coverts from gas to liquid and thus for the reaction comes out to be negative.
III) Water freezes : The energy is released when bonds are formed to get converted from liquid to solid and thus for the reaction comes out to be negative.
IV) Dry ice sublimes : The energy is absorbed when bonds are broken to get converted from solid to gas and thus for the reaction comes out to be positive.
Answer is: benzaldehyde will have <span>one or two bands of moderate intensity in the region 2695 - 2830 cm</span>⁻¹ because of <span>C-H stretch. </span>Presence of a moderate band near 2720 cm⁻¹ is helpful in determining whether or not a compound is an aldehyde. Aldehyde, always have peak around 2720 cm⁻¹.
Answer:
Masses of bromobenzene molecular ions will occur at 156 and 158 m/z.
Explanation:
The molecular ion peak is the signal in the mass spectrum of a compound that represents the molecular ion (denoted as M). Compounds that are composed of atoms having abundant isotope also shows M +1 and M+2 peaks (depending on the isotope).
In the given bromobenzene compound, an atom of bromine is present. The two isotopes with considerable relative abundance of Br are 79Br and 81Br with a difference of two units in their mass. This means that two molecular ion peaks with a difference of two units will appear in the mass spectrum. The mass of the whole compound is 156 amu. Hence, the molecular ion peaks will appear at 156 m/z and 158 m/z due to the two isotopes of bromine.
