<span>Hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. Thehydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton. The isolated hydrogen ion, represented by the symbol H +, is therefore customarily used to represent aproton.</span><span>

Answer:
D.) the density changed
Explanation:
This would be the answer because it is a specific amount of Nitrogen undergoing a physical change. Since the color and boiling point don't influence a change in volume, those are ruled out. Also, nitrogen's molecular mass never changes, so that would not make sense either. But if the density, which is mass/volume, has changed (more specifically decreases) then it means the volume has increased.
Hope this helps.
Answer:
The drawings are in the figure attached below.
Explanation:
"Constitutional isomers" is a term used in chemistry to refer to chemical compounds that have the same constitution and molecular formula distributed in a different structure. That is, the compound has the same atoms, but when built in a three-dimensional image, these atoms occupy different places within the same structure.
Force of the collisions increases due to increase in temperature.
Explanation:
Increase in temperature affects the average speed and kinetic energy of the particles.
The average speed of the gas particles gets increased , Kinetic energy of the gas particles also gets increased.
If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure.
Therefore, force of the collisions increases due to increase in temperature.
The high pressure and the low temperatures are the two conditions, which can restrict the effectiveness of the kinetic-molecular theory in illustrating the behavior of the gas.
At high pressures or at low temperatures, the real gases deviate substantially from the ideal gas behavior. Due to this, the two conventions of the kinetic molecular theory, where gas particles hold an insignificant fraction of the entire volume of the gas, and the force of attraction among the molecules of gas is zero would become uncertain.
