Why is solute particles must be attracted to solvent particles to enable formation of a solution?
Solute particles being attracted to solvent particles facilitates the process of dissolving by overcoming intermolecular forces between solute particles, and between solvent particles. This attraction helps the solute particles break apart and disperse evenly in the solvent, creating a homogeneous solution. If there is no attraction between solute and solvent particles, the solute would not dissolve effectively, leading to poor solubility and the formation of separate phases.
Does the formation of solid liquid solutions release or absorb heat?
It could do either.
What happens to the particles in a solid when it dissolved?
The particles in the solid (solute) break apart and form links with the particles in the liquid (solvent). There are strong forces of attraction between the molecules and particles inside the solute. These forces keep the particles together and make the solute a solid because they attract the solute particles tightly together. There are also strong forces of attraction between the molecules and particles inside the solvent. These forces keep the particles together and make the solvent a liquid because they attract the solvent particles slightly together. There is also an attractive force between the solute and solvent particles. To break these forces and from a bond between the solute and solvent particles energy is needed. This energy is gained from heat (the process of dissolving is speeded up through heat.) In conclusion, the particles in a solute break apart of their attractive forces and form bonds with the solvent particles through the attraction between the solute and solvent particles and through the energy gained by heat.
What is the name of the process that involves a strong attractive force that keeps atoms together?
Chemical Bonding
What is the process of precipitation at the molecular level?
Precipitation at the molecular level occurs when solute particles in a solution come together to form solid particles (precipitate) due to a change in solubility. This can happen when the solution becomes supersaturated, leading to the formation of solid particles and their settling out of the solution. The process involves attraction forces between solute molecules overcoming the forces keeping them in solution, resulting in their aggregation and precipitation.
What is the Difference between condensation and accretion?
Condensation is the process where a gas transforms into a liquid, while accretion is the process of particles coming together and sticking to form a larger object, like in the formation of planets. Condensation involves a change in state, while accretion involves the growth of an object through the accumulation of particles.
Ability to force a gas into smaller space is called what?
It is called compressibility. The compressibility of gases can be explained by the kinetic particle theory: due to the large amount of space between the gas particles and the weak attraction forces between them, gases can easily be compressed (the particles are brought closer to each other, thus reducing the volume of the gas).
Which process involves the engulfing of particles?
Phagocytosis is the process that involves the engulfing of particles by cells, particularly immune cells like macrophages and neutrophils. During phagocytosis, the cell membrane surrounds and engulfs the particles, forming a vesicle called a phagosome that allows the cell to digest and eliminate the material.
What is the difference between eluviation and leaching?
Eluviation is the process by which minerals or fine particles move down through the soil horizon due to the movement of water, while leaching is the process where water moving down through the soil carries away dissolved nutrients or minerals. Eluviation mainly involves physical movement of particles, while leaching involves the chemical removal of substances from the soil.
How do strength of attractions between particles and the motion of particles interact to cause the process we call sublimation?
Sublimation occurs when a substance transitions directly from a solid to a gas without passing through the liquid phase. This process is influenced by the strength of attractions between particles; in solids, these attractions are strong, keeping particles closely packed. When energy is added (e.g., through heat), it increases the motion of the particles, allowing them to overcome these attractions and escape into the gas phase. Thus, the interplay between particle motion and attraction strength facilitates sublimation by enabling solid particles to gain enough energy to break free and disperse as gas.
The process of an ion forming intermolecular attractions with solvent particles is called?
This process is called solvation. Basically, it is a chemical process in which there is intermolecular attraction or combining of solvent molecules with the molecules or ions of a solute.
What is the process which particles move slowly enough for their attraction to bring them together to form a droplet of liquid?
The process is called condensation. When particles in a gas or vapor slow down enough, their attraction forces cause them to come together and form a droplet of liquid. This typically occurs when the temperature of the gas or vapor decreases, causing the particles to lose energy and move more slowly.
