4. Dissolution processes with negative heats or solution are ______ processes.

1. I don't know. Perhaps "goes forward".

2. anyathing could go here.
3. colloid
4. exothermic.

Thanks and yeah idk those questions are pretty vague but thank you so much anyway!

1. When the energy released by the formation of solute-solvent attractions is greater than the energy absorbed by overcoming solute-solute and solvent-solvent attractions, the dissolving process occurs.

2. Mixtures are classified according to their composition.
3. A homogeneous mixture that contains particles in a dispersed phase that do not settle out is a colloid.
4. Dissolution processes with negative heats of solution are exothermic processes.

1. When the energy released by the formation of solute-solvent attractions is greater than the energy absorbed by overcoming solute-solute and solvent-solvent attractions, the dissolving process happens spontaneously.

To understand this concept, you can consider the following steps:
- In a dissolving process, solute particles separate from each other, while solvent particles surround and interact with the solute particles.
- To overcome the attractive forces between solute particles (solute-solute attractions) and between solvent particles (solvent-solvent attractions), energy must be absorbed.
- However, when solute particles are surrounded by solvent particles and form attractions (solute-solvent attractions), energy is released.
- If the energy released by the formation of solute-solvent attractions is greater than the energy absorbed by overcoming solute-solute and solvent-solvent attractions, the overall energy change will be negative, indicating a spontaneous dissolving process.

2. Mixtures are classified according to their composition.

To determine the composition of a mixture, you can analyze its components in terms of their molecular or elemental makeup. Based on the composition, mixtures can be classified into various categories. Some common classifications include:
- Homogeneous mixtures: These mixtures have uniform composition throughout and cannot be visually distinguished, such as solutions.
- Heterogeneous mixtures: These mixtures have non-uniform composition and can be visually distinguished, such as suspensions or emulsions.
- Colloids: These mixtures exhibit intermediate properties between homogeneous and heterogeneous mixtures, where particles are evenly dispersed but not dissolved, leading to scattering of light.

3. A homogeneous mixture that contains particles in a dispersed phase that do not settle out is called a colloid.

To identify a colloid, you need to consider the following characteristics:
- A colloid is a type of mixture where particles in a dispersed phase are evenly distributed throughout a continuous medium.
- The dispersed phase consists of particles that are larger in size than individual molecules but smaller than those found in suspensions.
- Unlike suspensions, which are heterogeneous mixtures that eventually settle out due to gravity, colloids have particles that do not settle out and remain dispersed.
- Colloids often exhibit unique properties, such as opacity, opalescence, or Tyndall effect (light scattering) due to the dispersed particles.

4. Dissolution processes with negative heats of solution are exothermic processes.

To determine if a dissolution process has a negative heat of solution (exothermic) or positive heat of solution (endothermic), you can follow these steps:
- Measure the heat change during the dissolution process using calorimetry or enthalpy measurements.
- If the measured heat change indicates a decrease in energy (exothermic), the dissolution process has a negative heat of solution.
- Exothermic processes release heat to the surroundings, usually accompanied by a temperature increase.
- On the contrary, if the measured heat change indicates an increase in energy (endothermic), the dissolution process has a positive heat of solution.
- Endothermic processes absorb heat from the surroundings, usually accompanied by a temperature decrease.
