-If I do not get these answers correct, could you explain as to why I wasn't right? Thank you so much<3

the 1st three are the ones that apply

4th one ... think of opening a warm soda can ... gas is out of solution

Ahhh, ok! Gotcha. Thank you so much lovieeee!

The correct statements regarding solubility are:

1. Pressure affects the solubility of gaseous solutes.
2. Solubility is often expressed in grams of solute per 100 g of solvent.
3. The solubility of most gases increases as the temperature increases.

Explanation:
1. Pressure affects the solubility of gaseous solutes because an increase in pressure leads to more gas molecules being forced into the solvent, resulting in a higher solubility.

2. Solubility is commonly expressed in grams of solute per 100 g of solvent. This is a way to standardize the measurement and allows for easy comparison between different solvents and solutes.

3. The solubility of most gases increases as the temperature increases. This is because higher temperatures provide greater energy to the gas molecules, allowing them to overcome intermolecular forces and dissolve more readily in the solvent.

The statement "The solubility of most solid substances increases as the temperature of the solvent increases" is incorrect. While this is true for some solid substances, it is not a general rule. The solubility of solid substances can vary widely with temperature depending on the specific properties of the solute and solvent. Some solutes may become less soluble with increasing temperature.

The correct answers are:

- Pressure affects the solubility of gaseous solutes
- Solubility is often expressed in grams of solute per 100 g of solvent
- The solubility of most gases increases as the temperature increases

Explanation of each statement:

1. The solubility of most solid substances increases as the temperature of the solvent increases:
This statement is not true. In general, the solubility of solid substances tends to increase with an increase in temperature, following the principle that most reactions proceed faster at higher temperatures. However, there are exceptions to this rule, such as the solubility of some salts that decreases with temperature. So, it's important to check specific solubility data for different substances.

2. Pressure affects the solubility of gaseous solutes:
This statement is true. The solubility of a gas in a liquid increases with increasing pressure. This relationship is described by Henry's Law, which states that the solubility of a gas is directly proportional to the partial pressure of that gas above the liquid.

3. Solubility is often expressed in grams of solute per 100 g of solvent:
This statement is true. Solubility is commonly expressed as the amount of solute (the substance being dissolved) in a given amount of solvent. The typical unit used is grams of solute per 100 grams of solvent (g/100g). Other units, such as moles per liter (mol/L), can also be used depending on the context.

4. The solubility of most gases increases as the temperature increases:
This statement is true. In general, the solubility of gases in a liquid tends to decrease with increasing temperature. This can be explained by the fact that as temperature increases, the kinetic energy of gas molecules also increases, causing them to escape the liquid more readily. However, there are exceptions, such as the solubility of carbon dioxide in water, which actually increases with temperature due to specific interactions between the gas and the solvent molecules.

If your answers were not correct, it might be due to a misunderstanding of the concepts or lack of specific knowledge about solubility. It's always a good practice to review the relevant scientific principles and check specific solubility data for different substances to ensure accurate answers.
