answer the following question: QUESTION 4: What does it mean if a compound has a solubility of 15g in 100g of water at 0 degrees Celcius? A) 100 g of the compound will dissolve in 15 g of water at 0 degrees celcius B)15 g of the compound will dissolve in 100g of water at 0 degrees Celcous C) the compound will not dissolve until 15g of it are present D) the compound will dissolve only if water temperature is 0 degrees celcius

It means that up to 15 g of the compound will dissolve in 100 g of water at 0 deg C.

B) is the correct answer. At higher temperatures, more will probably dissolve.

E) It means the compound will dissolve only if you perform a magic trick with a temperature of exactly 0 degrees Celsius. Just add a little abracadabra and voila, it will disappear into the water! But remember, it's all just a bit of magical chemistry.

To determine the meaning of a solubility value, we need to understand what solubility represents. Solubility is the maximum amount of a substance that can dissolve in a given amount of solvent at a specific temperature.

In this case, the solubility of the compound is given as 15g in 100g of water at 0 degrees Celsius. This means that at 0 degrees Celsius, 15 grams of the compound can dissolve in 100 grams of water.

Therefore, the correct answer is B) 15 g of the compound will dissolve in 100g of water at 0 degrees Celsius.

To answer the question, we need to understand what solubility means in the context of a compound dissolving in water. Solubility refers to the maximum amount of a substance that can dissolve in a solvent at a given temperature.

In this case, we are given that the solubility of the compound is 15 g in 100 g of water at 0 degrees Celsius. This means that at 0 degrees Celsius, 15 grams of the compound can dissolve in 100 grams of water.

Now let's evaluate each option:

A) 100 g of the compound will dissolve in 15 g of water at 0 degrees Celsius: This statement contradicts the definition of solubility. Solubility refers to the amount of the compound that can dissolve in a fixed amount of water, not the other way around. Therefore, this option is incorrect.

B) 15 g of the compound will dissolve in 100 g of water at 0 degrees Celsius: This statement aligns with the definition of solubility. It states that the compound can fully dissolve when 15 grams of it are mixed with 100 grams of water at 0 degrees Celsius. Therefore, this option is correct.

C) The compound will not dissolve until 15 g of it is present: This statement suggests that the compound will not dissolve at all until a specific amount of it is reached. This contradicts the given solubility value, which implies that some amount of the compound can dissolve in water at 0 degrees Celsius. Thus, this option is incorrect.

D) The compound will dissolve only if the water temperature is 0 degrees Celsius: This statement suggests that the solubility of the compound is dependent solely on the temperature being 0 degrees Celsius. However, the given solubility value of 15 g in 100 g of water at 0 degrees Celsius does not imply exclusivity to that temperature. Therefore, this option is incorrect.

In conclusion, the correct answer is B) 15 g of the compound will dissolve in 100 g of water at 0 degrees Celsius.
