Question

use the following information to answer the next question. the following statements were made about solubility. 1 polar compounds dissolve in polar compounds. 2 compounds with hydrogen - bonding dissolve in water. 3 non - polar compounds dissolve in non - polar compounds. 4 non - polar compounds dissolve in water. 5 polar compounds will dissolve in octane, c8h18(l). 6 non - polar compounds will dissolve in octane, c8h18(l). 15. based on the solubility rules, which statements are correct: _, _, _ and _. (record your four - digit answer in the numerical - response section below.) your answer:

Explanation:

Step1: Recall solubility principle

Like - dissolves - like. Polar substances dissolve in polar solvents and non - polar substances dissolve in non - polar solvents.

Step2: Analyze statement 1

Polar compounds dissolve in polar compounds. This is in line with the like - dissolves - like principle, so it is correct.

Step3: Analyze statement 2

Water is a polar compound with hydrogen bonding. Compounds with hydrogen bonding can dissolve in water due to similar intermolecular forces, so it is correct.

Step4: Analyze statement 3

Non - polar compounds dissolve in non - polar compounds. This follows the like - dissolves - like rule, so it is correct.

Step5: Analyze statement 4

Water is polar and non - polar compounds do not dissolve in water as they have different intermolecular forces, so it is incorrect.

Step6: Analyze statement 5

Octane ($C_8H_{18}$) is non - polar. Polar compounds will not dissolve in octane as they are not like substances, so it is incorrect.

Step7: Analyze statement 6

Non - polar compounds will dissolve in octane ($C_8H_{18}$) since both are non - polar, so it is correct.

The correct statements are 1, 2, 3, 6. Recording the answer as a four - digit number, if we assume 1 is the first digit, 2 is the second, 3 is the third and 6 is the fourth, the four - digit number is 1236.

Answer:

1236
