Chemistry

1. How can you predict the charge of an ion formed by an element based on its position on the periodic table?

Correct answer: B

Rationale: The group number of an element on the periodic table often indicates the typical ionic charge it will form. Elements in the same group tend to have similar chemical properties, including the tendency to gain or lose electrons to achieve a stable electron configuration. This predictable pattern allows us to anticipate the charge of an ion formed by an element based on its position in the periodic table.

2. Which of the following glands is NOT directly controlled by the pituitary gland?

Correct answer: C

Rationale: The correct answer is C. The pituitary gland is often referred to as the 'master gland' because it secretes hormones that control the functions of other endocrine glands. The thyroid gland (A), adrenal glands (B), and parathyroid glands (D) are directly controlled by the pituitary gland through the release of specific hormones. However, the pancreas, specifically the islets of Langerhans (C), is not directly controlled by the pituitary gland. The pancreas is regulated by hormones such as insulin and glucagon, which are not secreted by the pituitary gland. Therefore, option C is the correct answer as it is not directly influenced by the pituitary gland's hormonal regulation.

3. In the reaction 4Al + 3O2 → 2Al2O3, what is the mole ratio of aluminum to oxygen?

Correct answer: a

Rationale: The coefficients in the balanced equation represent the mole ratio, which is 4 moles of Al to 3 moles of O2.

4. What property of a wave remains unchanged when it passes from one medium to another with the same speed?

Correct answer: d

Rationale: The speed of a wave remains constant when passing from one medium to another with the same speed.

5. "Ironic" and "serious" are:

Correct answer: B

Rationale: "Ironic" means the opposite of "serious."

6. Which of the following sentences uses the most formal language?

Correct answer: C

Rationale: The sentence uses more complex vocabulary ("cinematic experience") and avoids slang ("awesome," "flick").
