Chemistry

1. What is the term for a hydrocarbon chain with no double or triple bonds between carbon atoms?

Correct answer: A

Rationale: A saturated hydrocarbon chain has only single bonds between carbon atoms. The other choices are associated with unsaturation or aromaticity.

2. In physics, what term describes the resistance of an object to changes in its motion?

Correct answer: A

Rationale: Inertia is the term that describes the resistance of an object to changes in its motion. This property is described by Newton's First Law of Motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force. Momentum (B) is the product of an object's mass and velocity, gravity (C) is the force that attracts objects towards each other, and kinetic energy (D) is the energy an object possesses due to its motion.

3. A new drug successfully treats a disease in mice. This suggests the drug will also be effective in humans. True or False? False. Animal models don't always perfectly translate to humans due to biological differences. Further testing in humans is crucial before drawing conclusions about safety and efficacy. A conclusion based on scientific evidence should be:

Correct answer: B

Rationale: Scientific conclusions should always be open to revision and further testing as new evidence emerges. Science is a dynamic process that involves continuous questioning, testing, and refining of ideas based on the most current evidence available. It is essential to remain open-minded and willing to adjust conclusions in light of new information to ensure the most accurate and reliable understanding of the natural world.

4. What is the main function of valence electrons in chemical bonding?

Correct answer: B

Rationale: They are involved in forming bonds with other atoms. Valence electrons occupy the outermost energy level and are readily involved in attracting other atoms through sharing or transferring electrons, forming chemical bonds.

5. The pH scale is used to indicate the concentration of:

Correct answer: A

Rationale: The pH scale measures the concentration of hydrogen ions in a solution, indicating acidity or basicity.

6. What happens to the potential energy of an object when it is lifted higher above the ground?

Correct answer: C

Rationale: When an object is lifted higher above the ground, its potential energy increases because the higher the object is lifted, the greater its potential energy due to the increased distance from the ground. This is in accordance with the formula for gravitational potential energy, which is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height above the reference point.
