Chemistry

1. The energy released during a chemical reaction is called:

Correct answer: D

Rationale: Exothermic means "outward heat," indicating energy is released during the reaction.

2. Which word is most closely associated with the adjective "ambiguous"?

Correct answer: B

Rationale: "Ambiguous" implies uncertainty or multiple interpretations, making "vague" its closest synonym.

3. A new medication claims to reduce allergy symptoms by 90%. A study is conducted where 100 participants with allergies take the medication, and 90 report symptom reduction. Should this be enough evidence to recommend the medication for everyone?

Correct answer: C

Rationale: : Comparing the medication group to a group receiving a placebo (inactive substance) would help isolate the medication's true effect and avoid attributing symptom reduction to other factors.

4. Which of Mendel's Laws states that alleles for a gene segregate during gamete formation?

Correct answer: B

Rationale: Rationale: The Law of Segregation, proposed by Gregor Mendel, states that alleles for a gene segregate during gamete formation. This means that each parent passes on only one allele for each gene to their offspring. This law explains how genetic diversity is maintained and how different combinations of alleles are generated in offspring. The Law of Independent Assortment (option A) states that alleles of different genes assort independently of each other during gamete formation. The Law of Dominance (option C) states that one allele can be dominant over another allele, affecting the phenotype. The Law of Probability (option D) is a general concept that describes the likelihood of a particular event occurring.

5. What property of a substance refers to its ability to undergo a chemical change and form new substances with different properties?

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, forming new substances with different properties.

6. A table top has dimensions of 75cm by 50cm. What is its perimeter if opposite sides are equal?

Correct answer: B

Rationale: Rationale: - Given that the table top has dimensions of 75cm by 50cm. - Since opposite sides are equal, the table top can be divided into two pairs of equal sides: 75cm and 50cm. - To find the perimeter, we add up all four sides: 75cm + 50cm + 75cm + 50cm = 250cm. - However, since opposite sides are equal, we only need to consider two sides: 75cm + 50cm = 125cm. - Therefore, the perimeter of the table top is 125cm + 125cm = 150cm. - Hence, the correct answer is B) 150cm.
