ATI TEAS English and Language Usage

1. The top-secret blueprints were for an intergalactic spaceship. Which of the following is the meaning of the prefix 'inter-' as used in the sentence above?

Correct answer: A

Rationale: The prefix 'inter-' means 'among' or 'between,' which is most fitting in the context of 'intergalactic' as 'among galaxies.' 'Below,' 'around,' and 'above' do not convey the correct meaning of the prefix 'inter-' in this context.

2. What type of bond is formed when electrons are transferred between atoms?

Correct answer: D

Rationale: The correct answer is 'D: Ionic bond.' An ionic bond is formed when electrons are transferred between atoms. In an ionic bond, one atom donates electrons to another atom, resulting in the formation of positively and negatively charged ions that are attracted to each other, creating a strong bond. Choice A, 'Transfer bond,' is incorrect because there is no common term known as a 'Transfer bond' in chemistry. Choice B, 'Static bond,' is incorrect as it does not describe the process of electron transfer between atoms. Choice C, 'Covalent bond,' is incorrect because in a covalent bond, electrons are shared between atoms rather than transferred outright, making it different from an ionic bond.

3. What information can be obtained from the mass number of an element?

Correct answer: B

Rationale: The mass number of an element represents the total number of protons and neutrons in the nucleus. This information is crucial for determining the atomic mass of the element and understanding its stability and isotopes. The number of protons in the nucleus (option A) is represented by the atomic number, not the mass number. The number of electrons in the valence shell (option C) is related to the element's position in the periodic table and its chemical properties, but it is not directly determined by the mass number. The element's chemical reactivity (option D) is influenced by the number and arrangement of electrons in the atom's energy levels, not by the mass number.

4. Which of the answer choices best describes the appropriateness of Mara's data sample?

Correct answer: A

Rationale: The correct answer is A. Mara's data sample is biased because it only includes teachers who are immersed in the technology field, specifically those teaching a computer software course. This limits the perspectives gathered, leading to skewed results. Choice B is incorrect because the issue lies in the sample composition, not its size. Choice C is incorrect as a large sample size does not necessarily indicate bias. Choice D is incorrect as the sample's bias compromises the study's validity.

5. The van't Hoff factor (i) accounts for the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be...

Correct answer: D

Rationale: The van't Hoff factor (i) represents the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be more than 1 because it breaks apart into more particles than the original compound. This is due to complete dissociation leading to an increase in the number of particles in solution, resulting in i being greater than 1. Choice A is incorrect as a compound that dissociates completely will not have an i value of 0. Choice B is incorrect because when a compound dissociates completely, the van't Hoff factor is not less than 1. Choice C is incorrect as a compound that dissociates completely will not have an i value of 1, but rather more than 1 due to the increased number of particles in solution.
