Chemistry HESI A2 Quizlet Questions
Question 1 of 5
What are the three types of radiation?
Correct Answer: A
Rationale: The correct answer is A: Alpha, beta, gamma. Alpha radiation consists of helium nuclei, beta radiation includes electrons or positrons, and gamma radiation is electromagnetic radiation. This is correct as it covers all three types of radiation commonly encountered in nuclear physics. Choice B is incorrect as delta radiation is not a recognized form of radiation. Choice C is incorrect as delta and epsilon are not types of radiation, and choice D is incorrect as it does not include the correct types of radiation.
Question 2 of 5
What type of chemical reaction involves the reaction of a compound with oxygen?
Correct Answer: C
Rationale: The correct answer is C: Combustion. Combustion is a chemical reaction where a compound reacts with oxygen to produce heat, light, and often carbon dioxide and water. In this type of reaction, oxygen is a reactant and typically a hydrocarbon or organic compound is the fuel. Decomposition involves a compound breaking down into simpler substances, synthesis is when two or more substances combine to form a more complex compound, and single replacement is when one element replaces another in a compound. Combustion specifically involves the reaction with oxygen, making it the correct choice in this scenario.
Question 3 of 5
What are the horizontal rows of the periodic table called?
Correct Answer: A
Rationale: The correct answer is A: Periods. Periods are the horizontal rows in the periodic table that represent the number of electron shells an element has. Each period corresponds to the principal energy level of the element. Families (Choice B) are the vertical columns of the periodic table that share similar properties. Groups (Choice C) are also vertical columns that share similar chemical properties. Columns (Choice D) are not a term used in the context of the periodic table. Therefore, the correct term for the horizontal rows in the periodic table is periods.
Question 4 of 5
Which intermolecular force is the strongest?
Correct Answer: C
Rationale: The correct answer is C: Hydrogen bonding. Hydrogen bonding is the strongest intermolecular force due to the high electronegativity difference between hydrogen and elements like nitrogen, oxygen, or fluorine, leading to a strong partial positive charge on hydrogen. This allows for a strong attraction with the partial negative charge on the electronegative atom of another molecule. Dipole interactions (A) are weaker than hydrogen bonding, dispersion forces (B) are the weakest intermolecular force, and Van der Waals forces (D) are a broad term that encompasses all intermolecular forces, including hydrogen bonding.
Question 5 of 5
What are the three types of radiation?
Correct Answer: A
Rationale: The correct answer is A: Alpha, beta, gamma. Alpha radiation consists of helium nuclei, beta radiation includes electrons or positrons, and gamma radiation is electromagnetic radiation. This is correct as it covers all three types of radiation commonly encountered in nuclear physics. Choice B is incorrect as delta radiation is not a recognized form of radiation. Choice C is incorrect as delta and epsilon are not types of radiation, and choice D is incorrect as it does not include the correct types of radiation.
