Before answering, candidates must fill in their name and candidate number on the test paper and answer sheet, and paste the candidate number barcode in the designated position on the answer sheet. 2. When answering multiple-choice questions, after selecting the answer for each question, use a pencil to shade the corresponding answer choice on the answer sheet. If modification is needed, erase it cleanly with an eraser before shading other answer choices. When answering non-multiple-choice questions, write the answers on the answer sheet. Answers written on this test paper are invalid. 3. After the exam, hand in both this test paper and the answer sheet. **Possible Relative Atomic Masses:** * H: 1 * C: 12 * O: 16 * F: 19 * Cl: 35.5 * K: 39 * Cu: 64 * Zn: 65 * In: 115 --- **Section: Multiple Choice Questions (一、选择题)** * **Instructions:** This section has 14 questions, each worth 3 points, totaling 42 points. For each question, only one of the four given options meets the requirements. **Question 1:** * **Question Stem:** Chemistry is closely related to life and production. From a chemical perspective to understand the world, which of the following statements is incorrect? * **Options:** * A. Huangshan Welcoming Pine takes root in rock crevices, creating miracles with astonishing toughness and rigidity. Pine wood is rich in carbohydrates. * B. The 2023 Nobel Prize in Chemistry was awarded for quantum dot research. Silicon quantum dots with a diameter of 2-20 nm belong to colloids. * C. Nature online published the precise synthesis of aromatic carbon rings C$_{10}$ and C$_{14}$ by Tongji University's College of Material Science and Engineering. The two are allotropes. * D. New ceramic silicon carbide can not only be used as high-temperature structural materials but also as high-temperature semiconductor materials. **Question 2:** * **Question Stem:** Which of the following chemical terms or diagrams is expressed correctly? * **Options:** * A. Electron cloud contour map of valence electrons of ground state magnesium atom: * **Diagram Description:** A 3D Cartesian coordinate system is shown with X and Y axes. An electron cloud is depicted as four lobes extending outwards from the origin, positioned symmetrically between the X and Y axes, characteristic of a d-orbital (e.g., d$_{xy}$). * B. Space-filling model * **Diagram Description:** A space-filling model of a molecule is shown, consisting of one large central sphere bonded to four smaller identical spheres arranged tetrahedrally around it. * **Accompanying Text:** "既可以表示甲烷分子，也可以表示四氯化碳分子" (can represent both methane molecule and carbon tetrachloride molecule). * C. In CH$_{3}$COOH molecule, the type of covalent bond formed between carbon and oxygen atoms is sp$^{3}$-pσ bond. * D. Monomers of synthetic phenolic resin (H-[Benzene ring with -CH$_{2}$- branching]-OH) are [Benzene ring with -OH] and HCHO. **Question 3:** * **Question Stem:** Which of the following experimental designs is correct and can achieve the corresponding experimental purpose? (Some clamping devices are omitted) * **Diagrams:** * **Diagram 甲 (Jia):** * **Type:** Gas reaction and collection apparatus. * **Elements:** A test tube containing "Cu" (Copper) and "浓硫酸" (concentrated sulfuric acid) is set up with a small hole at the bottom. A delivery tube from the side arm of the test tube is immersed in a beaker labeled "酸性 KMnO$_{4}$溶液" (acidic KMnO$_{4}$ solution). A balloon is attached to the top of the test tube. * **Diagram 乙 (Yi):** * **Type:** Gas preparation and detection apparatus. * **Elements:** A test tube containing "NH$_{4}$Cl 固体" (NH$_{4}$Cl solid) and "P$_{2}$O$_{5}$" (P$_{2}$O$_{5}$) is heated by a burner. A delivery tube leads from the test tube to a U-tube containing "碱石灰" (soda lime). After the U-tube, the gas path splits: one path leads to "湿润的蓝色石蕊试纸" (moist blue litmus paper), and the other leads to "干燥的酚酞试纸" (dry phenolphthalein test paper). * **Diagram 丙 (Bing):** * **Type:** Gas collection apparatus using liquid displacement. * **Elements:** A gas inlet tube extends into a beaker, with its end positioned near the bottom. The beaker contains two immiscible liquid layers: "水" (water) at the top and "四氯化碳" (carbon tetrachloride) at the bottom. "氨气" (ammonia gas) is shown entering through the gas inlet tube. * **Diagram 丁 (Ding):** * **Type:** Gas preparation and property testing apparatus. * **Elements:** A round-bottom flask contains "碳酸钙" (calcium carbonate). "浓盐酸" (concentrated hydrochloric acid) is added via a thistle funnel into the flask. A delivery tube leads from the flask to a gas washing bottle containing "饱和NaHCO$_{3}$溶液" (saturated NaHCO$_{3}$ solution). Another delivery tube connects the washing bottle to a beaker containing "硅酸钠溶液" (sodium silicate solution).
