The phrase “a buzz in the world of chemistry” has appeared in several English proficiency exams (notably IELTS Academic Reading) and science journalism pieces. It typically refers to a breakthrough, controversy, or exciting discovery that creates widespread discussion among chemists. This article provides a you would expect from such a passage, including question types like True/False/Not Given , Matching Headings , Sentence Completion , and Short Answer Questions .
Paragraph D – The biggest buzz in popular media, though, has been “artificial photosynthesis.” Researchers at the Joint Center for Artificial Photosynthesis (JCAP) have developed devices that mimic leaves, splitting water into hydrogen and oxygen using sunlight. The goal is carbon-neutral fuel. While efficiencies remain below 5%, the buzz is justified: if scaled, it could replace fossil fuels. Skeptics note the high cost of rare metal catalysts like iridium, but recent breakthroughs in metal-organic frameworks (MOFs) offer cheaper alternatives. a buzz in the world of chemistry reading answers with

| Statement | Answer | Explanation | |-----------|--------|--------------| | 1. Single-atom catalysts were first created using platinum nanoparticles. | | Paragraph B says SACs use isolated atoms, not nanoparticles. The first demonstration used platinum atoms, not nanoparticles. | | 2. Mechanochemistry has been universally accepted as reproducible. | False | Paragraph C states critics argue it lacks reproducibility; a 2019 study only partially settled the debate. Not universally accepted. | | 3. Artificial photosynthesis devices currently operate at over 10% efficiency. | False | Paragraph D: “efficiencies remain below 5%.” So 10% is false. | | 4. Machine learning models can perfectly predict stereochemistry. | False | Paragraph E: “it struggles with stereochemistry and novel substrates” – so not perfect. | | 5. The public has always viewed chemistry with enthusiasm. | Not Given | Paragraph F mentions public perception “tainted by pollution” but does not say “always.” No historical data given. | Paragraph D – The biggest buzz in popular
