Identifying image contents and answering questions
The user has shared a Russian worksheet on gypsum binders and lime production, with questions 1-7. I can already make out the text in the image preview, so I should be able to provide answers directly. I’ll work through the visible content to fill in the answers, without needing extra processing.
Transcribing the worksheet questions
The worksheet is about the "Technology of production of gypsum binders and building lime." It includes questions like:
- Pick the correct answer (types of binders).
- Finish the definition for a product of limestone heating.
- Another multiple-choice question about quicklime.
- Provide answers for two products derived from quicklime.
- More multiple-choice on slaking temperature.
- Multiple-choice on low-burn gypsum binders composition.
Answering building materials questions
The questions ask about different types of binders. For the first one, hydraulic binders set in air and continue hardening in water, so the answer is "А) Гидравлические" (hydraulic). The second question is about the product of burning calcium-magnesium carbonates—this is lime ("известь"). I’ll go with "известь" or "строительная известь" for accuracy.
Answering questions about quicklime and slaked lime
In the third question, quicklime (unslaked lime) is made of CaO, so the answer is A) CaO. For the fourth question, quicklime ("комовая негашеная известь") is used to make two products: lime putty ("известковое тесто") and hydrated lime. I’ll choose these as the two products.
Answering questions with details on lime and gypsum binders
For question 4, the two products made from quicklime are А) гидратную известь (hydrated lime) and Б) известковое тесто (lime putty). For question 5, high-exothermic lime slaking temperature is above 70°C, so the answer is В) выше 70°С. For question 6, low-burned gypsum binders are primarily made of Б) полугидрат гипса (plaster of Paris), and for
