20 posts held, back to 2 February 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 23 July 2026. An engagement rate over an empty window would be a number about nothing.
117 reactions across 14 posts, in 7 distinct kinds. The most used accounts for 35.9% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 14 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 117 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 20 most recent posts we hold, published 2 February 2026 to 23 July 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.
7. Частичный гидролиз невосстанавливающего олигосахарида А дает смесь мальтозы и сахарозы. Укажите последовательность остатков моносахаридов в олигосахариде (без структурных формул), если масса продуктов полного гидролиза 16.65 г А оказалась больше массы А на 1.35 г. Найдите объем 3%-ной бромной воды с плотностью 1 г/мл, которую сможет обесцветить полученная смесь продуктов. Рассчитайте массу уксусного ангидрида, кот…

6. Навеску дисульфида железа(II) FeS₂ полностью растворили в избытке азотной кислоты с концентрацией 7 моль/л и плотностью 1.197 г/мл. Образовался раствор X и выделилось 22.00 л (1 атм, 298 К) смеси оксидов азота(II) и (IV), причем после пропускания этой смеси в избыток разбавленного холодного раствора гидроксида калия ее объем уменьшился в 3 раза, а в растворе образовались две соли. Мольное соотношение атомов железа…

5. Запишите уравнения реакций, соответствующих приведенным ниже превращениям, укажите условия их протекания. Пользуйтесь структурными формулами органических веществ при записи реакций. (7 баллов) С₇H₁₆ → X₁ → С₇H₆Cl₂ → X₂ → С₉H₁₁OMgBr → X₃ → С₉H₁₁ONa → С₁₀H₁₄O Решение: Определим неизвестные вещества. Исходное вещество C₇H₁₆ — гептан. В ходе превращений образуется бензальхлорид, затем через бензальдегид и реактив…

Сегодня у нас на очереди два задания - цепочки. Одна неорганическая, другая - органическая.
3. Константа диссоциации K уксусной кислоты в водном растворе зависит от температуры следующим образом: lg K = –1170/T – 0.0134T + 3.1649 (температура в К). Рассчитайте константу диссоциации при 25°C и степень диссоциации уксусной кислоты, а также величину pH ее 0.001 М раствора. Чему равна молярная концентрация HBr в растворе с тем же значением pH?

UPD. Осталось одно место и мы закрываем запись. 🟢Открыта запись на платные пробники ДВИ по химии и биологии 19 июня в 11.00 ➡️Записаться и задать вопросы @postupivMSUbot Поступи в МГУ Проголосовать за канал
💚💚💚💚💚💚 С 16 июня по 16 июля стартует интенсив по подготовке к ДВИ по химии. Он разбит на 10 занятий по 3 часа каждое. Будут разобраны темы, которые не изучаются при подготовке к ЕГЭ: углубленная общая химия, некоторые дополнительные главы органической химии и более сложные типы расчетных задач. 💚Подробную программу можно посмотреть в прикрепленном файле. Каждое занятие включает в себя теорию и практику - в ходе …
Showing the 12 most recent of 20 posts we hold for @kolba_chem. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Republishes
Channels on the register whose posts this channel has forwarded.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Named by 2 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
Names
Channels on the register whose handles appear in this channel's posts.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
@kolba_chem named 1 handle that resolve to nothing today. That is a fact about the reference, not necessarily a fact about the handle’s history — see the two groups below.
Most of these may never have existed as a live channel at all. A handle a channel names can be a typo, an aspirational name nobody registered, or a channel that was already gone before this one ever mentioned it. Unless a row below is marked evidenced, all we know is that it references a handle that is not a live channel today — not that anything “died”. How this is measured.
References a handle that is not a live channel — we have no record it ever was one.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 22 August 2026 — this entry's latest reading, not the date you are reading this.
