SubscribersHow many subscribers the channel has now. The wave shows subscribers at each point of the period. The change is against the start of the period.43▼ 2.3 %−1 for the period
ViewsHow many views the posts published in the period have now. These are not views per day: MAX does not report how many views there were yesterday. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.38▲ 3.7 %was 37
ReactionsHow many reactions the posts published in the period have. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.0was 0
MentionsHow many times other channels mentioned the channel: links and reposts, excluding advertising posts. The bigger the circle, the more mentions at that point of the period. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.61▼ 19.6 %was 76with a subscription
RepostsHow many times other channels reposted this channel's posts (excluding advertising posts). Reposts are also counted as mentions. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.28▲ 12.3 %was 25after signing in
Average post reachHow many views one post gets on average. Only posts older than two days are counted: views of fresh posts are still growing. Points with fresh posts are dashed with hollow dots: the reach of all posts right now, it will still grow.5 478▲ 1.0 %was 5 421after signing in
ERRWhat share of subscribers sees an average post: average reach ÷ subscribers × 100 %. The line shows ERR at each point of the period, the dashed line — ERR of the previous period of the same length. Points with posts younger than two days are hollow dots on the dashed end of the line.28.9 %▼ 0.2 ppdashed line — was 29.0 %after signing in
Engagement ERHow often readers react to posts: reactions ÷ views × 100 %. The tick on the bar is the previous period.2.84 %▼ 0.2 pp
Posts per dayHow many posts are published per day on average. Each cell is a point of the period: the darker, the more posts per day. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.4.3▼ 10.8 %was 4.8after signing in
Ad shareWhat share of the period's posts looks like advertising: erid labeling, ad links and other signs. The scale shows the ad load by the quality index thresholds: up to 10 % — low, up to 25 % — moderate, up to 50 % — high, above — very high. A growing share is marked red.3.1 %▲ 0.3 pp
TrendTop — subscribers at the end of each point of the period; bottom — growth per point: green means more subscribers, red means fewer. Above the growth chart — the biggest gain and the biggest loss. MAX does not report how many people subscribed and unsubscribed separately.

Channel scoreA channel score from 0 to 100 made of five parts: audience, growth integrity, ad load, trust and calculation reliability. Each bar shows how many points the part earned out of its maximum. The index is recalculated every night; channels are compared with similar ones of the same category and size.
ReachHow many views the posts published at each point of the period have now (not views per day). The record is labeled; the point with today is paler — the day is not over yet. Average post reach — posts older than two days.
Views and reach
702 763views in the period▼ 10.4 %
Average post reach — 5 478 views (posts older than two days).
EngagementER — reactions divided by views, in percent — for the posts of each point of the period. The dashed line is ER for the whole period. The change is in percentage points against the previous period of the same length.
CitationsThe citation index (CI) shows how often and by which channels this channel is mentioned over the last 30 days, excluding advertising posts. The level is its place among similar channels. The line shows CI at each point of the period (for a week or month — the average over its days).
The citation index has not been calculated yet: it will appear after the nightly calculation once other channels mention the channel.
RhythmHow many posts are published on average in each hour of each weekday, Moscow time: the darker the cell, the more posts. “Best time” — the hours when posts older than two days have the highest average reach.

FormatsWhat the feed is made of. Each post has one format, by priority: repost, video, photo, link, text. The bar and percentages show the share of posts of each format; on the right — average reach of one post of the format (posts older than two days), the small bar compares it with the most viewed format.

On the right — average reach of one post of the format.
PostsEach dot is a post in the period: horizontally — publication date, vertically — views, dot size — reactions, color — format. This shows hits, flops and how reach changes. For large channels, the 100 most viewed posts and an even sample of the rest are shown — no more than 1,500 dots.

SummaryTotals for the selected period: how many posts were published, how many views and reactions they have now and the average post reach. Views are the current views of posts published on those days, not views per day. The change is against the same span before the period, if statistics cover it.

Viewstoday — the day is not over yetPoints with posts younger than two days are pale and dashed: their views are still growing.
AdsWhat share of the period's posts looks like advertising: erid labeling, ad links and other signs. The detector is cautious, so the real share is usually higher. The scale shows the ad load by the quality index thresholds. Below — the average reach of an ad post and a regular post, and who the channel advertises (sites that ad links lead to).
What worksPosts of the period with the most views. The bar shows views relative to first place. The preview is the post's image; for a post without an image — the channel avatar. Views are the post's current count.
RhythmHow many posts were published each day of the period (pale bars) and the 7-day average (line): you can see whether the channel is speeding up or slowing down. Today is not over yet, so its average is calculated up to yesterday.
Posts by day
Pale bars are days, the line is the 7-day average: you can see whether the channel is speeding up or slowing down

Data updated at 22:23 Moscow time. Views are the current counts of posts published on those days; average reach counts posts older than two days.
How the quality index is calculated
Привет, ребята! Мы немного притихли, но подготовка к ОГЭ не ждёт. Возвращаемся в работу с самой важной темы — расчётные задачи.
Именно задания 18, 19 и 22 (задачи) дают много баллов, но и вызывают больше всего паники.
Главное правило задач — никакой магии, только формулы: 🔹 n = m / M (количество вещества) 🔹 V = n × 22,4 (объём газа при н.у.) 🔹 ω = m(вещества) / m(раствора) × 100% (массовая доля)
Разберём типовую задачу (по типу задания 22):
Условие: Какой объём углекислого газа (н.у.) выделится при действии избытка соляной кислоты на 106 г 10%-ного раствора карбоната натрия (Na₂CO₃)?
Решаем по шагам:
1. Найдём массу чистого вещества. m(Na₂CO₃) = 106 г × 0,1 = 10,6 г
📝 Главный вывод для ОГЭ: Чем активнее металл и чем разбавленнее кислота, тем сильнее меняется степень окисления неметалла в кислоте (глубже восстановление).
Сохраняй себе, для успешного выполнения задания 9❤️
Кислоты-окислители — твой ключ к сложным реакциям!
Привет, будущие химики! 👋 Сегодня разбираем тему, которая часто вызывает ступор на экзамене, но на самом деле подчиняется четким правилам. Это кислоты-окислители.
🧪 Кто же они? Запомни двух главных «героев»: 1️⃣ HNO₃ (Азотная кислота) — в ЛЮБОЙ концентрации. 2️⃣ H₂SO₄ (Серная кислота) — ТОЛЬКО концентрированная.
⚠️ Важно: Разбавленная серная кислота ведет себя как обычная кислота (выделяет водород), а вот концентрированная — работает как окислитель за счет серы (S⁺⁶).
⚙️ Как это работает? В обычных кислотах окислителем является водород (H⁺¹ → H₂⁰). В кислотах-окислителях окислителем становится центральный атом (N или S), и он меняет свою степень окисления.
Все, кто готовится к экзамену, рано или поздно попадают на сайт ФИПИ. И знаете что? Это золотая жила.
ФИПИ — это официальные составители ОГЭ. И фишка в том, что на реальном экзамене заданиям из их банка попадаются точь-в-точь с теми же реакциями и формулировками. Прорешав банк, ты фактически знаешь, что будет на экзамене.
НО есть две огромные проблемы:
1. Там нет нормальной сортировки. Ты сидишь и просто листаешь сотни заданий подряд, не понимая логики. Нет разбивки по типам или сложности. 2. Там нет ответов. Ты решаешь, но не можешь проверить себя. Ошибся ты или нет? А если ошибся — где именно? В банке ответов нет.
Получается, что самый ценный ресурс превращается в хаос.
Что делать?
Именно поэтому на моем курсе мы не просто «проходим темы», а разбираем эти самые задания из банка ФИПИ.
Мы берем этот хаос и структурируем его: ✅ Учимся решать именно те типы задач, которые там есть. ✅ Разбираем логику и «ловушки» составителей. ✅ Проверяем каждый шаг, чтобы ты не просто нашел ответ, а понял, почему он правильный.
Мы превращаем «свалку заданий» в четкую систему подготовки.
Хочешь перестать блуждать в банке ФИПИ и начать понимать, что от тебя хотят на экзамене? Пиши в личку, расскажу, как попасть на курс. 👇
