Программа обучения становится в разы сложнее и объемнее. Кроме того, полным ходом идет подготовка к экзаменам. Не все школьники справляются с такими нагрузками. Многие, пытаясь сосредоточиться на нескольких задачах сразу, допускают повсюду промахи. Особенно сложно нагнать потом упущенные навыки по химии, так как эта наука весьма специфична. Поэтому лучше сразу предотвратить всякие недоразумения. Для этого достаточно воспользоваться справочником <strong>ГДЗ по Химии 9 класс Учебник Рудзитис, Фельдман (Просвещение, 2016 г.)</strong>. </p> <p> На девятом году обучения ученикам предстоит учить такие темы как: </p> <ol> <li>Окислительно-восстановительные реакции.</li> <li>Характеристика кислорода и серы.</li> <li>Сероводород. Сульфиды.</li> <li>Соли аммония.</li> <li>Фосфорная кислота и её соли.</li> <li>Химические свойства углерода. Адсорбция, и т.д.</li> </ol> <p> Основные сложности возникают с составлением уравнений реакций, так как некоторые учащиеся не могут запомнить, что именно для этого надо. На уроках они списывают все с доски и не особо задумываются над тем, каким образом учитель приходит тем или иным выводам. Неудивительно, что дома подростки не могут повторить все продемонстрированные в классе схемы. Решебник позволит им разобраться во всех деталях и без всяких трудностей решать заданные номера. </p> <h2> ГДЗ - лучшее решение проблем </h2> <p> Химия пригодится ученикам как для получения многих профессий, так и для решения бытовых вопросов. Это изначально кажется, что знать непростые соединения и вещества в принципе не обязательно, ведь у ребят нет осознания того, зачем именно они все это учат. Таким образом могут возникнуть многочисленные пробелы, которые помешают правильно воспринимать последующий материал. <strong>Решебник к учебнику по химии за 9 класс Рудзитис Г.Е., Фельдман Ф.Г. (ФГОС)</strong> позволит быстро и качественно освоить предмет. </p> <p> Используя справочник для систематических занятий, ученики получат возможность: </p> <ol> <li>улучшить качество домашних заданий;</li> <li>своевременно находить и устранять ошибки;</li> <li>тщательно разбирать непонятные темы;</li> <li>заранее готовиться к многочисленным проверочным испытаниям.</li> </ol> <p> Работать с решебником подростки могут в удобном для себя темпе, так как издание доступно онлайн и открыть его легко с любого гаджета, подключенного к Интернету. Уделяя тренировкам хотя бы несколько минут в день, отстающие от программы учащиеся не только нагонят одноклассников, но и продвинутся вперед, что обеспечит им хорошие оценки и похвалу учителя. </p> <h2> Ответы из решебника - надежная помощь </h2> <p> Хоть на уроках учителя и стараются всячески донести до своих подопечных все тематические нюансы, но по факту нужная информация откладывается в памяти очень небольшого процента ребят.

Программа обучения становится в разы сложнее и объемнее. Кроме того, полным ходом идет подготовка к экзаменам. Не все школьники справляются с такими нагрузками. Многие, пытаясь сосредоточиться на нескольких задачах сразу, допускают повсюду промахи. Особенно сложно нагнать потом упущенные навыки по химии, так как эта наука весьма специфична. Поэтому лучше сразу предотвратить всякие недоразумения. Для этого достаточно воспользоваться справочником <strong>ГДЗ по Химии 9 класс Учебник Рудзитис, Фельдман (Просвещение, 2016 г.)</strong>. </p> <p> На девятом году обучения ученикам предстоит учить такие темы как: </p> <ol> <li>Окислительно-восстановительные реакции.</li> <li>Характеристика кислорода и серы.</li> <li>Сероводород. Сульфиды.</li> <li>Соли аммония.</li> <li>Фосфорная кислота и её соли.</li> <li>Химические свойства углерода. Адсорбция, и т.д.</li> </ol> <p> Основные сложности возникают с составлением уравнений реакций, так как некоторые учащиеся не могут запомнить, что именно для этого надо. На уроках они списывают все с доски и не особо задумываются над тем, каким образом учитель приходит тем или иным выводам. Неудивительно, что дома подростки не могут повторить все продемонстрированные в классе схемы. Решебник позволит им разобраться во всех деталях и без всяких трудностей решать заданные номера. </p> <h2> ГДЗ - лучшее решение проблем </h2> <p> Химия пригодится ученикам как для получения многих профессий, так и для решения бытовых вопросов. Это изначально кажется, что знать непростые соединения и вещества в принципе не обязательно, ведь у ребят нет осознания того, зачем именно они все это учат. Таким образом могут возникнуть многочисленные пробелы, которые помешают правильно воспринимать последующий материал. <strong>Решебник к учебнику по химии за 9 класс Рудзитис Г.Е., Фельдман Ф.Г.

№1 (с. 180)
Условие. №1 (с. 180)
скриншот условия
1. Соединения углерода и водорода называют
1) углеводами
2) карбидами
3) карбоновыми кислотами
4) углеводородами
Решение. №1 (с. 180)
Решение 2. №1 (с. 180)
Для того чтобы определить правильный ответ, необходимо проанализировать каждый из предложенных терминов и соотнести его с определением "соединения углерода и водорода".
1) углеводами
Углеводы (или сахариды) — это обширный класс органических соединений, которые, помимо атомов углерода и водорода, обязательно содержат в своем составе атомы кислорода. Часто их общая формула может быть представлена как $C_m(H_2O)_n$, что исторически и дало им название "угле-воды". Примером может служить глюкоза ($C_6H_{12}O_6$) или сахароза ($C_{12}H_{22}O_{11}$). Поскольку в их состав входит кислород, этот вариант не является верным.
2) карбидами
Карбиды — это бинарные соединения углерода с элементами, имеющими меньшую электроотрицательность, как правило, с металлами и некоторыми неметаллами. Примеры: карбид кальция ($CaC_2$), карбид кремния ($SiC$), карбид железа (цементит, $Fe_3C$). Эти соединения не содержат водорода и не являются соединениями углерода с водородом. Следовательно, этот вариант неверен.
3) карбоновыми кислотами
Карбоновые кислоты — это класс органических соединений, отличительной чертой которых является наличие одной или нескольких карбоксильных групп ($-COOH$). Эта функциональная группа содержит атомы кислорода. Таким образом, карбоновые кислоты состоят из углерода, водорода и кислорода. Пример — уксусная кислота ($CH_3COOH$). Этот вариант также является неверным.
4) углеводородами
Углеводороды — это, по определению, класс органических соединений, состоящих исключительно из атомов двух химических элементов: углерода ($C$) и водорода ($H$). Само название этого класса является комбинацией слов "углерод" и "водород", что точно отражает их состав. К углеводородам относятся алканы (метан $CH_4$), алкены (этилен $C_2H_4$), алкины (ацетилен $C_2H_2$), арены (бензол $C_6H_6$) и другие. Это определение полностью соответствует условию вопроса.
Таким образом, единственно верным вариантом является 4.
