Ответ:

WO3 + 3H2 → W + 3H2O Замещение

оксид вольфрама(VI) + молекула водорода→вольфрам + вода

BaCO3 → BaO + CO2 Разложение

термического разложения карбоната бария→оксид бария+оксид углерода(IV)

AlCl3 + 3NaOH → Al(OH)3 + 3NaCl Реакция обмена

хлорид алюминия+гидроксид натрия→гидроксид алюминия + хлорид натрия

2Fe(OH)3 → Fe2O3 + 3H2O Разложение

гидроксид железа(III) → гематит + вода

Zn + H2SO4 → ZnSO4(разб) + H2 Замещение

цинк + серная кислота → сульфат цинка + молекула водорода

4Zn + 5H2SO4(конц) → 4ZnSO4 + H2S + 4H2O

цинк + серная кислота → сульфат цинка + сероводород + вода

2Fe + 3Cl2 → 2FeCl3 Синтез

железо + дихлор → хлорид железа(III)

H3PO4 + 2KOH → K2HPO4 + 2H2O Двойное разложение (Кислотное)

ортофосфорная кислота+гидроксид калия→гидроортофосфат калия + вода

2Al + 3CuSO4 → Al2(SO4)3 + 3Cu Замещение

алюминий + сульфат меди(II) → сульфат алюминия + медь

Books and friends should be few but good," says an English proverb.
"Except1 a living man there is nothing more wonderful than a book! It teaches us and opens its heart to us as a brother," wrote Charles Kingsley, an English writer of the 19th century. The book is certainly a friend and a teacher. We learn many things by reading books. Books teach people to live. After reading some books it is easy to understand what should be done and what must not be done. There are books which help pupils with their lessons.
In general, books can be divided into two main groups: fiction and non-fiction. Fiction books contain made-up stories, non-fiction books are books that give facts.
In ancient times books were written by hand and few copies were made. Sometimes several men were needed to copy a book as the work was slow. For many years the number of books in the world was very small. Only a few people had copies of them to read and study.
The invention of printing changed a lot in history. Printing played a very important role in the development of culture, science and literature.
Today, there are many thousands of public libraries in Ukraine. Librarians are always ready to help people to find a book on any subject if they do not know the title of the book they want. Those who know how to use the catalogue can find a book and needn't consult the librarian.
