Answer 1

2Zn + O2 — 2ZnO – реакция соединения
ZnO + H2SO4 — ZnSO4 + H2O – реакция обмена
ZnSO4 + BaCl2 — ZnCl2 + BaSO4 – реакция обмена

C + O2 — CO2 – реакция соединения
CO2 + Na2O — Na2CO3 – реакция соединения
Na2CO3 + CaCl2 — CaCO3 + 2NaCl – реакция обмена

Answer 2

1) 2Zn + O2 -> 2ZnO (реакция соединения)
ZnO+H2SO4 -> ZnSO4 + H2O (реакция обмена)
ZnSO4 +BaCl2 -> BaSO4 + ZnCl2 ( реакция обмена)

2) C+O2 -> CO2 (реакция соединения)
2NaOH + CO2 -> Na2CO3 + H2O (реакция обмена)
Na2CO3 + CaCl2 -> CaCO3 + 2NaCl (реакция обмена)

Answer 3

Prerequisites

Before we can determine the type of reaction and provide a detailed explanation, let's break down the given chemical equation and identify the substances involved:

1. Zn -> ZnO 2. ZnO -> ZnSO4 3. ZnSO4 -> BaSO4 + C 4. C -> CO2 5. CO2 -> Na2CO3 6. Na2CO3 -> CaCO3

Reaction 1: Zn -> ZnO

The first reaction involves the transformation of zinc (Zn) into zinc oxide (ZnO). This is an example of a combination reaction, where two or more substances combine to form a single product. In this case, zinc combines with oxygen to form zinc oxide.

Reaction 2: ZnO -> ZnSO4

The second reaction shows the conversion of zinc oxide (ZnO) into zinc sulfate (ZnSO4). This is a single displacement reaction, where one element replaces another element in a compound. Here, zinc oxide reacts with sulfuric acid to produce zinc sulfate.

Reaction 3: ZnSO4 -> BaSO4 + C

The third reaction involves the decomposition of zinc sulfate (ZnSO4) into barium sulfate (BaSO4) and carbon (C). This is a decomposition reaction, where a compound breaks down into simpler substances. In this case, zinc sulfate decomposes into barium sulfate and carbon.

Reaction 4: C -> CO2

The fourth reaction represents the combustion of carbon (C) to produce carbon dioxide (CO2). This is an example of a combustion reaction, where a substance reacts with oxygen to produce carbon dioxide and water vapor.

Reaction 5: CO2 -> Na2CO3

The fifth reaction shows the conversion of carbon dioxide (CO2) into sodium carbonate (Na2CO3). This is a combination reaction, where carbon dioxide combines with sodium hydroxide to form sodium carbonate.

Reaction 6: Na2CO3 -> CaCO3

The final reaction involves the transformation of sodium carbonate (Na2CO3) into calcium carbonate (CaCO3). This is an example of a double displacement reaction, where two compounds exchange ions to form two new compounds. In this case, sodium carbonate reacts with calcium chloride to produce calcium carbonate and sodium chloride.

To summarize, the given chemical equation involves a combination reaction, single displacement reaction, decomposition reaction, combustion reaction, and double displacement reaction.
