Answer 1

Ответ:

Объяснение:

1) Na2O + H2O = 2NaOH (соединение)

2CO + O2 = 2CO2 (соединение)

NH4NO3 = N2O + 2H2O (разложение)

Mg + CuO = MgO + Cu (замещение)

BaCl2 + K2CO3 = BaCO3↓ + 2KCl (обмен)

2) 2Ag2O =4Ag + O2↑ (разложение)

4Al+ 3O2 = 2Al2O3 (соединение)

2HCl + Zn = ZnCl2 + H2↑ (замещение)

3) 2Al + 3Br2 = 2AlBr3 (соединение)

CaCO3 = CaO + CO2 (разложение)

2N2 + 3O2 =2 N2O3 (соединение)

4) Fe + 2HCl = FeCl2 + H2↑ (замещение)

2Al + 3Cl2 = 2AlCl3 (соединение)

Zn + 2HCl = ZnCl2 + H2↑ (замещение)

#### Types of Chemical Reactions Chemical reactions can be classified into several types based on the changes that occur during the reaction. Some common types of chemical reactions include: 1. **Combination Reaction (Synthesis Reaction):** In a combination reaction, two or more substances combine to form a single product. The general form of a combination reaction is: A + B → AB For example: - Na2O + H2O → 2NaOH [[1]] - CO + O2 → CO2 [[2]] 2. **Decomposition Reaction:** In a decomposition reaction, a single compound breaks down into two or more simpler substances. The general form of a decomposition reaction is: AB → A + B For example: - NH4NO3 → N2O + H2O [[3]] 3. **Displacement Reaction (Single Replacement Reaction):** In a displacement reaction, an element reacts with a compound, displacing another element from it. The general form of a displacement reaction is: A + BC → AC + B For example: - Mg + CuO → MgO + Cu [[4]] 4. **Double Displacement Reaction (Metathesis Reaction):** In a double displacement reaction, the positive and negative ions of two compounds exchange places to form new compounds. The general form of a double displacement reaction is: AB + CD → AD + CB For example: - BaCl2 + K2CO3 → BaCO3 + 2KCl [[5]] #### Balancing Chemical Equations 1. Na2O + H2O → 2NaOH (Combination Reaction) 2. CO + O2 → CO2 (Combination Reaction) 3. NH4NO3 → N2O + H2O (Decomposition Reaction) 4. Mg + CuO → MgO + Cu (Displacement Reaction) 5. BaCl2 + K2CO3 → BaCO3 + 2KCl (Double Displacement Reaction) #### Writing Equations and Identifying Reaction Types 1. Aluminum + Bromine (diatomic molecule) → Aluminum Bromide (Synthesis Reaction) 2. Calcium Carbonate → Calcium Oxide + Carbon Dioxide (Decomposition Reaction) 3. Nitrogen (diatomic molecule) + Oxygen → Nitrogen Oxide (III) (Combination Reaction) #### Completing Equations and Identifying Reaction Types 1. Ag2O → 2Ag + O2 (Decomposition Reaction) 2. 4Al + 3O2 → 2Al2O3 (Combination Reaction) 3. 2HCl + Zn → ZnCl2 + H2 (Displacement Reaction) Please note that the missing reactants/products in the equations were not provided in the question.
