d. 2 NaCl + Br₂-2 NaBr2 + Cl₂
e. C3H8 +50₂ - 3 CO₂ + 4H₂O

Answer 1

The types of reactions for the given equations can be classified as follows: a. Na + Cl → NaCl is a synthesis reaction; b. 2 H₂O → H₂ + O₂ is a decomposition reaction; e. C3H8 + 5O₂ - 3 CO₂ + 4H₂O is a combustion reaction; 4.3: Zn + Fe(NO3)2 illustrates a single replacement reaction; and b. NaCl + AgNO3 → AgCl + NaNO3 is a double displacement reaction.

Step-by-step explanation:

Types of Chemical Reactions

To match the given equations to the type of reaction, let's consider each one:

• 1. Synthesis - This is a type of reaction where two or more reactants combine to form a single product. An example is equation a. Na + Cl → NaCl, where sodium and chlorine combine to form sodium chloride.
• 2. Decomposition - This reaction involves a single compound breaking down into two or more simpler substances. An example is equation b. 2 H₂O → H₂ + O₂, which represents the decomposition of hydrogen peroxide into water and oxygen.
• 3. Combustion - A combustion reaction involves a hydrocarbon (like propane) reacting with oxygen to produce carbon dioxide and water. The equation e. C3H8 + 5O₂ - 3 CO₂ + 4H₂O is an example of a combustion reaction.
• 4. Single replacement - In this reaction, an element replaces another element in a compound. For example, in the reaction 4.3: Zn + Fe(NO3)2 → ?, zinc would replace the iron in the compound to form zinc nitrate and elemental iron.
• 5. Double displacement - This reaction involves the exchange of ions between two compounds to form two new compounds. The equation b. NaCl + AgNO3 → AgCl + NaNO3 shows a double displacement reaction where sodium trades places with silver.
