Matching the Left and Right Parts of Chemical Reactions:

To match the left and right parts of the given chemical reactions, we need to identify the correct products for each reactant. Let's go through each reaction and find the corresponding products:

1. MgCO3 → 2 AgNO3 - The left part of the reaction represents magnesium carbonate (MgCO3). - The right part of the reaction represents silver nitrate (AgNO3). - Therefore, the correct match is: a) magnesium carbonate → silver nitrate.

2. NaCl → 3 Pb(NO3)2 - The left part of the reaction represents sodium chloride (NaCl). - The right part of the reaction represents lead nitrate (Pb(NO3)2). - Therefore, the correct match is: b) sodium chloride → lead nitrate.

3. Mg → 4 FeS - The left part of the reaction represents magnesium (Mg). - The right part of the reaction represents iron sulfide (FeS). - Therefore, the correct match is: d) magnesium → iron sulfide.

4. H2SO4 → a) AgCl - The left part of the reaction represents sulfuric acid (H2SO4). - The right part of the reaction represents silver chloride (AgCl). - Therefore, the correct match is: a) sulfuric acid → silver chloride.

5. NaNO3 → b) Mg(NO3)2 - The left part of the reaction represents sodium nitrate (NaNO3). - The right part of the reaction represents magnesium nitrate (Mg(NO3)2). - Therefore, the correct match is: b) sodium nitrate → magnesium nitrate.

6. Pb → 3 AgNO3 - The left part of the reaction represents lead (Pb). - The right part of the reaction represents silver nitrate (AgNO3). - Therefore, the correct match is: c) lead → silver nitrate.

7. FeS → d) MgO - The left part of the reaction represents iron sulfide (FeS). - The right part of the reaction represents magnesium oxide (MgO). - Therefore, the correct match is: d) iron sulfide → magnesium oxide.

8. CO2 → c) PbS - The left part of the reaction represents carbon dioxide (CO2). - The right part of the reaction represents lead sulfide (PbS). - Therefore, the correct match is: c) carbon dioxide → lead sulfide.

To summarize the matches:

1. MgCO3 → 2 AgNO3: a) magnesium carbonate → silver nitrate 2. NaCl → 3 Pb(NO3)2: b) sodium chloride → lead nitrate 3. Mg → 4 FeS: d) magnesium → iron sulfide 4. H2SO4 → a) AgCl: a) sulfuric acid → silver chloride 5. NaNO3 → b) Mg(NO3)2: b) sodium nitrate → magnesium nitrate 6. Pb → 3 AgNO3: c) lead → silver nitrate 7. FeS → d) MgO: d) iron sulfide → magnesium oxide 8. CO2 → c) PbS: c) carbon dioxide → lead sulfide
