Would the following reactions happen? Al+Mg(C_(2)H_(3)O_(2))_(2)arrow square Zn+MgCO_(3)arrow square Cu+AgNO_(3)arrow square Mg+HClarrow square

Let's analyze each reaction step by step:<br /><br />1. **Reaction: $Al + Mg(C_{2}H_{3}O_{2})_{2} \rightarrow \square $**<br /><br /> Aluminum (Al) is less reactive than magnesium (Mg) in the activity series of metals. Therefore, aluminum cannot displace magnesium from magnesium acetate ($Mg(C_{2}H_{3}O_{2})_{2}$). Hence, this reaction will not occur.<br /><br /> **Answer: No reaction**<br /><br />2. **Reaction: $Zn + MgCO_{3} \rightarrow \square $**<br /><br /> Zinc (Zn) is more reactive than magnesium (Mg) in the activity series of metals. Therefore, zinc can displace magnesium from magnesium carbonate (MgCO₃). The reaction would be:<br /><br /> $Zn + MgCO_{3} \rightarrow ZnCO_{3} + Mg$<br /><br /> **Answer: $ZnCO_{3} + Mg$**<br /><br />3. **Reaction: $Cu + AgNO_{3} \rightarrow \square $**<br /><br /> Copper (Cu) is less reactive than silver (Ag) in the activity series of metals. Therefore, copper cannot displace silver from silver nitrate (AgNO₃). Hence, this reaction will not occur.<br /><br /> **Answer: No reaction**<br /><br />4. **Reaction: $Mg + HCl \rightarrow \square $**<br /><br /> Magnesium (Mg) is more reactive than hydrogen (H) in the activity series of metals. Therefore, magnesium can displace hydrogen from hydrochloric acid (HCl). The reaction would be:<br /><br /> $Mg + 2HCl \rightarrow MgCl_{2} + H_{2}$<br /><br /> **Answer: $MgCl_{2} + H_{2}$**<br /><br />In summary:<br />1. $Al + Mg(C_{2}H_{3}O_{2})_{2} \rightarrow$ No reaction<br />2. $Zn + MgCO_{3} \rightarrow ZnCO_{3} + Mg$<br />3. $Cu + AgNO_{3} \rightarrow$ No reaction<br />4. $Mg + HCl \rightarrow MgCl_{2} + H_{2}$
