D. Double displacement reaction

Answer 1

The balanced chemical equation for the reaction between magnesium sulfate and sodium hydroxide is MgSO4 + 2NaOH → Na2SO4 + Mg(OH)2. This is a double displacement reaction. The reactants for the reaction between iron(II) chloride and sodium carbonate are iron(II) chloride and sodium carbonate, and the products are iron(II) carbonate and sodium chloride.

Step-by-step explanation:

a. The skeletal equation for the reaction is:

MgSO4 + 2NaOH → Na2SO4 + Mg(OH)2

To balance the equation, there needs to be 2NaOH on the left side of the equation. The balanced chemical equation is:

MgSO4 + 2NaOH → Na2SO4 + Mg(OH)2

b. The reaction is a double displacement reaction because the positive ions in the reactants switch places to form new compounds. Magnesium sulfate and sodium hydroxide react to produce sodium sulfate and magnesium hydroxide.

c. The reactants for the second reaction are Iron(II) chloride and sodium carbonate.

d. The products for the second reaction are Iron(II) carbonate and sodium chloride.

e. The second reaction is a double displacement reaction because the positive ions in the reactants switch places to form new compounds.
