5. How many moles of sodium are needed to react with sulfuric acid to prod sodium suffate according to the following (unbalanced) reaction: underline ( )Na+underline ( )H_(2)(SO_(4))arrow underline ( )Na_(2)(SO_(4))+underline ( )

To determine the number of moles of sodium (Na) needed to react with sulfuric acid (H₂SO₄) to produce sodium sulfate (Na₂SO₄), we first need to balance the chemical equation.The unbalanced reaction is: To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.1. Start with sodium (Na): - There are 2 sodium atoms in Na₂SO₄ on the product side. - Therefore, we need 2 sodium atoms on the reactant side.2. Balance sulfur (S): - There is 1 sulfur atom in H₂SO₄ on the reactant side. - There is 1 sulfur atom in Na₂SO₄ on the product side. - Sulfur is already balanced.3. Balance hydrogen (H): - There are 2 hydrogen atoms in H₂SO₄ on the reactant side. - There are 2 hydrogen atoms in 2 H₂O on the product side. - Hydrogen is already balanced.The balanced equation is: From the balanced equation, we see that 2 moles of sodium (Na) are required to react with 1 mole of sulfuric acid (H₂SO₄) to produce 1 mole of sodium sulfate (Na₂SO₄).Therefore, the number of moles of sodium needed is 2 moles.
