Answer:
46g of sodium acetate.
Explanation:
The data is: <em>Precipitation from a supersaturated sodium acetate solution. The solution on the left was formed by dissolving 156g of the salt in 100 mL of water at 100°C and then slowly cooling it to 20°C. Because the solubility of sodium acetate in water at 20°C is 46g per 100mL of water, the solution is supersaturated. Addition of a sodium acetate crystal causes the excess solute to crystallize from solution.</em>
The third solution is the result of the equilibrium in the solution at 20°C. As the maximum quantity that water can dissolve of sodium acetate at this temperature is 46g per 100mL and the solution has 100mL <em>there are 46g of sodium acetate in solution. </em>The other sodium acetate precipitate because of decreasing of temperature.

Answer:
The reaction products is in the attached file
Explanation:
The nitro group is characterized by being a very strong inhibitor. Nitrobenzene nitration is checked at a reaction rate that is 10 times lower than that of benzene. The nitro group is characterized by being a goal counselor. The chemical reaction of nitrobenzene nitration with nitric and sulfuric acids, 93% of the substitution is verified in the target position.
The answer should be 0.5 because 6/12 is 0.5. It gives u the key equation
S + O₂ = SO₂
1 mole S ------------ 1 mole SO₂
? mole S ----------- 15.0 mole SO₂
S = 15.0 * 1 / 1
= 15 moles of S
