Which of the following aqueous solutions has the highest boiling point? (Hint: think about what affects the boiling point of solutions?) A) 0.100 M sulfuric acid C) 0.100 M magnesium sulfate B) 0.100 M copper (II) sulfate D) 0.100 M potassium sulfate Which of the following carboxylic acids is the least soluble in water? (Like so many of these problems, I don't expect you to just know the answer right away, but I expect you to be able to reason it out by thinking about what factors determine solubility). A) H,NCH,COOH B) HOOCCH,CH,COOH C) CH;CH,CH,CH,CH,COOH D) FCH,COOH

I need help solving the following problem. How many grams of iodine potassium iodide would it take to obtain a 100 mL solution of 0.300 M IKI? Note: Recall that “IKI” is an abbreviation for iodine potassium iodide. The chemical formula is I3K and the molecular mass is 419.8 g/mole.

Please calculate the amount of solid sodium hydroxide needed to make 200mL of a 0.2 M soulution. **Please give answer to nearest .001 g** Also, if 10 mL of the solution made in the last question is used to make another 125mL solution of NaOH, what is the new concentration? If you dont mind, please show the each step to solve the problem, that would be great!  Have a absolutely amazing day whoever you are that does these questions for students like me. :)

Determine if the ionic solids below are more soluble in acidic or basic solutions compared to neutral water: NH4Cl and CaCO3. Write the chemical reaction which shows them reacting in an acid or base solution.

A solution prepared by dissolving 682 mg of a sugar (a molecular compound and a nonelectrolyte) in 1.00g of water froze at -372°C. What is the molar mass of this sugar? The value of K is 1.86°C/m. g/mol

A.) What is the pOH of an aqueous solution of 0.364 M nitric acid? B.) If 20.1 grams of an aqueous solution of aluminum nitrate, Al(NO3)3, contains 2.34 grams of aluminum nitrate, what is the percentage by mass of aluminum nitrate in the solution? C.) A sample of methane gas at a pressure of 0.638 atm and a temperature of 21.8 °C, occupies a volume of 11.1 liters. If the gas is compressed at constant temperature to a volume of 2.91 liters, the pressure of the gas sample will be__________  atm. ( fill in the blank)
