A tanker truck carrying 2.01×10^3kg of concentrated sulfuric acid solution tips over and spills its load. The sulfuric acid solution is 95.0% H2SO4 by mass and has a density of 1.84g/mL Sodium carbonate (Na2CO3) is used to neutralize the sulfuric acid spill. How many kilograms of sodium carbonate must be added to neutralize 2.01×10^3kg of sulfuric acid solution?.
The titration requires 34.11 mL of base to neutralize 15.00 mL of the acid. What is the Molarity if acid in the vinegar?
Zinc sulfide reacts with nitric acid to give zinc sulfate and nitric oxide. Calculate the mass of zinc required to react with 110 mL of 0.15 M nitric acid.
Solutions of strontium hydroxide, silver nitrate, hydrogen phosphate, potassium nitrate, and copper (II) sulphate are prepared and placed in separate containers. Consider the reaction of the pairs of these compounds.
What mass of NaHCO3 must be added to 1.00 L of 0.10 M Na2CO3 to make a buffer solution whose pH=9.85? pKa2(H2CO3)=10.33
How Many moles of NaOH are needed to neutralize the acid? D) Calculate the volume of NaOH solution required to react completely with the acid.
A solution is 0.10 M AgNO3 and 0.10 M Ba(NO3)2. If solid Na2SO4 is added to the solution, what is [Ba2+] when Ag2SO4 begins to precipitate? (Ksp BaSO4 = 1.1 x 10-10; Ag2SO4 = 1.1 x 10-5)
A student was preparing to recrystallize a solid using mixed-solvent recrystallization. He planned to dissolve the sample in boiling methanol, and then add hot pentane to induce crystallization
One of the reasons that back titration is preferred to direct titration is because of the limited solubility of carbonates in water. Why does this make direct titration difficult and why does back titration tend ot circumvent this difficulty
calculate the number of grams of iron and the number of grams of carbon dioxide formed
Now consider a sample that consists of four spheres, each with a different mass: blue mass is 4.00 g, red mass is 3.75 g, green mass is 3.00 g, and yellow mass is 1.25 g. Calculate the average mass of a sphere in this sample.
Nickel nitrate and potassium carbonate react to form nickel carbonate and potassium nitrate. How many milliliters of 0.55M Ni(NO3)¬2 are needed to react with 85 mL of 0.25M K2CO3? First, write a balanced equation.
