10.00ml of the final acid solution is reacted with excess barium chloride to produce a precipitate of barium sulfate (FW = 233.4 g/mol). (Final acid solution from previous question was 0.06Molarity). The dry solid weighs 0.397g. Use this mass and the dilution volumes to calculate the ACTUAL molarity of the sulfuric acid in the INITIAL solution.
What pressure would have to be applied to a 28.0mL sample of gas at 25°C and 1.00atm to compress its volume to 10.0mL at constant temperature?
what is the energy of an X ray with a wavelength of 3.52×10-9m and a microwave with a wavelenght of 6.63×10-2m?
An experiment requires 43.0 of ethylene glycol, a liquid whose density is 1.114 . Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
draw and label structures cis and trans isomers of 3,4 -dibromo-3-hexene, 3) structure of terpin hydrate. Is it more water soluable or less than the starting material?
if 100 mL of 0.100 M NaCl is added to 100 mL of .01 M NaCl, what is the concentration of Na ions in the final solution?"
If you mix 50mL of 0.34M HCN with 100mL of 0.17M KOH what is the pH of the resulting solution. (Ka=4.0 x 10^-10)
how many grams of iron will react with water to form iron (III)oxide and 85 liters of hydrogen gas at 19 degrees celsius & 525 torr?
The synthesis of Amyl acetate by alcohol and anhydride, there are some chemicals be provided: Potassium carbonate, Calcium carbonate, Sodium sulfate
Aqueous sulfuric acid will react with solid sodium hydroxide to produce aqueous sodium hydrogen sulfate and liquid water . Suppose 3.92 g of sulfuric acid is mixed with 2.22 g of sodium hydroxide.
So he concluded that entropy of ice must be greater than that the entropy of water liquid at 0 C. do you agree with his conclusion?
Calculate the energy produced when 15 grams of liquid methanol (CH3OH) is completely burnt in air to produce carbon dioxide gas
Concrete used in road construction is reinforced using steel bars in a grid, known collectively as "rebar." After many years, rebar will begin to corrode, and the concrete will weaken.
