A 0.4000 g sample that contained 96.4% Na2SO4 (142.04 g/mol) required 41.25 mL of barium chloride solution to reach the endpoint in a precipitation titration. What is the molarity of the BaCl2 solution
What mass of barium sulfate is produced when 100.0 mL of a 0.100 M solution of barium chloride is mixed with 100.0 mL of a 0.100 M solution of iron(III) sulfate.
A 500.0 g iron bar at 212 degrees C is placed in 2.0L of water at 24.0 degrees C. What will be the change in temperature of the water?
If a nonvolatile, yellow crystalline solid sample of 0.351 g is dissolved in benzene (C 6 H 6 ) of 15.8 g formed a solution. this solution freezes at the temperature of 4.77 degree celsius.
Draw any resonance form and state whether it is more or less stable than the original. ( if this is explained i will reward all points)
One thousand kg/h of an ethanol/methanol stream is to be separated in a distillation column. The feed has 40% ethanol and the distillate has 90% methanol. Eighty percent of the methanol is to be recovered as distillate. Determine the % methanol in ..
