Write a balanced equation with phase changes for an electrochemical cell that has a copper cathode immersed in a solution of cu+2 ions and a lead anode immersed in a solution of Pb+2 ions
She pours a 50.0 mL sample of water at 345 K into the calorimeter containing a 50.0 mL sample of water at 298 K. She carefully records the final temperature of the water as 317 K. What is the value of Ccal for the calorimeter?
Example: Determine the solubility of calcium fluoride at 25C. And Be sure to note the difference between Solubility and Solubility Product Constant ! What could we do to change the system and produce a precipitate?
Could someone please explain why synthesized soap and detergent have different reactions when they are mixed with calcium chloride
Calculate the standard potential for this reaction. Normally, X is Fe. Here it is some unknown metal, allowing for somewhat random values for ΔGo.
The half-life for the radioactive decay of [U]-238 is 4.5 billion years and is independent of initial concentration.
Calculate ΔHo fusion and ΔSo fusion for the substance If the pressure is increased to 120 bar, the melting temperature increases to 375.88 K. ?
Determine the molarity of the NaOH(sodium hydroxide) solution. In an acid-base titration, 22.13 mL of a sodium hydroxide solution are required to neutralize 24.65 mL of the potassium hydrogen phthalate solution?
If 4.50 moles of ethane, C2H6 undergo combustion,according to the unbalanced equation C2H6+O2--> CO2+H2O, how many moles of oxygen are required?
A 280- mL flask contains pure helium at a pressure of 757 torr. A second flask with a volume of 465 mL contains pure argon at a pressure of 715 torr.
A 28.5 g sample of an unknown metal is heated to 95.0C and then dropped into 58.0 g of water in a coffee-cup calorimeter. The temperature of the water rises from 23.5 C to 27.1C.
