You have the following chemicals at your disposal: Cu (s), Fe (s), H₂ (g), Pt (s), 1 M CuSO₄, 1 M Fe(NO₃)₂, 1 M Cr₂(SO₄)₃, 1 M HCl, 1 M LiI, and H₂O What is the highest Standard Cell Potential (E°cell) obtainable with these materials?

Acetic acid, hc2h3o2, dissolves and completely dissociates in water and a solvation sphere of water molecules forms around the ions. this solute-solvent interaction

Compare and contrast physical changes with chemical changes.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
