Which statement is true in regards to a half reaction in which reduction occurs? A)An electron is a product. B) An electron is a reactant. C) An electron is both a reactant and a product. D) Oxidation also occurs. E) None of the above
Draw and discuss the mechanism of the Diels-Alder reaction (with arrows to show the electron movements). Draw the orientation of the reacting p-orbitals and indicate how they overlap to form product.
Can anyone help me with the reaction sequence AND stepwise mechanism for the mono-nitration of phenyl methyl ketone
which compartment (A or B) will increase in volume for each of the following pairs of solutions separated by a semipermiable membranes: a) A.20%(m/v) starch B.10%(m/v) starch. b) A.10%(m/v) albumin B.2%(m/v) albumin. c) A. .5%(m/v) sucrose B. 5%(m..
The molar heat cacpacity of silver is 25.35 J/ mol C. How much energy would it take to raise the temperature of 11.1g of silver by 14.2 C? B) Find the specific heat of silver?
Comment on whether these are made of the same materials or not, and explain your response. The density is different in each, so they are made of different materials.
Calculate deltaS, deltaStotal, and deltaSsurroundings when the volume of 84.0g of CO initially at 298K and 1.00bar increases by a factor of four in (a) an adiabatic reversible expansion, (b) an expansion againt Pexternal=0, and (c) an isothermal r..
