Suppose that you started with 5ml of 100ppm Cu2+ solution and added it to 0.1g of soil. After mixing, you filter it and find that the concentration of the filtered solution is 5ppm Cu2+. From the above scenario, calculate the mass of Cu2+ bound to the soil. Calculate the K(dis).
Aluminum will act as the stronger reducing agent and iron will act as the stronger oxidant. In the spontaneous reaction, the oxidation number of iron will increase.
The heat of reaction for the combustion of cyclohexane, C6H12, is 936.8 kcal/mol. What is the heat of combustion for cyclohexane in kcal/gram?
The generalized van der Waals chemical potential of a pure solvent and a dilute solute in a solvent
Assume the total heat capacity of the air C air=30 J/K. Describe what's the likely ice will ne after the system reaches equilibrium. b) Estimate theliekly final temperature after reaching equilibrium
Investigators have reported experimental observation of the He2 ‘complex' (i.e., a very weakly bonded molecule). The fact that the observation required temperatures in the neighborhood of 1 mK is consistant with computational studies that hcDe for..
arrange the following alkenes in order of increasing heat of hydrogenation (That is, heat released when the compound is hydrogenated). 1 = lowest heat,...................5=highest heat
Consider all the valence electron pairs of the central atom-both those that are shared in covalent bonds, called bonding pairs, and those that are unshared, called non-bonding pairs or unshared pairs.
