Which has the larger hydration energy, AL+3 or Li+ (Both ions are about the same size)
a. Li+ because it has a smaller chargeb. Li+, because it has smaller atomic massc. Al+3 because it has a larger charged. Al=3 because it has a larger atomic masse. Al+3 but for some other reasonf. Li+ but for some other reason
Suppose sulfur dioxide reacts with oxygen at 25 degrees Celsius. 2SO2 (g) + O2 (g) ->
compute the enthalpy change, (Delta H), for this reaction per mole of A. suppose that the specific heat =[4.18J/(g*Degrees C) and density=1.00(g/mL)?
Use the dipole moments of and ( HCl= 1.08, Hf= 1.82) together with the percent ionic character of each bond ( HCl= 20% ionic, HF= 45% ionic) to estimate the bond length in each molecule.
Glycerol, C3H8O3, is a water-soluble liquid of density 1.2656 g/ml at 15oC. Calculate the molarity of a solution of glycerol made by dissolving 40.000 ml glycerol at 15oC in enough water to make 250.000 ml of solution.
When there are branches in either the acid or the alcohol, how do you name the ester formed from the reaction of these two? For example,
