The lattice energy for MgO is 3890 kJ/mol, as well as the second ionization energy (IE2) of MG is 1450.6 kJ/mol. Utilizing these data find out the second electron affinity for oxygen EA2(O).
Could someone solve this for me as well as show me how it is done step-by-step.

What is the pH of a solution prepared by mixing 100 mL of 0.020 M Ca(OH)2 with 50 mL of 0.100 M NaOH? assume that the volumes are additive.
Using A flow diagram, show the separation of a mixture containing p-bromoacetanilide, N-cyclopentyl-N-methyl-N-propylamine (N means the group is attached to the nitrogen of the amine) and m-nitrophenol.
is believed to follow the mechanism H2O2 + I- ? H2O + IO- fast H2O2 + IO- ? H2O + O2 + I- slow At 25oC, the first step is fast relative to the second step. What is the rate law predicted by this mechanism?
(a) What is the product. (b) Provide a mechanism showing the formation of the product at a. (c) Suggest a more feasible synthesis condition for the conversion.
This deprotonated species which bears a negative charge on the carbon atom is stabilized by resonance. -Please explain how it stabilizes, and show the other contributing resonance form and name this ion.
estimate the amount of carbon dioxide (in tonnes) that is consumed over a 6-month period by the forest, assuming trees are 50% glucose and 50% water. How much sunlight (in GJ) has the forest absorbed in that period?
A voltaic cell is constructed by immersing a strip of silver in a 1.0M AgNO3 solution and a strip of cadmiun metal in a 1.0M Cd(NO3)2 solution. The circuit is completed by a wire and a salt bridge in the usual way. Write the balanced half-reaction..
