From the following information
`{:(A^(-)(g)rarrA^(+2)(g)+3e^(-),DeltaH_(1) = 1400 kJ//"mole"),(A(g)rarrA^(+2)(aq)+2e^(-),DeltaH_(2) = 700 kJ//"mole"),(DeltaH_(EG)[A^(+)(g)] =- 350 kJ//mol,),((IE_(1)+IE_(2))for A(g) = 950kJ//mol,):}` Find
(a) `IE_(1)` of A (b) `IE_(2)` of A (c) `DeltaH_(EG)` of A (d) `DeltaH_(HE)` of A^(2+)(g)`
