Which of the following relations are functions? Give reasons. In case of a function, find its domain and range. (i) f={(1 ,3),(1,5),(2,3),(2,5)} (ii) g={(2,1),(5,1),(8,1),(11,1)} (iii) h={(2,1),(4,2),(6,3),(8,4),(10,5),(12,6)}

Which of the following relations are functions? Give reasons. If it is a function, determine its domain and range: (i) {(2,1), (3,1),(4,2)} (ii) {(2,2),(2,4),(3,3),(4,4)} (iii) {(2,1),(5,1),(8,1),(11,2),(14,2),(17,2)} (iv) {(1,2),(2,3),(3,4),(4,5),(5,6),(6,7)} (v){(2,1),(4,2),(6,3),(8,4),(10,5)} (vi) {(1,2),(2,3),(3,4),(3,5),(3,7),(4,8)}

Is the following relation a function ? Justify your answer: (i) R_(1) = {(2,3), ((1)/(2), 0), (2,7), (-4,6)} (ii) R_(2) = {(x,|x|): x" is a real number" )

Gibbs-Helmoholtz equation relates the free energy change to the enthalpy and entropy changes of the process as (DeltaG)_(PT) = DeltaH - T DeltaS The magnitude of DeltaH does not change much with the change in temperature but the enrgy factor T DeltaS changes appreciably. Thus, spontaneity of a process depends very much on temperature. The dissolution of CaCI_(2).6H_(2)O in a large volume of water is endothermic to the extent of 3.5 kcal mol^(-1) . For the reaction. CaCI_(2)(s) +6H_(2)O(l) rarrCaCI_(2).6H_(2)O(s) DeltaH is -23.2 kcal . The heat of solution of anhydrous CaCI_(2) in large quantity of water will be

Examine each of the following relations given below and state in each case, giving reasons whether it is a function or not ? (i) R={(4,1),(5,1),(6,7)} (ii) R={(2,3),(2,5),(3,3),(6,6)} (iii) R={(1,2),(2,3),(3,4),(4,5),(5,6),(6,7)} (iv) R={(1,1),(2,1),(3,1),(4,1),(5,1)}
