Turtless are nerest to

The ionic radii of alkaline earth metals are smaller than those of the nerest alkali metals. Why ?

For the octahedral complex of Fe^(+) in SCN^(-) (thiocyanato-S) and in CN^(-) ligand environments, the difference between the spin - only magnetic moments in Bohr magneton (when approximated to the nerest integer) is [At. No . of Fe = 26]

Metal sphere, each of radius 2 cm, are packed into a rectangular box of internal dimension 16 cm xx 8 cm xx 8 cm . When 16 spheres are packed the box is filled with presrvative liquied .Find the volume of this liquid. Give your answer to the nerest interger. [ use pi = 3.14 ].

For the reaction aA+bBrarrcC+dD , the plot of log k vs 1/T is given below, The temperature at which the rate constant of the reaction is 10^(-4) s^(-1) is _____K. (Rouded -off the nerest integer) [Given : The rate constant of the reaction is 10^(-5) s^(-1) at 500 K.]
