Thus, in the crystal structures of NH 2 (CH 3) 2Al 1−x Cr x (SO 4) 2 × 6H 2 O with x = 02 and 0065 octahedra are occupied by statistical mixtures of magnetic Cr −The Cr−MSUx synthesized with Si/Cr = , aging at 25 °C for 22 h, and templating by fatty alcohol polyoxyethylene ether gave the best activities, resulting in 580% ethane conversion and 921% ethylene selectivity The Cr species in Cr−MSUx are more efficient in activating and converting ethane molecules than are conventional catalysts †Solution By definition S is the set of x satisfying 1 < x ≤ 5 Hence 1 is a lower bound for S Suppose that 1 is not the GLB of S Then there is an ǫ > 0 such that 1 ǫ is also a lower bound for S To contradict this, we exhibit x ∈ S such that 1 < x < 1ǫ Since 0 < ǫ 2 < ǫ we see that x = 1 ǫ 2 satisfies 1 < x < 1ǫ Characterization Of Chromium Species And Distribution During Cr Vi Removal By Biochar Using Confocal Micro X Ray Fluorescence Redox Mapping And X Ray Absorption Spectro
