A researcher creates a new manganese sulfide semiconductor, but does not know the oxidation state of the manganese. She can get the oxidation state from the stoichiometry of of the compound, but this is also unknown. She reacts 0.181 grams of her semiconductor with excess nitric acid which oxidizes all of the sulfur to sulfate, SO2−4(aq), and manganese to permanganate, MnO−4(aq). She then dilutes the acid digestion to 150 mL and uses Inductively-Coupled Plasma-Atomic Emission Spectroscopy to determine that the concentration of permanganate is 0.01388 μM and the concentration of sulfate is 0.01388 μM. What is the empirical formula of the original sample?

In meteorology, a  cloud  is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. nephology is the science of  clouds, which is undertaken in the  cloud  physics branch of meteorology.cirrus clouds  usually describe clouds high in the atmosphere that can include wispy clouds, typically with ice crystals. variations include cirrus, cirrocumulus and cirrostratus as defined by the cloud's position in the atmosphere.layered stratus clouds  have both flat tops and bases, and can appear as if they take up the whole sky, stretching from horizon to horizon. other combinations and variations include stratus, stratocumulus, nimbostratus and altostratus.cumulus clouds  often pile up in multiple layers of the atmosphere, representing clouds that develop vertically. cumulus clouds often look like pillars with anvil-type tops or columns of clouds stacked vertically. variations include cumulus, cumulus-congestus, cumulonimbus and altocumulus.
