Exposure to arsenic can result to subacute to severe toxicity and can sometimes be lethal and cause death. One source of arsenic is from agricultural runoffs. The concentration of arsenic in an agricultural wastewater is determined gravimetrically. A 25.0000 g sample of wastewater was precipitated as MGNH,AsO, and isolated as Mg,As,O7. Determine the %w/w_ of As,O, in the sample if it yields 1.5610 of Mg,As,O7.

Stoichiomestry: Write the chemical reaction for the IBX oxidation of Borneol. Using that, determine the limiting and excess reactant of the process. Lastly, compute for the theoretical. m of IBX = 0.5g m of Borneol = 0.2g V of DMSO = 4.0L
Chlorodifluoromethane (CHF2Cl) was widely used in the compression/cooling circuits of refrigeration or air-conditioning systems. Since the discovery that such compounds (HCFCs and CFC's) released into the atmosphere were a major cause of depletion of stratospheric ozone, newer refrigeration systems make use of certain hydrofluorocarbons (HFCs), which are degraded in the lower atmosphere, instead. Often, mixtures of such compounds are used. Suppose a sample of refrigerant gas consisting of a simple mixture of the gases pentafluoroethane (C2HF5) and difluorormethane (CH2F2) has a density of 3.06 g/L at 14 °C and 0.974 atm. Calculate the average molecular mass for this sample

The reaction of solid calcium fluoride and sulfuric acid produces calcium sulfate solids and gaseous HF. The gas product is dissolved in water to form hydrofluoric acid. Fluorite ore, a source of calcium fluoride, contains 95%wt CaF2 and 5%wt SiO2. In a certain process, the ore is reacted with 93%wt aqueous sulfuric acid, supplied 15% in excess. From this, 95% of the ore dissolves in the acid. Some of the HF formed reacts with the dissolved silica in the reaction: HF reacts with SiO2 to produce H2SiF6 and liquid water. If 60%wt of hydrofluoric acid was formed when hydrogen fluoride (which exits the reactor) is dissolved in water, determine the amount of ore needed to produce one metric ton of acid. Report your answers to one decimal place only.
