Oxygen is not normally found in positive oxidation states, but when it is combined with fluorine in the compound oxygen difluoride, oxygen is in a +2 oxidation state. Oxygen difluoride is a strong oxidizing agent that oxidizes water to produce O2 and HF. OF2(g) + H2O(g) → 2 HF(g) + O2(g) The standard formation enthalpy of oxygen difluoride is 24.5 kJ/mol. Using this information and data from Appendix J, calculate the standard reaction enthalpy for the reaction of oxygen difluoride with water. Table 4.2 Selected Standard Formation Enthalpies, ΔfH°, at 25°C
A student is given a sample of a pink manganese (II) chloride hydrate. She weighs the sample in a dry, covered crucible and obtains a mass of 26.742g for the crucible, cover, and sample. Earlier she had found that the crucible and cover weighed 23.599g. She then heats the crucible to drive off the water of hydration, keeping the crucible at red heat for about 10 minutes with the cover slightly ajar. She then lets the crucible cool and finds it has a lower mass; the crucible, cover and contents then weigh 25.598g. In the process the sample was converted to off-white anhydrous MnCl2. a. What was the mass of the hydrate sample? _ghydrate b. What is the mass of the anhydrous MnCl2? _gMnCl2 c. How much water was driven off? _gH2O d. What is the percent by mass of water in the hydrate? water=massofwaterinsamplemassofhydrateinsample100 _massH2O e. How many grams of water would there be in 100.0g hydrate? How many moles? _gH2O; _molesH2O f. How many grams of MnCl2 are there in 100.0g hydrate? How many moles? What percentage of the hydrate is MnCl2? Convert the mass of MnCl2 to moles. The molar mass of MnCl2 is 125.85g/mol. _gMnCl2; _molesMnCl2 g. How many moles of water are present per mole MnCl2? _ h. What is the formula of the hydrate? _

You have been tasked with determining the wastewater solids generated by a community. To determine solids, you collect two effluent samples of 100 mL each. The first sample was placed, unfiltered, in a crucible and dried at 105 ̊C overnight. The weight of the dried sample and crucible was 5.6112 g, while the weight of the crucible was 5.6000 g. The second sample was filtered. The filter and drying dish were dried overnight at 105 ̊C after which they weighed 2.1085 g. The filter and drying dish were then placed in a muffle furnace at 550 ̊C for 30 mins, after which they weighed 2.103 g. The drying dish weighs 1.6000 g and the filter weighs 0.5 g. a) Determine the concentration of TS, TSS, VSS, FSS and TDS in mg/L: b) Does TSS concentration meet the federal effluent regulations? If not, what removal techniques would you recommend and what minimum percent must be removed prior to discharge?
