- Write the balanced neutralization reaction that occurs between H2SO4H2SO4 and KOHKOH in aqueous solution. Phases are optional. Suppose 0.950 L0.950 L of 0.400 M H2SO40.400 M H2SO4 is mixed with 0.900 L0.900 L of 0.300 M KOH0.300 M KOH. What concentration of sulfuric acid remains after neutralization?2complete and balance the ff. equationsSodium bicarbonate (baking soda), NaHCO3, can be purified by dissolving it in hot water (60 C), filtering to remove insoluble impurities, cooling to 0 C to precipitate solid NaHCO3, and then filtering to remove the solid, leaving soluble impurities in solution. Any NaHCO3 that remains in solution is not recovered. The solubility of NaHCO3 in hot water of 60 C is 164 g/L. Its solubility in cold water of 0 C is 69 g/L. What is the percent yield of NaHCO3 when ills purified by this method?
- Federal regulations set an upper limit of 50 parts per million(ppm) of NH3 in the air in a work environment [that is, 50molecules of NH31g2 for every million molecules in the air].Air from a manufacturing operation was drawn through asolution containing 1.00 * 102 mL of 0.0105 M HCl. TheNH3 reacts with HCl according to: NH3(aq) + HCl(aq)-------->NH4Cl(aq) After drawing air through the acid solution for 10.0 min at arate of 10.0 L/min, the acid was titrated. The remaining acidneeded 13.1 mL of 0.0588 M NaOH to reach the equivalencepoint. (a) How many grams of NH3 were drawn into theacid solution? (b) How many ppm of NH3 were in the air?(Air has a density of 1.20 g/L and an average molar mass of29.0 g/mol under the conditions of the experiment.) (c) Isthis manufacturer in compliance with regulations?25 mL of a bleach (NaOCl) sample is diluted to 500 mL. An excessive amount of KI is added to the 20 mL solution taken from here and the I2 released is titrated with 35.5 mL of 0.0409 M NaS2O3. Accordingly, calculate the weight percent by volume of NaOCl in the sample. (Ma(NaOC:74,4 g/mol)Please don,t provise handwrittensolution ....
- The concentration of CO in air is determined by passing a known volume of air through a tube that contains I2O5, forming CO2and I2. The I2 is removed from the tube by distilling it into a solution that contains an excess of KI, producing I3-. The I3-is titrated with a standard solution of Na2S2O3. In a typical analysis a 4.79-L sample of air is sampled as described here, requiring 7.17 mL of 0.00329 M Na2S2O3 to reach the end point. If the air has a density of 1.23 × 10–3 g/mL, determine the parts per million CO in the airA formula for compounding state qs ad 250 ml. This expression meansWhat is the brown gas (name and formula) that nitric acid reacting with copper produces? How can you tell that the gas produced in #1 makes an acid in water?

- Aluminum-lithium (AI-Li) alloys have been developed by the aircraft industry to reduce the weight and improve the performance of its aircraft. A commercial aircraft skin material having a density of 2.65 g/cm? is desired. Compute the concentration of Li (in wt%) that is required. The densities of aluminum and lithium are 2.71 and 0.534 g/cm3, respectively.Consider these compounds: A. Al(OH)3 B. Ag3PO4 C. Zn3(PO4)2 D. Ca3(PO4)2 Complete the following statements by entering the letter(s) corresponding to the correct compound(s). (If more than one compound fits the description, include all the relevant compounds by writing your answer as a string of characters without punctuation, e.g, ABC.) Without doing any calculations it is possible to determine that barium phosphate is more soluble than , and barium phosphate is less soluble than . It is not possible to determine whether barium phosphate is more or less soluble than by simply comparing Ksp values.5. Adult oyster shells are composed mainly of calcite, CaCO3. It’s dissolution in water can be described as: CaCO3 (s) ⇌ Ca 2+ + CO32- The surface seawater around Hong Kong has concentrations of [CO32-] = 1 x 10-5 mol/kg and [Ca2+] = 0.01 mol/kg. Will oyster shells dissolve in the seawater?
