20.2 grams of solid carbon react with 14 L of sulfur dioxide gas at STP, producing liquid carbon disulfide and carbon monoxide gas. The reaction to produce one mole of carbon disulfide required 239 kJ/mol. Now is the time to give specific facts for this assignment. Write down as many correct and distinct facts as you can, given the above information. The fact cannot be stated in the original problem. Each fact written needs to be distinct from your prior statements. Facts can be concepts and they can be values you can calculate from the given information.

Chemistry Assignment Writing ServiceQUESTION 3 [30 marks] PROCESS SAFETY Chlorine gas at the outlet of the electrolysis unit is dried and compressed to be used in different chemical processes. If possible, liquefaction of chlorine should be avoided because safety precautions for liquid chlorine are more severe than for gaseous chlorine. However, liquefaction can be necessary for reason like purification, storage or transport. Chlorine liquefaction is performed by compression and cooling. Liquid chlorine is stored in pressure storage tanks. The tanks are pressurized by gaseous chlorine or by a handling gas suitable for this application, e.g., nitrogen Figure 1: Chlorine storage tank1. Perform a risk evaluation (HAZOP study) and formulate possible countermeasures for the following process upsets a. Too high pressure b. Too much weight of the tank 2. Discuss layers of protection (LOPA) embedded in the storage unit

MAY BE Useful information: When an ionic solid such as calcium hydroxide, Ca(OH)2(s), is added to water it will dissolve according to the following equilibrium:Ca(OH)2 (s) H2O(l)  Ca2 (aq) 2 OH-(aq)The solubility product constant Ksp for the equilibrium can be written asKsp = [Ca2 ] * [2*OH-]2The hydroxide ion concentration, [OH-] can be determined via titration with HCl. First, we make a saturated solution of Ca(OH)2, and remove the undissolved solid by gravity filtration. Subsequently we determine the hydroxide ion concentration, [OH-] via titration with standardized HCl.Now we can calculate the solubility product constant, Ksp. For our equilibrium[Ca2 ] = x, and [OH-] = 2xKsp = x * (2x)2 = 4x3Once the Ksp is known, we can relate it to Gibb’s Free Energy, G.G = – RT ln KspR is the ideal gas constant (R=8.314 J/mol K(, and T is the temperature of the experiment in Kelvin [K].In this experiment we will determine G for dissolving Ca(OH)2 in water at two different temperatures. To determine the change in standard enthalpy and entropy we useG = H-TSWhere G is change in Gibbs Free Energy, H is the change in enthalpy, and S the change in entropy for the equilibrium process. T is the temperature in Kelvin. We generally assume that H and S do not change significantly with temperature. We will determine G at two different temperatures, yielding two sets of G, substituting the two sets of equations and then solve for H and S.Materials: 0.1050 M HClMagnetic stirrer with stir bar50 ml BurettePhenolphthalein indicator10 ml Volumetric pipette 150 ml Erlenmeyer flask Saturated Ca(OH)2 solution at room temperature Solid Ca(OH)2

3) one way to analyze for the amount of phosphorus In a rock is to precipitate the phosphorus as MgNH4PO4, which is them heated to turn it into Mg2P2O7. What mass of Mg2P2O7 will be obtained from 1.679g sample of a rock that contains 86.52% Ca3(PO4)2 ( and no other source of phosphorus) if this analysis is done? 4) a mixture of Cu2O and CuO contains 0.468 g of Cu. What is the mass of CuO in the mixture?5) Hydrogen cyanide gas can be made by two step process. First ammonia is reacted with oxygen gas to give nitrogen monoxide and water vapor. In the next step nitrogen monoxide is reacted with methane (CH4) to give hydrogen cyanide gas. The by products in the second step are water and hydrogen gas. When 22.1 g of ammonia and 28.6g of methane are used how many grams of hydrogen cyanide can be produced?

The electron configuration of an atom determines the number of electrons available to participate in bonding with another atom. One method of depicting the valence electrons that an atom has is through the Lewis structure. For the second part of your initial post, pick an element from the periodic table of elements. Identify the valence electrons and the orbitals in which they reside.
