the reaction of 309 kg CH3OH with 543 m3 CO(g) at 1 atm and 175 °C?

To produce zinc metal, carbon monoxide reacts with zinc (I1) oxide according to: Zno + CO - Zn + CO2 The carbon monoxide, however, is initially prepared from: 2C+ 02 → 200 How many grams of zinc metal (Zn) may be prepared if If 81.0g of C is used with excess amount of ZnO? Your answer should be numerical and neglect units (e.g., if you calculate 3.5g then input 3.5).

The extraction of aluminum metal from the aluminum hydroxide found in bauxite by the Hall-Héroult process is one of the most remarkable success stories of 19th century chemistry, turning aluminum from a rare and precious metal into the cheap commodity it is today. In the first step, aluminum hydroxide reacts to form alumina Al2O3  and water:   2Al(OH)3(s) + Al2O3(s) ->  3H2O(g) In the second step, alumina Al2O3  and carbon react to form aluminum and carbon dioxide:   2Al2O3(s) +  3C(s) + 4Al(s) ->  3CO2(g) Suppose the yield of the first step is 74.%  and the yield of the second step is  76.% . Calculate the mass of aluminum hydroxide required to make  4.0kg  of aluminum.   Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.

If exactly 4.089 moles of propanol (C3H8O)  is combusted in the presence of excess oxygen what is the mass of O2 used in the reaction? The molecular weights of all reactants and products are: C3H8O: 60.09 g/mol O2: 31.998 g/mol H2O: 18.016 g/mol; CO2 : 44.01 g/mol. Enter your answer in the units of g, do not enter the unit itself.

The reaction of Ca(s) with N₂(g) has a percent yield of 68.005% under certain conditions. Assuming excess Ca(s) and STP conditions, how many Liters of N₂(g) are required to produce 3.004 mols of Ca3N₂(s) under the same conditions? 3 Ca(s) + N₂(g) →→→ Ca3N₂(s) • Please report your answer to 2 decimal places. If your last digit(s) is/are a 0 and Canvas drops them, that is okay.

Find the Mass to Mass Stoichiometry Calculutation using this formula:  CaS5 + HCl → S + CaCl2 + H2S  whereas here are the other given: Raw Materials: 500 g calcium polysulphide and 1.5 kg hydrochloric acid Actual Yield: 343.4g precipitated sulfur

A) What mass of ammonia gas can be produced from a reaction between 565.0g H₂ and 880.0g of N₂ through the Haber-Bosch reaction? B) What mass of the excess reagent remains? N2(g)+3H2(g)-->2NH3

How many moles of NO₂ would be required to produce 4.70 moles of HNO₃ in the presence of excess water in the following chemical reaction? 3 NO₂(g) + H₂O (l) → 2 HNO₃(g) + NO(g)

90.0 of a certain Compound X, known to be made of carbon, hydrogen and perhaps oxygen, and to have a molecular molar mass of 180./gmol, is burned completely in excess oxygen, and the mass of the products carefully measured: product mass carbon dioxide 13.20g water 5.40g Use this information to find the molecular formula of X.

7) The most important reaction that allows our cars to do work is octane (CSH18) combustion 2 C8HI8 + 25 02 à 16 C02 + 18 H20 a) Theoretically speaking, if we fully combust 3.0 kg of octane, and keep the products at STR, what volume of gas do we expect to be produced? b) If the % yield for this combustion reaction is 90%, what is the actual volume? 8) Name two characteristics that describe real gases and not ideal gasses. 9) a) A climber takes a mole of ideal qgas to the top of Mount Everest, where the pressure is 304 torr and the temperature is subzero at -17° C. What is the volume of the gas? b) The gas taken to Mount Everest is oxugen gas. What is the root mean square velocity of gas molecules in that sample of gas? 10.) a) An 8.00L tank at 7.3° C is filled with 24 g of dinitrogen monoxide (N2O) and 8.2 g of sulfur hexafluoride gas (SF6). What is the mole fraction of sulfur hexafluoride? b) What is the ratio between the rates of effusion of sulfur hexafluoride and dinitrogen…
