00 S Nazza .01608 ·018302 3. (part a). You are given 0.104 g of a sample of KwFex(C₂O4)y(H₂O)z. In the laboratory, you titrate this sample with 0.00940 M KMnO4 and you need 10.1 mL of the KMnO4 solution to reach the stoichiometric point. Calculate the mass and moles of [C₂04]²- in the sample. Please show all of your detailed calculations.

In a reaction to produce NaF, 3.50 g of HF and 1.26 of Na2SiO3 are reacted according to the following: Na2SiO3 (s) + HF (aq) →H2SiF6 (aq) + NaF (aq) + H2O (l) (a) Balance the equation.   (b) Calculate the theoretical yield of NaF.   (c) If 0.792 g of NaF is formed, calculate the percent yield.

A 290.3-g sample of ground water is analyzed for calcium. The Ca2+ in the sample is first precipitated and filtered-off as NH4CaPO4·7H2O. This precipitate is dried and heated, releasing water and ammonia to yield anhydrous calcium pyrophosphate (Ca2P2O7). The mass of Ca2P2O7 obtained is 0.0534 g.Give the calcium content of the ground water in parts per million

What mass of Cu(IO3)2 can be formed from 0.650 g of CuSO4 · 5H2O? What mass of KIO3 is needed to convert the copper in 0.2750 g of CUSO4 - 5H2O to Cu(IO3)2?

Ammonia (NH3) is an important compountd is used in large amounts for the manufacture of nitrogenous fertilizers, nylon and many other important compounds. It is manufactured by the catalytic reaction between nitrogen between nitrogen and hydrogen, according to the following equation; N2(g) +H2(g) = NH;(g) When 1.20 mol nitrogen and 1.20 mol hydrogen are mixed together in a closed vessel, 30% of the nitrogen is converted into ammonia. a. Calculate the moles of nitrogen gas that will be present in the vessel? (only 3 decimal places) mol b. Calculate the moles of hydrogen gas that will be present in the vessel? (only 3 decimal places) mol c. Calculate the moles of ammonia gas that will be present in the vessel? (only 3 decimal places) Activate W mol d. What is the number of moles of nitrogen gas that has reacted? (only 3 decimal places) 10:09 Links 18°C 1O 23-Nov-21

Complete combustion of propane (C3H8) produces carbon dioxide and water as products.  C3H8(g) + 5O2(g) --> 3CO2(g) + 4H2O(g) Incomplete combustion produces some carbon monoxide (CO) in place of carbon dioxide (CO2). What is the limiting reactant for incomplete combustion? (A) There is no way to tell (B) Water (C) Propane (D) Oxygen

Ammonium phosphate fertilizer is prepared by the following reaction:3 NH3(g) + H3PO4(aq) ->(NH4)3PO4(s)(a) How many grams of ammonia and phosphoric acid, respectively, are required to produce 1.00 kg of ammonium phosphate, (NH4)3PO4, if the reaction has 100% yield?(b) How many grams of ammonia and phosphoric acid, respectively, are required to produce 1.00 kg of ammonium phosphate, (NH4)3PO4, if the reaction has 85.0% yield?
