Ammonia is produced by the millions of tons annually foruse as a fertilizer. It is commonly made from N₂ and H₂ by theHaber process. Because the reaction reaches equilibrium beforegoing completely to product, the stoichiometric amount of am-monia is not obtained. At a particular temperature and pressure,10.0 g of H₂ reacts with 20.0 g of N₂ to form ammonia. When equilibrium is reached, 15.0 g of NH₃ has formed. (a) Calculatethe percent yield. (b) How many moles of N₂ and H₂ are presentat equilibrium?

A student carried out the synthesis of aspirin as described using 3.0 g or salicylic acid and 6.0 ml of sccetic anhydide and abtained 1.306 g of asprin Calculate the theoreteical yield of aspirin Calculate the percent yield of aspirin.

C6​H12​O6​ O + 6O2​  →→ 6CO2​ + 6H2​O  + Energy ​Determine the limiting reactant and how much of that limiting reactant you would need in order to use up all of the non-limiting reactant. Assume you have 25 grams of glucose and 40 grams of oxygen as reactants for the following photosynthesis reaction: A) Glucose is the limiting reactant; You would need .1388 moles of glucose to use up all of the Oxygen (non-limiting reactant).    B Glucose is the limiting reactant; You would need .208 moles of glucose to use up all of the Oxygen (non-limiting reactant).    C Oxygen is the limiting reactant; You would need 1.25 moles of Oxygen to use up all of the glucose (non-limiting reactant).    D Oxygen is the limiting reactant; You would need .8328 moles of Oxygen to use up all of the glucose (non-limiting reactant).

Set up the following reactions. Each reaction has to be balanced. a) Ethane reacts with Oxygen in a combustion reaction. b) The Photosynthesis-Reaction. c) Sulfuric acid reacts with sodium hydroxide-solution. d) CuSO4*5H20 is heated. This leads to the evaporisation of all crystal water. e) A solution of calcium hydroxide is treated with gaseous carbon dioxide. One of the two reaction products is chalk.

All one question

Your lab partner accidentally mixed some sodium chloride with your sample of Epsom salts (M9SO,·7H,O). You want to make a standard solution of magnesium ion, and this is the only sample of a magnesium salt you have. To determine the amount of magnesium salt in the mixture, you heat 100.00 g to drive off the water of hydration and find that the anhydrous mixture has a mass of 73.25 g. What is the mass in grams of the original salt mixture that you must add to 1.000L of water to make a 0.1000 M solution of Mg2+ ion?
