The Ostwald process is used commercially to produce nitric acid, which is, in turn, used in many modern chemical processes. In the first step of the Ostwald process, ammonia is reacted with oxygen gas to produce nitric oxide and water. What is the maximum mass of H₂O that can be produced by combining 93.2 g of each reactant? 4 NH₂(g) +50₂(g) - 1 4 NO(g) + 6H₂O(g) Step 1: Convert 93.2 g NH, to moles and determine the number of moles of H₂O that can form from the available amount of NH₂. 93.2 g NH moles of H₂O produced from NH,: mol NH, mol H₂O

Boron forms an extensive series of compounds with hydrogen, all with the general formula BxHy. To analyze one of these compounds, you burn it in air and isolate the boron in the form of B2O3 and the hydrogen in the form of water. You find that 0.1482 g BxHy gives 0.4221 g B2O3 when burned in excess O2. Determine the empirical I formula of BxHy.

4.69 The pictures below show a molecular-scale view of a chemical reaction between H2 and CO to produce methanol, CH3OH. The box on the left represents the reactants at the instant of mixing, and the box on the right shows what is left once the reaction has gone to completion. Was there a limiting reactant in this reaction? If so, what was it? Write a balanced chemical equation for this reaction. As usual, your equation should use the smallest possible whole number coefficients for all substances.
When sprayed into the flame of a torch, powdered iron reacts with oxygen from the air to form iron(III) oxide, Fe2O3: 4 Fe(s) + 3 O02(g) → 2 Fe2O3(s) If 2.50 g Fe2O3 is formed by this reaction, calculate the maximum total mass of iron metal and oxygen that reacted. Identify the stoichiometric coefficients in this equation. If 10,000 oxygen atoms reacted, calculate how many Fe atoms were needed to react with this quantity of oxygen.
