Although they were formerly called the inert gases, at least the heavier elements of Group 8 do form relatively stable compounds. For example, xenon combines directly with elemental fluorine at elevated temperatures in the presence of a nickel catalyst. Xe(g) + 2F2 (g) → XeF4(s) What is the theoretical mass of xenon tetrafluoride that should form when 155 g of xenon is reacted with 197 g of F2? Theoretical mass= g What is the percent yield if only 143 g of XeF4 is actually isolated? Percent yield = %

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 H,O that can be produced by combining 81.4 g of each reactant? 4 NH, (g) + 50,(g) 4 NO(g) + 6 H, O(g) > g H,O mass:

Cryolite (Na3AlF6) is used in the production of aluminum from its ores. It is made by the reaction 6 NaOH + Al2O3 + 12 HF → 2 Na3AlF6 + 9 H2O Calculate the mass of cryolite that can be prepared by the complete reaction of 287 g Al2O3.

What is the mass in grams of H₂ that can be formed from 88.2 grams of NH, in the following reaction? 3 2 NH₂(g) → 3 H₂(g) + N₂(g)

How many moles of Al are necessary to form 52.2 g of AlBr₃ from this reaction: 2 Al(s) + 3 Br₂(l) → 2 AlBr₃(s) ?

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 H,O that can be produced by combining 84.6 g of each reactant? 4 NH,(g) + 5 0,(g) → 4 NO(g) + 6 H,O(g) g H,O mass: 61 Sunny

If 9.9 × 10²⁵ molecules of CO₂ are produced in a combustion reaction, what is the mass in kg of CO₂ that is produced?

Consider the reaction of solid P₄ and chlorine gas to form gaseous phosphorus trichloride. The balanced chemical equation is P₄(s) + 6 Cl₂(g) → 4 PCl₃(g). How many grams of phosphorus trichloride can be formed from 419.7 grams of P₄ based on the balanced chemical equation?

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 50.1 g of each reactant? 4 NH3(g) +50₂(g) -> 4 NO(g) + 6H₂O(g)
