Determine the Limiting Reactant (LR)and the Mass (In G)of Nitrogen

question 55

Multiple Choice

Determine the limiting reactant (LR) and the mass (in g) of nitrogen that can be formed from 50.0 g N₂O₄ and 45.0 g N₂H₄.Some possibly useful molar masses are as follows: N₂O₄ = 92.02 g/mol,N₂H₄ = 32.05 g/mol. N₂O₄(l) + 2 N₂H₄(l) → 3 N₂(g) + 4 H₂O(g)

• A) LR = N₂H₄, 59.0 g N₂ formed
• B) LR = N₂O₄, 105 g N₂ formed
• C) LR = N₂O₄, 45.7 g N₂ formed
• D) LR = N₂H₄, 13.3 g N₂ formed
• E) No LR, 45.0 g N₂ formed

Flat Tract

A large piece of land with minimal to no slope, often used in agriculture or construction due to its ease of modification.

River

A large natural stream of water flowing in a channel to the sea, a lake, or another river, often a central feature in ecosystems and human civilizations.

Lower Reaches

The downstream part of a river close to its mouth where it meets a larger body of water.

Aquifer

An underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt) that can yield significant quantities of water.
