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

question 13

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^-1, N₂H₄ = 32.05 g mol^-1. N₂O₄(l) + 2N₂H₄(l) → 3N₂(g) + 4H₂O(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

Definitions:

Transpiration

The method through which water travels within plants from the roots to tiny openings on the bottom side of the leaves, at which point it transforms into vapor and gets emitted into the air.

Lower Temperatures

Conditions or environments characterized by a reduced degree of heat or a temperature below the average.

Modified Leaves

Leaves that have undergone changes to serve functions other than photosynthesis, such as tendrils or spines.

Store Water

The process or capability of retaining water in bodily tissues, cells, or reservoirs in organisms or systems.
