Question
**Reaction of Lithium with Nitrogen to Form Lithium Nitride**

In this chemical reaction, solid lithium reacts with nitrogen gas to produce solid lithium nitride (Li₃N). The following details pertain to a specific experiment:

- **Reactants Used:**
  - Lithium (Li): 12.3 grams
  - Nitrogen gas (N₂): 33.6 grams

**Tasks and Calculations:**

a) **Calculate the Mass of Lithium Nitride Produced:**

You will need to use stoichiometry to determine the amount of lithium nitride (Li₃N) produced from the given masses of reactants.

b) **Identify the Reactant Used in Excess and Calculate Its Unreacted Mass:**

Determine which reactant is in excess and calculate how many grams remain unreacted after the reaction is complete.
