In order to determine the theoretical yield, we must first find the limiting reactant (reagent), which will determine the greatest possible amount of product that can be produced.

Lithium produces less lithium nitride than nitrogen gas. Therefore, the limiting reactant is lithium, and the theoretical yield of lithium nitride is
20.9 g
.
Explanation:
Answer:
24.47 L
Explanation:
Using the general gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = 0.0821 Latm/molK
T = temperature (K)
According to the provided information in this question,
P = 1.0 atm
V = ?
n = 1 mol
T = 25°C = 25 + 273 = 298K
Using PV = nRT
V = nRT ÷ P
V = 1 × 0.0821 × 298 ÷ 1
V = 24.465 ÷ 1
V = 24.465
V = 24.47 L

The smallest unit of a compound that still has the properties of the compound is called a molecule.
Molecules are made up of two or more atoms. It has the physical and chemical properties of a compound.
The atoms in a molecule are connected by different chemical bonds. Intramolecular forces hold the atoms together in a molecule. Types of intermolecular forces are London dispersion forces (LDF), dipole-dipole interactions, and hydrogen bonding.
There are different types of molecules like diatomic molecules, homonuclear diatomic molecules, heteronuclear, and polyatomic molecules.
Examples of molecules include CO, CL2, NH3, O3, etc.
