The equation is 2 NH3 (g) ⇀↽ N2 (g) + 3 H2 (g)
Difference in the number of moles delta n = ((3 + 1) - 2) = 4 - 2 = 2
We have an equation Kp= Kc (R x T) ^ (delta n); R is constant and T = 300 K
Kp / Kc = (R x T) ^2 Based on the temperature value (300 K), we can conclude that Kp is Larger.

Atomic radius- a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons.
Electron Affinity-the electron affinityof an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.
Electronegativity-a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.
Lonization energy- qualitatively defined as the amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.
Answer:
83 g
Explanation:
Step 1: Write the balanced equation
2 Fe + 3 S ⇒ Fe₂S₃
Step 2: Calculate the moles corresponding to 95 g of Fe
The molar mass of Fe is 55.85 g/mol.
95 g × 1 mol/55.85 g = 1.7 mol
Step 3: Calculate the moles of S needed to react with 1.7 moles of Fe
The molar ratio of Fe to S is 2:3. The moles of S needed are 3/2 × 1.7 mol = 2.6 mol
Step 4: Calculate the mass corresponding to 2.6 moles of S
The molar mass of S is 32.07 g/mol.
2.6 mol × 32.07 g/mol = 83 g
