Answer:
A) 0.95 mol
Explanation:
We will assume the gas given off in the fermentation is an ideal gas because that allows us to use the ideal gas equation.
PV = nRT
First let's convert all measurements to units that we can use
P = 702 mmHg * 1 atm/760 mmHg = 0.92368 atm
V = 25.0 L
R = 0.08206 L-atm/mol-K
T = 22.5 °C +273.15 = 295.65 K
PV = nRT
0.92368 atm * 25.0 L = n * 0.08206 L-atm/mol-K * 295.65 K
n = 0.9518 mol
N₂, H₂, NH₃ are present in the reaction mixture when equilibrium has been obtained.
Balanced chemical reaction: 3H₂ + N₂ ⇄ 2NH₃
Hydrogen (H₂ ) and nitrogen (N₂) are reactants.
Ammonia (NH₃) is product of the reaction.
Reaction goes in both direction, both reactants and product are present.
The amount of substance of reactants and products of reaction do not change when chemical reaction is in chemical equilibrium.
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which not change with time.
Speed of direct and irreversible chemical reaction are equal.

Answer:
Roman numbers are oxidation state of the metals
Because some elements of metals show more than one oxidation state like iron Fe2+ in ferrous and Fe3+ in ferric.
Explanation:
A homogeneous mixture has the same uniform appearance and composition throughout.
A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases.
