Answer:
6.8 × 10⁻⁴ mol/L.atm
Explanation:
Step 1: Given data
Solubility of nitrogen gas at 25°C (S): 4.7 × 10⁻⁴ mol/L
Partial pressure of nitrogen gas (P): 522 mmHg
Step 2: Convert the partial pressure of nitrogen to atm
We will use the relationship 1 atm = 760 mmHg.

Step 3: Calculate the value of the Henry's Law constant (k)
We will use Henry's law.

<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
Electronegativity is defined as the tendency of an element to attract the shared pair of electron towards itself in a compound.
When electron is transferred from less electronegative atom to more electronegative atom.
The atom which is more electronegative gains electron and undergoes reduction reaction.
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

During the transfer of electrons, energy is released when an electron looses is potential energy during the transfer.
Hence, the correct answer is Option d.
Answer:
O2
Explanation:
for find the limiting reactant you must calculate the moles of the reactants from the amount that you have and from the MM:
MM FeS2 = 120n = 26.2g / 120g/mol = 0,218 mol
MM O2 = 32n = 5,44g/32g/mol = 0,17 mol
The limiting reactant is
O2
