Answer:
A) 6.48 g of OF₂ at the anode.
Explanation:
The gas OF₂ can be obtained through the oxidation of F⁻ (inverse reaction of the reduction presented). The standard potential of the oxidation is the opposite of the standard potential of the reduction.
H₂O(l) + 2 F⁻(aq) → OF₂(g) + 2 H⁺(aq) + 4 e⁻ E° = -2.15 V
Oxidation takes place in the anode.
We can establish the following relations:
- 1 Faraday is the charge corresponding to 1 mole of e⁻.
- 1 mole of OF₂ is produced when 4 moles of e⁻ circulate.
- The molar mass of OF₂ is 54.0 g/mol.
The mass of OF₂ produced when 0.480 F pass through an aqueous KF solution is:
Answer:
The relative humidity in Raleigh, NC
You can search it up online. Search up what is climate change and it will give you "the weather conditions prevailing in an area in general or over a long period." (On bing)

Answer:
the answer to your question is B) Monotreme.
Explanation:
most mammals do not lay eggs, they give birth. But, monotreme mammals including the duck-billed platypus do in fact lay shelled eggs.
C. Electrons fill orbitals in order of increasing orbital energy.
The volume increased to 0.64 L on increasing the temperature to boiling point of water.
<u>Explanation:</u>
One of the important laws used for understanding the kinetics of gas particles is Charle's law. It states that the volume occupied by gas molecules will be directly proportional to the Kelvin temperature of the molecules at constant pressure.
Volume ∝ Kelvin Temperature at constant Pressure
So, in this case, the initial volume of the container in which Nitrogen gas is kept is given as 0.5 L and the initial temperature of the Nitrogen gas is said to be 18°C.
Now the container is heated to boiling point of water which is 100°C, then the volume occupied by the gas should increase as per Charle's law.
Since here V₁ = 0.5 L
T₁ = 18°C = 18 + 273.15 = 291.15 K
T₂ = 100°C = 100 + 273.15 = 373.15 K
Thus, the volume increased to 0.64 L on increasing the temperature to boiling point of water.
