The answer is (3). The reaction that can occur at the anode is oxidation reaction which will lose electrons. So (1) and (2) are not correct. For (4) Fe3+ can not lose electrons again.
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴
Answer:
the stabilization of the negative charge in orbitals with higher s character
Explanation:
Acetylide anion is a carbon anion compound or popularly called carbanion. Now Acetylide anion is sp hybridized. However acetylide anion tends to be more acidic as we move from sp³ to sp, hence acidicity increases, which makes sp to have the highest acidity and become the most stable.
So, we can conclude that the acetylide anion is more acidic due to the stabilization of the negative charge in orbitals with higher s character and as the s character increases, acidic nature of acetylide anion also increases.
The number of liters of 0.90% NaCl solution one can make from 470 milligrams of table salt is 52.22 mL (milliliters) or 0.0522 L (liters)
In order to determine volume (number of liters) one can make from 470 milligrams of table salt (NaCl)
First, we will convert the unit of concentration to grams per liter or grams per milliliter
From the question, the desired concentration is 0.90% NaCl (9 grams of salt per 1000 grams of solution)
Since the density of the NaCl solution is 1.0 g solution/mL solution, then
9 grams of salt per 1000 grams of solution means 9 grams of salt per 1000 mL of solution.
From the question, mass of the table salt = 470 milligrams = (470/1000) grams
∴ Mass of the table salt = 0.47 grams
Now,
If there are 9 grams of salt per 1000 mL of solution
Then, there will be 0.47 grams per
mL of solution
∴
mL
mL
mL
mL
∴ There will be 0.47 grams per 52.22 mL of solution
Hence, the number of liters of 0.90% NaCl solution one can make from 470 milligrams of table salt is 52.22 mL (milliliters) or 0.0522 L (liters)

Answer:
D. association with bacterial species.
Explanation:
Methanogens -
These are the organisms , that falls under the category of the prokaryotes , in the domain archaea .
Methanogens are a type of microorganism , which is capable to produce methane as one of the by product during a hypoxic condition .
These organisms are found in the wetland , inside the digestive system of the humans and animals .
They have an important space for the treatment of the anaerobic wastewater .
Hence , from the question ,
The correct option is d.
