Answer: Therefore, the volume of a 0.155 M potassium hydroxide solution is 56.0 ml
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of 
solution = 0.338 M
= volume of solution = 25.7 ml
= molarity of 
solution = 0.155 M
= volume of solution = ?
= valency of = 1
= valency of = 1
Therefore, the volume of a 0.155 M potassium hydroxide solution is 56.0 ml
Answer:
ㅤㅤCellular respiration is a metabolic pathway that breaks down glucose and produces ATP. ... respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle ... glucose and are shuttled to the electron transport chain by electron carriers ... into a two-carbon molecule bound to Coenzyme A, known as acetyl CoA.

Explanation:
Answer:
6 electrons.
Explanation:
An atom of oxygen has six electrons in its outermost energy level, and these are called valence electrons.
The answer is Joule. Kilograms and Grams is a unit for weight
We calculate the molar concentration [Cl⁻] using stoichiometry. MnCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MnCl2 that dissolves.
MnCl2(s) --> Mn+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.68 mol MnCl2/1L × 2 mol Cl⁻ / 1 mol MnCl2 = 1.4 M
The answer to this question is [Cl⁻] = 1.4 M
