Answer:
<u><em></em></u>
- <u><em>pOH = 0.36</em></u>
Explanation:
Both <em>potassium hydroxide</em> and <em>lithium hydroxide </em>solutions are strong bases, so you assume 100% dissociation.
<u>1. Potassium hydroxide solution, KOH</u>
- Volume, V = 304 mL = 0.304 liter
- number of moles, n = M × V = 0.36M × 0.304 liter = 0.10944 mol
- 1 mole of KOH produces 1 mol of OH⁻ ion, thus the number of moles of OH⁻ is 0.10944
<u>2. LIthium hydroxide, LiOH</u>
- Volume, V = 341 mL = 0.341 liter
- number of moles, n = M × V = 0.341 liter × 0.51 M = 0.17391 mol
- 1mole of LiOH produces 1 mol of OH⁻ ion, thus the number of moles of OH⁻ is 0.17391
<u />
<u>3. Resulting solution</u>
- Number of moles of OH⁻ ions = 0.10944 mol + 0.17391 mol = 0.28335 mol
- Volume of solution = 0.304 liter + 0.341 liter = 0.645 liter
- Molar concentration = 0.28335 mol / 0.645 liter = 0.4393 M
<u />
<u>4. </u><em><u>pOH</u></em>
![pOH=-\log [OH^-]=-\log (0.439)=0.36](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D%3D-%5Clog%20%280.439%29%3D0.36)

Answer: the true statements about eicosanoids includes options A,B,D,E
Explanation:
EICOSANOIDS are mostly produced from the precursor arachidonic acid, a C20 polyunsaturated fatty acid. They are broken down within seconds to inactive residues after synthesis.High concentrations of eicosanoids are necessary for effective action.The three major types of eicosanoids includes:
-prostaglandins,
- thromboxanes, and
- leukotrienes.
Depending on the above types mentioned, they play a role in inflammation, pain, fever promotion, blood pressure regulation, and blood clotting. They also influence the immune response and certain respiratory and reproductive processes.
However, eicosanoids are NOT transported in the blood stream to their site of action RATHER they exert their effects on the tissue where they are synthesized.
Answer:A. Circulatory system
Explanation:
After food get digesting the The nutrients gets transported to cells by the blood stream.
According to the context, globalization is the process of integration among individuals, businesses and governments.
<h3>What is globalization?</h3>
It is a historical process of global integration in the economic, political, technological, social and cultural spheres.
It is characterized by a progressive integration and interaction between countries, people and institutions with the expansion of capitalism and democracy, and with values such as multiculturalism and diversity.
Therefore, we can conclude that according to the context, globalization is the process of integration among individuals, businesses and governments.
