Answer: Simple squamous epithelium is the type of epithelial tissue that lines the air sacs and allows the exchange of substances like gases.
Explanation:
Simple cuboidal epithelium is made up of a single layer of these cube shaped cells that are mostly involved in absorption of substances.
Answer :
(1) act as a reducing agent and act as a oxidizing agent.
(2) act as a reducing agent and act as a oxidizing agent.
Explanation :
Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.
Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.
(1)
In this reaction, 'I' is oxidized from oxidation (0) to (+5) and 'Cr' is reduced from oxidation state (+6) to (+3). Hence, act as a reducing agent and act as a oxidizing agent.
(2)
In this reaction, 'As' is oxidized from oxidation (+3) to (+5) and 'N' is reduced from oxidation state (+5) to (+3). Hence, act as a reducing agent and act as a oxidizing agent.
Answer:
pH = 12.8
Explanation:
HF + NaOH → F⁻ + Na⁺ + H₂O
<em>1 mole of HF reacts with 1 mole of NaOH</em>
<em />
Initial moles of HF and NaOH are:
HF = 0.018L × (0.308mol / L) = 5.544x10⁻³mol HF
NaOH = 0.023L × (0.361mol / L) = 8.303x10⁻³mol NaOH
That means moles of NaOH remains after reaction are:
8.303x10⁻³mol - 5.544x10⁻³mol = <em>2.759x10⁻³moles NaOH</em>
Total volume is 18.0mL + 23.0mL = 41.0mL = 0.0410L
Molar concentration of NaOH is
2.759x10⁻³moles NaOH / 0.0410L = 0.0673M = [OH⁻]
pOH = - log [OH⁻] = 1.17
As pH = 14 - pOH
<em>pH = 12.8</em>
