The herd of cattle is cows. Cows are cattle and a herd is a group of them.
The Milliliters that occupy when its pressure is 755 mmhg is calculated using Bolyes law fomula
that is P1v1 = p2 V2
p1= 735mmhg
V1= 350 Ml
P2= 755 mm hg
V2= ?
from the formula above V2 is therefore= p1V1/P2
= 350 x735/755= 340.73 Ml
C. Hydropower would need dams to be built, and this will prevent fishes from going upstream.
Answer;
Silver is acting as oxidizing Agent.
Explanation:
The reaction is as follow,
<span> Fe + 3 AgNo</span>₃ → Fe(NO₃)₃<span> + 3 Ag
In above reaction the Iron's oxidation state has changed from 0 to +3, i.e.
Fe</span>⁰ → Fe³⁺ + 3 e⁻
It shows that Iron has lost 3 electrons, Hence, it is oxidized and has transferred 3 electrons to 3 mole of Ag⁺ to reduce it into Ag. Therefore, Iron is acting as reducing Agent.
While, In reaction the Silver's oxidation state has changed from +1 to 0, i.e.
3 Ag⁺ + 3 e⁻ → 3 Ag
It shows that Silver has gained one electron, Hence, it is reduced and has gained 3 electrons from 1 mole of Fe to oxidize it into Fe³⁺. Therefore, Silver is acting as oxidizing Agent.
The correct answer for the given question above would be option B. HYDROGEN. The form that has the greatest number of <span>strong covalent bonds and is therefore the backbone of organic molecules including carbohydrates, proteins, lipids and nucleic acids is HYDROGEN. Hope this answers your question.</span>
