Vegetation cover serves as the most efficient and effective method to curb sediment loss. The roots of plants like grass interlink soil particles, aiding in erosion resistance, particularly against runoff water. Vegetation absorbs the force of raindrops, preventing soil particle detachment. Additionally, plants can lie flat resembling shingles on a roof, enabling runoff to travel over the soil rather than disturbing it.
Tall, erect vegetation functions as a barrier against wind, diminishing its force so that it cannot dislodge soil particles from the ground surface.
Answer:
Can you rank the following chemical substances in order of their absolute entropies (So) from lowest (1) to highest (5) at a temperature of 298 K?
a. Al (s)
b. H2O (l)
c. HCN (g)
d. CH3COOH (l)
e. C2H6 (g)
Explanation:
Entropy quantifies the level of disorder within a system.
In solids, the entropy is significantly lower compared to liquids and gases.
The typical order of entropy is:
solids < liquids < gases
In the substances listed, liquid water notably exhibits strong intermolecular hydrogen bonding.
This results in water having comparatively lower entropy.
Next in line is acetic acid.
Among the gaseous components, ethane has higher entropy than HCN due to its weaker intermolecular interactions.
HCN involves some hydrogen bonding.
Thus, the order of entropy is:
Al(s) < CH3COOH (l) < H2O(l) < HCN(g) < C2H6(g)
Answer:
Is it true that you shouldn't wash your hair, drink cold water, eat ice cream, or exercise during your period? Please explain your answer.
No, this is not accurate; doing any of these activities is perfectly fine. None of them affects us because they are not connected to our bodily systems. Also, I apologize for any language errors as I utilized Google Translate.
I hope this is helpful :)
The total number of moles of oxygen contained in the sample is 11.3 moles. Explanation: Based on the stoichiometry of the compound, 1 mole of
corresponds with 4 moles of CO or can be stated as 1 mole containing 1 mole of Ni, 4 moles of C, and 4 moles of O, leading to the conclusion that moles of C and O are equal. Therefore, since there are 11.3 moles of carbon present, there are likewise 11.3 moles of oxygen.
