Chemical Weathering is the process of decomposition, erosion and spoilage of Solid materials like Building Material, Rocks e.t.c.
This decomposition takes place due to chemical reaction. The chemical present in Air along with water undergo chemical decomposition of Solid materials.
So, first requirement for this process is water, which is present in air called precipitation. Secondly, temperature also play important role.
Result:
<span>The amount of chemical weathering will increase if Temperature and Precipitation Increases.</span>
Answer: Hsub=Hfus+Hvap
Explanation:
The molar heat of vaporization measured in kilojoules per mole, or kJ/mol is the energy needed to make vapor one mole of a liquid. .
The molar heat of sublimation measured in kilojoules per mole, or kJ/mol is the energy needed to sublime one mole of a solid,
the molar heat of fusion measured in kilojoules per mole, or kJ/mol is the energy needed to melt one mole of a solid.
Hess law helps to explain the relationship in physical chemistry stating that the total enthalpy change during the complete course of a reaction is the same whether the reaction is made in one step or in several steps.
In this context Hess’s law helps to see the several steps involved as the heat of sublimation energy is equal to the sum of vaporization energy and fusion energy.
Answer:
Answer is explained in the explanation section below.
Explanation:
Solution:
Note: This question is incomplete and lacks very important data to solve this question. But I have found the similar question which shows the profiles about which question discusses. Using the data from that question, I have solved the question.
a) We need to find the major species from A to F.
Major Species at A:
1. 
Major Species at B:
1.
2. 
Major Species at C:
1.
Major Species at D:
1.
2. 
Major Species at E:
1.
Major Species at F:
1.
b) pH calculation:
At Halfway point B:
pH = pK
+ log[
]/[H
]
pH = pK = 6.35
Similarly, at halfway point D.
At point D,
pH = pK
+ log [H]/[H2]
pH = pK = 10.33
<span>Carboxylic acid.
This is because there is no reducing termini. and if one end is a methyl, that is just hydrocarbons, and the rest must also be hydrocarbons. We can assume that there are no other constituents that are making functional groups and given with what we have this is a carboxylic acid.</span>
