All you have to do is research more about this scientist´s theory. Just google: Why wasn´t Wegner´s hypothesis accepted?
Trust me, the answers are there.<span>
</span>Next time just research it.
Wegner´s idea seemed so ridiculous at the time that he was ridiculed by other scientists. The problem was that to his colleagues there seemed no plausible mechanism for how the continents could move through the oceans.
The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine: TRUE
<h3>
What is the book value?</h3>
- Book value is the worth of an asset based on its balance sheet account balance in accounting.
- The value of an asset is determined by subtracting the asset's original cost from any depreciation, amortization, or impairment expenses.
- Traditionally, a company's book value is equal to its total assets minus intangible assets and liabilities.
- In practice, however, depending on the source of the computation, book value may include either goodwill or intangible assets, or both.
- The value inherent in its employees, which is part of a company's intellectual capital, is always overlooked.
- When intangible assets and goodwill are specifically omitted, the indicator is frequently defined as "tangible book value."
Therefore, the statement "the book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine" is TRUE.

Calculate the pH at of a 0.10 M solution of anilinium chloride 
. Note that aniline 
is a weak base with a 
of 4.87. Round your answer to 1 decimal place.
<u>Answer:</u> The pH of the solution is 5.1
<u>Explanation:</u>
Anilinium chloride is the salt formed by the combination of a weak base (aniline) and a strong acid (HCl).
To calculate the pH of the solution, we use the equation:
![pH=7-\frac{1}{2}[pK_b+\log C]](https://tex.z-dn.net/?f=pH%3D7-%5Cfrac%7B1%7D%7B2%7D%5BpK_b%2B%5Clog%20C%5D)
where,
= negative logarithm of weak base which is aniline = 4.87
C = concentration of the salt = 0.10 M
Putting values in above equation, we get:
![pH=7-\frac{1}{2}[4.87+\log (0.10)]\\\\pH=5.06=5.1](https://tex.z-dn.net/?f=pH%3D7-%5Cfrac%7B1%7D%7B2%7D%5B4.87%2B%5Clog%20%280.10%29%5D%5C%5C%5C%5CpH%3D5.06%3D5.1)
Hence, the pH of the solution is 5.1
elements are classified to study their properties and similarities and differences between each other more aqurately
hope it helps...!!!!
Answer:
The answer is A. Polar covalent; negatively
Explanation:
Hydrogen bonds form between molecules containing polar covalent bond the hydrogen bond is been a hydrogen atom of one molecule and a partially negative charged atom of another.
Example 
(water):- It contain a slight positive charge on one side and a slight negative charge on the other.
