Answer:
40/220 ×100=18.6 is all I got I know that by heart so um yea
Explanation:
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
The sand is the residue and a mixture of salt dissolved in water is the filtrate
<u>Answer:</u>
<em>To raise the pH of the solution to 3.10 we have to add 2.34 L of water.</em>
<u>Explanation:</u>
<em>Given that the pH of the solution of HCl in water is 2.5.</em> Here the solution’s pH is changing from 2.5 to 3.10 which means the acidic nature of the solution is decreasing here on dilution. ions contribute to a solution’s acidic nature and contribute to a solution’s basic nature.
The equation connecting the concentration of and pH of a solution is pH=
<em></em>
<em>When the pH is </em>
<em>On dilution the concentration of a solution decreases and volume increases.</em>
<em></em>
<em></em>
<em></em>
<em>Volume of water to be added </em>

Answer:
It leads to new jobs that search for innovative ways to control emissions.
Explanation:
Publishing a report that is a revised list of green house gases by scientists underscores the importance of new new jobs that seek ways of controlling emissions. The publication will inspire scientific research into control of emission of greenhouse gases. This will create new jobs for scientists who will be charged with the responsibility of ensuring that emission of Tue newly discovered greenhouse gasses is greatly reduced.
Several scientists earn a living by actively carrying out research on control of the emission of greenhouse gasses.
