<span>the si unit of temperature is its degree celsius because its online you could've just looked it up </span>
Explanation:
For the given values of 
we will have the values of 
as follows.
As, 
Therefore,
= 2.15, 
= 7.20
= 12.38
Now, at pH 6.50
; 
At pH = 2.15; 
; 
At pH 7.20; 
; 
Hence, we can conclude that most abundant species is 
and the second most abundant species is 
.
Answer:
2.96 L
Explanation:
We apply the Ideal Gases Law to determine this:
P . V = n . R . T
Firstly we need to know the pressure for the 2.25 moles
P . 1.80L = 2.25 mol . 0.082 L.atm/mol.K . 298K
(We convert T°C to T°K, 25°C + 273 = 298K)
P = (2.25 mol . 0.082 L.atm/mol.K . 298K) / 1.80L
P = 30.5 atm
So now, we apply the pressure value for the new conditions:
30.5 atm . V = 3.7 mol . 0.082 . 298K
V = (3.7 mol . 0.082 . 298K) / 30.5atm = 2.96 L
Some will die at a young age.
Answer:
Bromocresol green.
Explanation:
Bromocresol green is known as a pH-sensitive triphenylmethane family dye and we can use it for distinguishing between two solutions pH. Below the 3.8 pH containing solution will show yellow color and above 5.4 pH containing solution will show the blue color.
So, a solution which is having pH 3.5, will show the yellow color and in a solution which is having pH 5.5, will show the blue color.
