Answer:
Explanation:
Oleic acid originates from an unsaturated fatty acid with 18 carbon atoms and one double bond, which can be found in olive oil and many other vegetable and animal oils and fats. Its economic importance includes the production of soap making and cosmetics etc.
The line-bond structure of the given oleic acid in the question can be found in the attached below.
Answer: True
Explanation:
The speed of light in a material medium depends on its molecular structure, in particular its electromagnetic properties, electrical and magnetic permeability. These properties may have different values for different wavelengths or frequencies of the incident light.
In this way,<u> the speed of light depends on the medium and reaches its maximum value in a vacuum</u>, so that, it will be lower in a material medium . In the vacuum (or in the air) the speed of light is 3 x 10⁸ m / s and in any other medium its value is lower.
<u>To characterize the particularities of the propagation of light in the media</u>, the refractive index is introduced
,
n = c / v
where c is <u>speed of light in a vacuum</u> and v is t<u>he speed of light in the medium</u> considered
. So the speed of light in a medium is given by the refractive index whose value is always greater than 1.
<h3>Answer:</h3>
1.0 × 10⁻⁶ M (Option-A)
<h3>Solution:</h3>
Data Given:
pH = 6
[H⁺] = ?
Formula Used:
As we know pH is given as,
pH = -log [H⁺]
and,
[H⁺] = 10^-pH ----- (1)
Putting value of pH in eq. 1,
[H⁺] = 10⁻⁶ ∴ 10 = Antilog
[H⁺] = 1.0 × 10⁻⁶ M
Answer: The partial pressure of the Kr is 320 mm Hg.
Explanation:
According to Raoult's Law , the partial pressure of each component in the solution is equal to the total pressure multiplied by its mole fraction. It is mathematically expressed as
where, 
= partial pressure of component A
= mole fraction of A
= total pressure
mole fraction of Krypton = 
Thus partial pressure of the Kr is 320 mm Hg
