<h3>Answer:</h3>
Formic acid is the stronger acid.
<h3>Explanation:</h3>
The strength of an acid is determined by the power of it to dissociate and produce H⁺ ions. Greater the dissociation of an acid, the stronger that acid is. Also, extent of dissociation for particular acid is given by its dissociation constant i.e. Ka.
The greater the Ka value, the stronger an acid is and vice versa.
Calculating Ka value of Pivalic acid:
As,
pKa = -log [Ka]
So,
Ka = 10^-pKa
Putting value of pKa,
Ka = 10⁻⁵
Ka = 1.0 × 10⁻⁵
Calculating Ka value of Formic acid:
As,
pKa = -log [Ka]
So,
Ka = 10^-pKa
Putting value of pKa,
Ka = 10⁻³'⁸
Ka = 1.58 × 10⁻⁴
<h3>Conclusion:</h3>
As the Ka value of Formic acid is greater than Pivalic acid therefore, it is stronger acid than Pivalic acid.
<h2>TIP:</h2>
When comparing strength of acids, the acid with the lowest pKa value is considered the strongest acid and <em>vice versa</em>.
In a heterogeneous mixture, you can clearly see the distinction between the different substances within the mixture. e.g. fruit salad, paella, nachos
in a homogeneous mixture, it is still made up of different substances, but there is no way of distinguishing between them just from appearances. they have the same uniform composition throughout. e.g. salt water; you know it is made of salt and water, but the salt is dissolved uniformly throughout that you cannot tell.
hope that helps :)
Answer:
a

b

Explanation:
From the question we are told that
The pressure of compressed gas is 
The temperature is 
Generally the perfect gas equation is mathematically represented as

substituting 0.08206 L-atm/mol-K for R and 1 mole for n
We have that


Generally the van der Waals equation is mathematically represented as
![nRT = [P + \frac{n^2 * a }{V^2 } ][V - nb]](https://tex.z-dn.net/?f=nRT%20%20%3D%20%20%5BP%20%2B%20%5Cfrac%7Bn%5E2%20%2A%20a%20%7D%7BV%5E2%20%7D%20%5D%5BV%20-%20nb%5D)
=>![1 * 0.08206 *298 = [197.4 + \frac{1^2 * 1.364}{V^2 } ][V - 1 * 3.19 * 10^{-2}]](https://tex.z-dn.net/?f=1%20%2A%20%200.08206%20%2A298%20%20%3D%20%20%5B197.4%20%2B%20%5Cfrac%7B1%5E2%20%2A%20%201.364%7D%7BV%5E2%20%7D%20%5D%5BV%20-%201%20%2A%203.19%20%2A%2010%5E%7B-2%7D%5D)

Answer:
Yes they are triglycerides
Explanation:
Triglycerides are esters derived from glycerol and three fatty acids.
If we look at the structures closely, we will notice that the compounds are composed of glycerol and three fatty acids.
Hence the structures are triglycerides. The first structure is an unsaturated triglyceride while the second structure is a saturated triglyceride.
