The answer is to test a piece of untreated and treated under same conditions!
Answer:
This question appears incomplete
Explanation:
This question appears incomplete because the data provided only makes it possible to calculate the certainty of the acetic acid content per total volume of the vinegar. Thus, the 4% means for every 100 mL of the vinegar, there is 4 mL of acetic acid present. To calculate the volume of acetic acid in any other volume of vinegar, the formula will be
volume of acetic acid = 4/100 × total volume of vinegar
Answer:
duplet-A set of two things or people
Octet-A group of 8 things or people
Answer : The final temperature of the copper is, ![87.29^oC](https://tex.z-dn.net/?f=87.29%5EoC)
Solution :
Formula used :
![Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})](https://tex.z-dn.net/?f=Q%3Dm%5Ctimes%20c%5Ctimes%20%5CDelta%20T%3Dm%5Ctimes%20c%5Ctimes%20%28T_%7Bfinal%7D-T_%7Binitial%7D%29)
where,
Q = heat gained = 299 cal
m = mass of copper = 52 g
c = specific heat of copper =
= final temperature = ?
= initial temperature = ![25^oC](https://tex.z-dn.net/?f=25%5EoC)
Now put all the given values in the above formula, we get the final temperature of copper.
![299cal=52g\times 0.0923cal/g^oC\times (T_{final}-25^oC)](https://tex.z-dn.net/?f=299cal%3D52g%5Ctimes%200.0923cal%2Fg%5EoC%5Ctimes%20%28T_%7Bfinal%7D-25%5EoC%29)
![T_{final}=87.29^oC](https://tex.z-dn.net/?f=T_%7Bfinal%7D%3D87.29%5EoC)
Therefore, the final temperature of the copper is, ![87.29^oC](https://tex.z-dn.net/?f=87.29%5EoC)
H₂SO₃ is weaker acid than H₂SO₄.
The bonding power of an acid is typically influenced by the size of the "SO₄" atom; the smaller the "SO₄" atom, the stronger the H-A bond. The atoms get larger and the bonds get weaker as you proceed down a row in the Periodic Table, strengthening the acids.
<h3>Describe acid.</h3>
The term "acid" refers to any molecule or ion that can donate a proton (a Brnsted-Lowry acid) or establish a covalent bond with an electron pair (a Lewis acid). The first class of acids is the proton donors, also known as Brnsted-Lowry acids.
Its chemical name is lysergic acid diethylamide, or LSD as it is more often known. Because it has a potent hallucinogenic impact, using it could alter how you see the world and its objects. The effects of LSD are referred to as tripping.
The term "acid" is frequently used to denote aqueous solutions of acids with a pH lower than 8, even though the technical meaning of the term only pertains to the solute.
