Answer:
Hg∧2+ has a negative standard entropy because the ions are highly solvated in aqueous phase; smaller the ionic size, the more highly it is surrounded by solvated ions. Therefore it will be in highly ordered state hence the entropy decreases.
Hg2 ^2+ has a positive standard entropy because the ionic size of Hg^2+ is smaller than Hg2 ^2+, so therefore the Hg^2+ is highly solvated and that means that it is in highly ordered state. Hg2 ^2+ is not highly solvated so it will have a positive entropy
Explanation:
The values of standard entropy of aqueous ions has a negative standard entropy because the ions are highly solvated in aqueous phase; smaller the ionic size, the more highly it is surrounded by solvated ions. Therefore it will be in highly ordered state hence the entropy decreases.
Hg2 ^2+ has a positive standard entropy because the ionic size of Hg^2+ is smaller than Hg2 ^2+, so therefore the Hg^2+ is highly solvated and that means that it is in highly ordered state. Hg2 ^2+ is not highly solvated so it will have a positive entropy
Answer:
The answer is B
Explanation:
The area surrounding the nucleus is called the electron cloud which holds the electrons, so with the power of deduction its B. 0-0

1. How will you make the soda sweetest ever?
What makes soda sweet is the "sucrose" that is being added in it. This is also known as "table sugar." It is a combination of "glucose" and "fructose." In order to make your soda the sweetest ever, make sure you add more sucrose.
Since most sodas are already supersaturated, you may heat the sugar and water in order to increase the process of dissolution. This will <u>prevent sugar from settling at the bottom</u> and will make your soda the sweetest ever.
2. How will you make the soda have lots of fizz?
Carbon dioxide makes the soda fizz. When it combines with water, it causes "carbonic acid" which is then forced inside the bottle of soda (under high pressure). In order to make the soda have lots of fizz, it is important to consider the <u>amount of sugar and salt that you add. </u>
Soda is not only supersaturated with sugar, but it is also supersaturated with carbon dioxide. Adding sugar and salt allows the carbon dioxide to hold on to the tiny bumps<em> (nucleation site) </em>of the sugar. This will then form bubbles. So, the more sugar and salt you put, the more fizz or bubbles will result.
3. How will you make the soda tart?
The soda tarts are made by using syrup. The best syrup to use is barrel-aged syrup (combining sugar and water and allowing it to rest for two days under room temperature). Next, combine the syrup with the lemon juice. If you are making cherry soda tart, then it is best to add cherry juice as well. Combine them all together in a cocktail shaker, then chill. <em>(Not sure about this, but I hope it helps.)</em>
Answer:Soluble
Explanation:Soluble:(of a substance) able to be dissolved, especially in water.
Answer:
t = 2 seconds
Explanation:
It is given that,
Mass of a boy, m = 50 kg
Initial speed of boy, u = 0
Final speed of boy, v = 8 m/s
Force exerting by another boy, F = 200 N
Let t is the time of contact. The force acting on an object is given by :
F = ma
a is acceleration
So,
So, the contact time is 2 seconds.
