The sugar is a polar molecule and same as the water. The polar water molecule will attract the positive and negative part of the sugar and lead the sugar dissolve.
In electroplating with silver, silver cyanide is used in the electrolyte rather than other compounds of silver such as silver nitrate, AgNO3, because the cyanide ion, CN-, reacts with silver ion, Ag+, to form the complex ion Ag(CN) -.

<h3>What is a ketone?</h3>
A ketone can be defined as a class of organic compound that typically comprises a carbonyl group in which an atom of carbon (C) is covalently bonded to an atom of oxygen (O).
In this context, we can infer and logically deduce that a structure diagram which completes the table of physical structures of the main functional groups is as follows:

Answer:
2 atm
Explanation:
Chemical reactions are carried out at a certain rate. Sometimes that rate is quite slow, so we want to speed things up, which is usually used by increasing temperature, increasing pressure or adding a catalyst (a substance that increases the rate without changing itself).
If this is the case, then, when writing a chemical equation, we state these special conditions over a right arrow.
Now let's look at the answers:
- 25°C is a value and unit of temperature
- ∆ is a symbol that denotes change
- 2 atm is a value and unit of pressure (atmosphere is old unit for pressure)
- Pt is a chemical symbol for platinum, an element often used as a catalyst.
So, the correct answer is C) 2 atm
