<u>Answer:</u> The formula of the compound formed between rubidium and fluorine is RbF
<u>Explanation:</u>
Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.
The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.
Rubidium is the 37th element of the periodic table having electronic configuration of
This will loose 1 electron to form ion
Fluoride is the 9th element of the periodic table having electronic configuration of
This will gain 1 electron to form ion
To form compound, 1 rubidium ion is needed to neutralize the charge on fluoride ion
The formation of the given compounds is shown in the image below.
Answer:
Explanation:
Since we are not given the mole fraction of ethanol and water; we will solve this theoretically.
Using Raoult's Law:
For water:
where of water = 12.5 mmHg
Then, the vapor pressure of water:
For ethanol:
and the of ethanol = 32.1 mmHg
Then, the vapor pressure of ethanol:
The total vapor pressure
The total vapor pressure =
