Answer : Option 4) Region of the most probable electron location.
Explanation : As per the electron cloud model of the atom, an orbital is a region where the probability of finding an electron is highest. According to this model which was used to identify the probable location of the electrons when they go around the nucleus of an atom.
This electron cloud model was different from the older Bohr atomic model by Niels Bohr.
Answer: The mass of potassium bromide that must be dissolved in the same mass of X to produce the same depression in freezing point is 58.2 grams
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte)
= freezing point constant =
m= molality = 
Let Mass of solute (KBr) = x g
Thus the mass of potassium bromide that must be dissolved in the same mass of X to produce the same depression in freezing point is 58.2 grams
Element 87 francium have the highest atomic size, so in short the closest element to francium have the high atomic size.
No
Explanation:
Not all organic substances are soluble in water and will not conduct electricity. Only polar organic compounds are soluble in water and will conduct electricity.
- The general rule of solubility is that like dissolves likes.
- Polar compounds will only dissolve other polar compounds too. Water is a polar solvent.
- Non-polar compounds will only dissolve in non-polar compounds too.
- Since water is a polar organic compound, only polar organic compounds will dissolve in it.
- Not all organic compounds are polar.
- When a compound dissolves in water, it produces ions that makes it able to conduct electricity.
- Fats and oil are insoluble in water
