Answer:
Option B
Explanation:
- For Option A the state is not changing but just has different look now.
- For Option B the state is changing from gas to liquid drops due to cold glass
- For Option C it hasn't changed state as both corn and flower is solid
- For Option D paper and ash are both solids
Therefore our answer must be Option B
Basically all of the elements found in Group I of the periodic table also have this property. The ability to easily give up a single valence electron.

when hot copper metal reacts with chlorine gas it forms CuCl2 which is yellow in colour.
non metal carbon burns in Oxygen gas they form non metal oxide.
Dry air is a mixture of nitrogen, oxygen, carbon dioxide etc.
air is a mixture of gases 78% nitrogen an 21% oxygen and other components.
There are 48.72 g Fluorine ions

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison
%F in CaF₂ :
mass of Fluorine :
So mass Fluorine ions(2 ions F in CaF₂⇒Ca²⁺+2F⁻) :
