The reactivities of the halogens decrease down the group ( At < I < Br < Cl < F). This is due to the fact that atomic radius increases in size with an increase of electronic energy levels. This lessens the attraction for valence electrons of other atoms, decreasing reactivity.
Stir the water continuously, this is the only logical answer. Adding powdered sugar, decreasing the volume, increasing the amount of suga, cooling, all don't make the sugar dissolve quicker.
Answer:
A. Occur in gaseous and liquid state
Explanation:
The choice that is not a characteristic of minerals is that minerals occur in gaseous and liquid state.
All minerals are solid inorganic compounds.
- A mineral is an inorganic compound that is formed naturally.
- They have a definite and specific chemical composition.
- Minerals are the building blocks of rocks.
- When minerals aggregates together, they form different rock types.
- There is no known mineral that is in fluid state.
- All minerals are solids.
- Examples are quartz, kaolinite, gypsum e.t.c
