Answer:
Stalagmites
Sinkholes
Stalacites
Explanation:
These features are created because the ground water dissolves solid rocks and move the solid rocks, dissolve solutions beneath the ground water gradually and therefore enlarging the cracks, which eventually form a cave. Ground water carries minerals which are then deposited and can form stalagmites or stalactites. If a stalactite and stalagmite combine together, they usually form a column.
Fluorine (F) would be least likely to form a cation out of potassium, fluorine, chlorine, and nitrogen.
- A cation is a positively charged atom (or molecule) that has lost electrons (or electrons).
- The tendency for electropositive elements to lose electrons and produce cations is greater. On the left side of the periodic table, these are often metals.
- Going down a group increases electropositivity, or the propensity to lose electrons and generate cations. and decreases across a period. In the given examples:
- Potassium, K is an alkali metal and will lose electrons readily to form a cation.
- Nitrogen (N), Fluorine (F), and chlorine (Cl) are all nonmetals that prefer to accept electrons and form anions instead. F is the most electronegative i.e. it will gain electrons and form F- rather than F+.

So the question ask that how to prepare 20ml of the liquid mixture having a denstiy of 2.7 g/cm and the best answer, base on the data you have given and further formulation of a solution, the answer would be CHCL3=11.73ml and CHBr3 = 8.268 ml. I hope you are satisfied with my answer
The darn answer u nimbisol is the opposite
The amount if protons is the same as the amount of electrons, so it would be 8. The charge is -2. Look at oxygen in the periodic table.
