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.

Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants and . If you need to include any physical constants, be sure you use their standard symbols
Answer:
Equation that gives the overall equilibrium constant K in terms of the equilibrium constants :
Explanation:
Step 1 :
Expression of an equilibrium constant can be written as:
Step 2 :
Expression of an equilibrium constant can be written as:
The net reaction is:
Expression of an equilibrium constant can be written as:
Multiply and divide ;
So , the equation that gives the overall equilibrium constant K in terms of the equilibrium constants :
