Answer:
Chemical weathering due to water
Explanation:
Since all the water is pulled underground through cracks and crevices on the surface, it makes the limestone plateau have no surface water. Meanig the most likely cause for having the underground of the plateau to change over time is the chemical weathering due to water.
The answer is A.<span>Boron and carbon are likely together in one period because they have very close atomic numbers, while gallium and germanium are likely together in another period because they have very close atomic numbers.

Answer:
The answer to your question is 6.77 atm
Explanation:
Data
Pressure 1 = P1 = 7.5 atm
Temperature 1 = T1 = 65°C
Pressure 2 = P2 = ?
Temperature 2 = T2 = 32°C
Process
-Use Gay-Lussac law to solve this problem
P1/T1 = P2/T2
-Solve for P2
P2 = P1T2 / T1
-Convert temperature to °K
T1 = 65 + 273 = 338°K
T2 = 32 + 273 = 305°K
-Substitution
P2 = (7.5 x 305) / 338
-Simplification
P2 = 2287.5 / 338
-Result
P2 = 6.77 atm
Answer:
Consider each of the following molecules in turn: (a) dimethyl ether, (CH3)2O; (b) trimethylamine, (CH3)3N; (c) trimethylboron, (CH3)3B; and (d) carbon dioxide (CO2). Describe the hybridization state of the central atom (i.e., O, N, B, or C) of each molecule, tell what bond angles you would expect at the central atom, and state whether the molecule would have a dipole moment.
