Correct option:
The statement "America is the world’s number one producer of natural gas derived from shale oil" is True.
Shale gas:
- Shale, a form of sedimentary rock, is used to make shale gas, which is natural gas.
- Over the past ten years, shale gas has gained importance as a natural gas source in the United States. Interest has also grown in possible shale gas reserves in Canada, Europe, Asia, and Australia.
- With large production in the US and Canada, North America is the region that produces the most shale gas globally. Only Argentina and China have so far produced shale gas on a commercial basis outside of the US and Canada.
- The environmental dangers associated with shale gas production like, Induced seismicity from hydraulic fracturing has been known to cause earthquakes in three different places across the world and leaks of extraction waste and chemicals into water systems, the release of greenhouse gases during extraction, and the pollution brought on by the poor processing of natural gas have led to its suspension in numerous nations.

The student's test average is : 0.92
Total score obtained = 369
Number of tests = 4
Since Each test is exactly 100 points ;
The total score obtainable is (100 × 4) = 400
Average = score obtained / total score obtainable
Average = 369 / 400
Average = 0.9225
Average = 0.92

Answer:
C8H8O2
Explanation:
The molecular formula of a compound is simply a multiple of the empirical formula as shown below:
Molecular formula => [C4H4O]n
From the question given, we were told that molar mass of the compound is 136g/mol. This implies that:
[C4H4O]n = 136
Now, let us find the value of n in order to obtain the desired result. This is illustrated below:
[C4H4O]n = 136
[(12x4) + (4x1) + 16]n = 136
[48 + 4 + 16]n = 136
68n = 136
Divide both side by the coefficient of n i.e 68
n = 136/68
n = 2
Therefore the molecular formula is
=> [C4H4O]n
=> [C4H4O]2
=> C8H8O2
Answer:
Cold air holds less water vapor than warm air. This is why warm climates are often more humid than cold ones: Water vapor remains in the air instead of condensing into rain. Cold climates are more likely to have rain, because water vapor condenses more easily there.
