Ammonia forms 1:1 adducts with a variety of Lewis acids such as I 2, phenol, and Al(CH 3) 3. Ammonia is a hard base (HSAB theory) and its E & C parameters are E B = 2.31 and C B = 2.04. Its relative donor strength toward a series of acids, versus other Lewis bases, can be illustrated by C-B plots .

Oil exploration in 2005 by the US Geological Survey revealed that the North Cuba Basin could produce about 4.6 billion barrels (730,000,000 m 3) to 9.3 billion barrels (1.48 × 10 9 m 3) of oil. In 2006, Cuba started to test-drill these locations for possible exploitation.
On average, about half of the volumetric concentration of landfill gas is CH 4 and slightly less than half is CO 2. The gas also contains about 5% molecular nitrogen (N 2), less than 1% hydrogen sulfide (H 2 S), and a low concentration of non-methane organic compounds (NMOC), about 2700 ppmv.
