Esophagitis, esophageal varices, gastritis, cirrhosis or gastric ulcers for example, may bleed and produce coffee-ground vomitus. When unaccompanied by melena, hematemesis or a fall in hemoglobin with corresponding urea rises and creates an unstable reaction, and other causes of coffee ground vomitus need to be elucidated; for example, gastric stasis, bowel obstruction or ileus, that can cause ...
The health effects of coffee include various possible health benefits and health risks. [ 1 ] A 2017 umbrella review of meta-analyses found that drinking coffee is generally safe within usual levels of intake and is more likely to improve health outcomes than to cause harm at doses of 3 or 4 cups of coffee daily.

Halogenation of benzene where X is the halogen, catalyst represents the catalyst (if needed) and HX represents the protonated base. A few types of aromatic compounds, such as phenol, will react without a catalyst, but for typical benzene derivatives with less reactive substrates, a Lewis acid is required as a catalyst.

In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
