The amygdala is an almond-shaped structure deep in the brain that is believed to be a communications hub between the parts of the brain that process incoming sensory signals and the parts that interpret these signals. It can alert the rest of the brain that a threat is present and trigger a fear or anxiety response. The emotional memories stored in the central part of the amygdala may play a role in anxiety disorders involving very distinct fears, such as fears of dogs, spiders, or flying.
Chemical formula for vinegar. Vinegar is composed of about 5% acetic acid. This is the major chemical component of vinegar. The systematic or proper chemical name of acetic acid is ethanoic acid. Vinegar is a weak acid produced by the oxidation of alcohol (ethanol) from wines and ciders by bacteria. It has a pleasant sour taste and is used in cooking or as a condiment.
Vinegar is about 90% water and about 5-10% acetic acid. From what I understand, the acid in vinegar is strong enough to affect and alter organic molecules in the air (what usually makes things stink in a home) while being weak enough that it canât be harmful to anyone (we can eat it and drink it just fine).
