Endometriosis is a disease in which cells like those in the endometrium, the layer of tissue that normally covers the inside of the uterus, grow outside the uterus. [8] [9] It occurs in humans and a limited number of menstruating mammals.
Sodium percarbonate (Na 2 H 3 CO 6), an adduct of hydrogen peroxide and sodium carbonate ("soda ash" or "washing soda", Na 2 CO 3). Dissolved in water, it yields a solution of the two products, that combines the degreasing action of the carbonate with the bleaching action of the peroxide. Sodium perborate (Na 2 H 4 B 2 O 8).
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus.The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.
[59] [60] In vitro, cannabidiol inhibited the activity of voltage-dependent sodium and potassium channels, which may affect neural activity. [61] A recent study using X-ray crystallography showed that CBD binds inside the sodium channel pore at a novel site at the interface of the fenestrations and the central hydrophobic cavity of the channel.
or a very strong base such as sodium hydride: CH 3 CH 2 OH + NaH → CH 3 CH 2 ONa + H 2. The acidities of water and ethanol are nearly the same, as indicated by their pKa of 15.7 and 16 respectively. Thus, sodium ethoxide and sodium hydroxide exist in an equilibrium that is closely balanced: CH 3 CH 2 OH + NaOH ⇌ CH 3 CH 2 ONa + H 2 O
The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.

Halite (/ ˈ h æ l aɪ t, ˈ h eɪ l aɪ t / HAL-yte, HAY-lyte), [7] [8] [9] commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (Na Cl).Halite forms isometric crystals. [10]
