Phosgene is an organic chemical compound with the formula COCl 2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut ...
Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion. Substances that diffuse efficiently in human tissue, e.g., hydrofluoric acid , sulfur mustard , and dimethyl sulfate , may not react immediately, but instead produce the burns and inflammation hours after the contact.
Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...
What does NAD do in the body? NAD helps hundreds of enzymes in the cell do their jobs. "Some of those enzymes are involved in cellular repair, so helping cells that have damage due to UV radiation ...
Most muscle cramps subside within seconds to minutes, although soreness related to the cramps can sometimes last hours to days, per Mayo Clinic. Noted: Building muscle requires a higher protein ...
The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
One doctor told me that there was nothing they could do to treat me. Another asked if I had considered freezing my eggs (because some types of chemotherapy can lead you into early menopause ).
