Is oxygen radioactive or stable? Is O2 considered a molecule or a compound? Are ionically bonded compounds mixtures? Explain. Is copper wire a compound, mixture, or element? Is oxygen an isotope? What are examples of mixtures in chemistry? For deep sea diving, what gas do divers mix with...
many substances, such as wood, burn in air and burn even more vigourously in pure oxygen). Mixtures do not have fixed precise melting and boiling points (which elements and compounds do have), but instead mixtures melt / freeze and boil / condense over a range of temperatures according to...
Apart from searching for new structures of potential drugs, there is a second approach based on a combination of two or more well-known pharmacophores into one molecule with synergistic activities. Nasr et al. [13] described synthesis and antimicrobial effects of tiophene, acrylamide, aryl...
Carbon dioxide is: a) an element. b) a mixture of carbon and oxygen. c) a compound. d) homogenous. Matter: Matter is anything that occupies space and has mass. Matter can be classified as pure substances or mixtures. The pure substances include the elements...
carbon monoxide (CO) molecule Hemoglobin is a protein molecule with 4 protein sub-units (2 alphas and 2 betas) Carbon monoxide binds very strongly to the iron atoms in hemoglobin, the principal oxygen-carrying compound in blood. The affinity between CO and hemoglobin is200 times strongerthan th...
These chemical factors associated with the CA molecule enable the elimination of free radicals, preventing the production of ROS (reactive oxygen species) as well as the induction of DNA oxidation of cancer cells present in various types of cancer, such as Hepatocarcinoma (HCC). The following ...
