and her feelings being of the nature of those substances which are powerfully affected by the application of strong waters, she dropped a tear with every drop of negus, and so got on, melting the feelings down, until at length she had arrived at a very pathetic and decent pitch of misery...
are used as medical tracers and in thyroid disease diagnosis and therapy. Iodine compounds are used as germicides, antiseptics, and dyes. Atomic number 53; atomic weight 126.9045; melting point 113.7°C; boiling point 184.4°C; density of gas 11.27 grams per liter; specific gravity (solid, at...

Graphite and diamonds are made up of carbon atoms. Graphite, however, is soft and can be used to write with while diamonds are the hardest substance known to man and are the only substances that can be used to cut other diamonds. What is the main rea...
seedling.Root absorption dominated, stem and leaf absorption is very little, quickly transmitted to plant meristem and leaf, interferes with photosynthesis, resulting in death of weeds.In resistant crops, such as maize, it is broken down by corn ketoenzyme to produce non...
Solubility is a physical property that describes the integration of a solute with a solvent, making a homogenous (uniform) mixture of the two substances. Each substance has its solubility limit, varying from extremely small to extremely large. For example, sodium chloride ...
Such a liquid–liquid transition has been investigated in various substances including water, Al2O3-Y2O3 and network glass formers. However, the nature of liquid–liquid transition is debated due to experimental difficulties in avoiding crystallization and/or measuring at high temperatures/pressures. ...
8-hydroxyquinolines halogenated in the hydroxylated nucleus possess generally a strong bactericide effect, especially against staphylococci and streptococci. Therefore, these substances are used as odorless powders for wounds in the anti- r5 septical treatment of wounds. The best known compound......
"Covalent bonds are simple molecular substances consisting of molecules that are held together by weak forces, so these substances have a low melting and boiling point." Explain this concept. Also, what makes bonds stable?please answer the question and explain the reason...
The final point to note is the relationship between the cytostatic activity of the novel substances and their experimental or theoretical physicochemical properties (Table 1). No correlation was observed between cytostatic activity, GI50, and the DNA binding ability, KB, as the correlation coefficients...
