Which of the following solids is soluble in water, conductive in solution, brittle and could have a melting point of 2800 C? (a) Ionic solid (b) Molecular solid (c) Covalent solid (d) Graphic solid Is the ionic solid Pb(OH)_2 soluble or insoluble...
Write the correct formula for ammonium sulfate. Is it a molecular or ionic compound?Ammonium SulfateIt is an inorganic sulfate and it is obtained when ammonia reacts with sulfuric acid. This solid is very soluble in water and is commercially useful. It is used as a soil...
The ionic composition of brines used to culture haloarchaeal strains GN-2 and GN-5 (which was determined to an accuracy level within the low-mM range; Javor, 1984) was used to calculate the water activity of these media (Figure 1a). The values obtained were consistent with the conversion...
Water is a polar molecule that forms many hydrogen bonds with itself and other polar substances, therefore,water is an excellent solvent for ionic and polar compounds. Unfortunately, benzophenone has no hydrogen bonding sites that are important for solubility in water. Even though the carbonyl group...
In recent years the molecular structure of the interface between biomolecules and water has been increasingly seen as an important component of sub cellular organization and function5,6,7. Water molecules localized to a hydration shell in the vicinity of a biomolecular “surface” are sometimes ...
1), is by no means realistic for the hyper-mobile water, because the molecular shape and chemical nature of the protein surface are very complex. In addition, it is not known yet where water molecules are hyper-mobilized on the actin surface (see below) or how they exchange with those ...
Molecular dynamic simulationIonic liquids can protect nitrile hydratase from thermal instability.Interactions of ionic liquids with surface of the enzyme rigidifies the structure.The active site arrangement remains native in ionic liquids at high temperatures....
A molecule's molecular weight is the sum of all its constituent atoms' atomic weights. Avogadro's number (6.02214076 × 1023) is the number of molecules that constitutes the atomic weight of a molecule in grams (g). For example, water is two hydrogen atoms with a weight of 1 g each an...
Is the compound calcium bromide ionic, molecular, or an acid? Write its formula. Write the formula and formulate if the given compound is ionic or covalent, acid or hydrate. Mn(HCO3)3 Write the formula of the ionic compound formed from Co2+ and OH-. Write the formula o...
How about water as a solvent for CH_3CH_2F? Are there any differences in how water would be able to solvate these two compounds? Explain your reasoning. Why is the ionic compound NaCl (table salt) able to dissolve in a glass of the molecular compound water (H_2O)? Explain why ...
