Deduce the Lewis acid and the Lewis base in the given reaction. CO2(g) +H2O(l)---H2CO3(aq) Classify each of the following substances as a Lewis acid, Lewis base, either a Lewis acid or base, or neither a Lewis acid or base a) BF3 b) Fe3+ c) HS- d) CO e) CCl...
In this system, carbon dioxide (CO2) combines with water to form carbonic acid (H2CO3), which in turn rapidly dissociates to form hydrogen ions and bicarbonate (HCO3-) as shown in the reactions below. The carbon dioxide-carbonic acid equilibrium is catalyzed by the enzyme carbonic anhydrase;...
Cardiomyocytes plated on coverslips or six-well plates were transfected with miR inhibitors or siRNAs as aforementioned, washed, and incubated in a simulated ischemia buffer that contained 118 mM NaCl, 24 mM NaH2CO3, 1 mM NaHPO4, 2.5 mM CaCl2, 1.2 mM MgCl2, 20 mM sodium la...
and distinct spectral signatures have been detected which allow for phase discrimination between amorphous and crystalline ices. These features may be used to glean further information as to the structure of the ice as a function of substrate temperature and rate of deposition: for example, rapid de...
