If 0.0371 grams of Mg is absorbed in a reaction, how many moles of H2 are produced? Mg+2HCl->MgCl2+H2 Consider the following reaction: C_5H_{12}(g) + 8 O_2(g) rightarrow 5 CO_2(g) + 6 H_2O(g) If a container were to have 16 molecules of C_5H_{12} and 16 molecule...
We examined the effect of internalized IpaB ion channels on distribution of anorganic ions inside macrophages with quantitative electron probe X-ray microanalysis (EPXMA).27 To stimulate endocytosis, we treated BMMs with IpaB or buffer in the presence of 10 kDa Dextran for 10 min and measured ...
Introduction Many papers have suggested that several specific "types" of H2O exist. These have been labelled variously as " zeolitic", " loosely held", "structural", "crystal", "tightly bound" and "external" [1-3]. These labels suggest both the differing apparent energies of H2O as well ...
First, certain nonionic detergents induce many of its conformational changes, including exposure of an N-terminal epitope, translocation to the MOM, and oligomerization (Hsu et al., 1997; Hsu and Youle, 1997). Also, studies with BH3 peptides, or full-length BH3-only proteins, in ...
How many moles are in 4.39 grams of LiCl?Molar Mass:A mole of a substance is defined as that many chemical units of that substance as there are atoms in a pure, 12 grams sample of carbon-12. This constant number is called Avogadro's constant, and the mass contained by a mole of a...
