A frequency dependence of complex dielectric permittivity of polar polymer reveals two sets or two branches of relaxation processes (Adachi and Kotaka 1993), which correspond to the two branches of conformational relaxation, described in Section 4.2.4. The available empirical data on the molecular-weight dependencies are consistent with formulae (4.41) and (4.42). It was revealed for undiluted polyisoprene and poly(d, /-lactic acid) that the terminal (slow) dielectric relaxation time depends strongly on molecular weight of polymers (Adachi and Kotaka 1993 Ren et al. 2003). Two relaxation branches were discovered for i.s-polyisoprene melts in experiments by Imanishi et al. (1988) and Fodor and Hill (1994). The fast relaxation times do not depend on the length of the macromolecule, while the slow relaxation times do. For the latter, Imanishi et al. (1988) have found... [Pg.154]

O Muscle soreness from physical activity is caused by a buildup of lactic acid in muscle tissue. Analysis of lactic acid reveals it to be 40.0% carbon, 6.71% hydrogen, and 53.3% oxygen by mass. Calculate the empirical formula of lactic acid. [Pg.214]

As you can see from Table 6.3, there are many compounds that have the empirical formula CH20. The substance might be formaldehyde, but it could also be lactic acid (found in milk) or acetic acid (found in vinegar). Neither lactic acid nor acetic acid connect the theft to the suspect. Further information is required to prove that the substance is formaldehyde. Analyzing the physical properties of the substance would help to discover whether it is formaldehyde. Another important piece of information is the molar mass of the substance. Continue reading to find out why. [Pg.215]

The molecular formula of the compound contains three empirical formula units. The molecular formula is CjHgOj. The compound is lactic acid, the sour-tasting substance in spoiled mdk. Lactic acid is also produced by active muscles, causing them to feel sore after strenuous activity. [Pg.429]

Lactic acid s empirical formula is C3ILO3, so the carlxtns have a net oxidation number of zero, the same as in glucose (CeHnOe). However, the carbons in lactic acid do not have the same oxidation number. The carboxyl carbon of lactic acid is more oxidized (-t-3) than the methyl carbon at the other end, which has three of its four bonds to hydrogen and therefore has an oxidation number of -3. A key feature of metabolic pathways is that the oxidation of one component is balanced by the reduction of another. The net result is that no electrons are lost or gained in the process. [Pg.117]

Lactic acid (found in sour milk) has an empirical formula of HC3H5O3. A 1.0-g sample of lactic acid required 17.0 mL of 0.65 M NaOH to reach the end point of a titration. What is the molecular formula for lactic acid ... [Pg.380]

Plan We know the mass % of each element and must convert each to an integer subscript. The mass of the sample of lactic acid is not given, but the mass percents are the same for any sample of it. Therefore, we assume there is 100.0 g of lactic acid and express each mass % as a number of grams. Then, we construct the empirical formula as in Sample Problem 3.9. [Pg.82]

Lactic acid, which consists of C, H, and O, has long been thought to be responsible for muscle soreness following strenuous exercise. Determine the empirical formula of lactic acid given that combustion of a 10.0-g sample produces 14.7 g CO2 and 6.00 gH20. [Pg.103]

The designation originated at a time when real significance was attached to the empirical formula Ci(H20)n, which represents these substances as hydrates of the element carbon. Today we are no longer bound by the empirical formula we call deoxyribose CsHioOi and glucosamine CeHisOsN carbohydrates, but not lactic acid CjHsOs. [Pg.256]
