Decomposition and Synthesis Reactions - Video & …

Either theory requires the synthesis of organic matter, which necessarily involves the participation of an energy source. Although there are many plausible energy sources for the generation of organic compounds, one of the most conspicuous sources on Earth is its internal heat, which is released in many environments. Such is the case of anomalously high thermal gradients around volcanoes and volcanic hot springs (Lathe, 2004, 2005), which can be subaerial and submarine—some with temperatures that may range from 90° to > 400 °C (Russell and Hall, 1997; Kelley et al., 2001). Processes driven by external sources for energy include many other interfaces such as those between rocks, water, air, and snow-air (Muller and Schulze-Makuch, 2006). From the point of view of prebiotic chemistry, high temperature gradients would have provided the necessary energy flux to promote chemical reactions. But at the same time, however, such gradients could have been harmful to organic compounds, thus promoting the degradation of the synthesized products (Muller and Schulze-Makuch, 2006).

synthesis reactions, decomposition reactions, exchange reactions, and reversible reactions.

The basic difference between the synthesis and decomposition reactions is predictable from their names. Synthesis, which in this case means to join, results in two or more base substances binding together on a molecular level to create a single compound. In contrast, a decomposition reaction results in a breakdown of individual components to yield separate substances, much as the name entails.

Chlorate was present in drinking-water, either as a manufacturing by-product or from decomposition reactions occurring during storage.

The most common and commercially available BFC comprise esters (-nitrophenyl, pentafluorophenyl, -hydroxysuccinimide, sulfo--hydroxysuccinimide), isothiocyanates, maleimides, hydrazides, α-haloamides for the reaction with nucleophilic functional groups (-NH2, -SH, -OH) of vector molecules and formation of amide, urea, thiourea, Schiff-base, or thioester bond []. Methods have been developed for the conjugation with peptides by solid-phase peptide synthesis (SPPS) resulting in defined position and number of chelate moieties. The outcome of the conjugation in solution wherein peptides and proteins comprise several reactive sites is very often a mixture of bioconjugate molecules with various content of the chelator. Such heterogeneity may cause the interpretation ambiguity of the performance of such imaging agents. Regioselective conjugation to antibodies was achieved by enzymatic reaction with lysine and glutamine residues using bacterial and human tissue transglutaminase as catalysts [].

However, production of chlorine dioxide, its decomposition and reaction with NOM lead to the formation of by-products such as chlorite (ClO2-), a compound that is of health concern.

Unlike the other disinfectants, the major chlorine dioxide DBPs are derived from decomposition of the disinfectant as opposed to reaction with precursors.

Serpentinization has been proposed as a generator of drastic chemical, redox, pH, and thermal gradients (Russell et al., 2013). In this way, the weathering of mafic and ultramafic rocks constitutes a sink for CO2 (Berndt et al., 1996), because minerals present in basalts (olivine, plagioclase and augite) are highly reactive with CO2. It is likely that hydrothermal systems of the early Earth were largely hosted by olivine-rich ultramafic rocks (e.g., komatiites) (Russell et al., 2010). The formation of serpentine, brucite, and magnetite produces large amounts of hydrogen and methane (Kelley, 1996). The sustained production of hydrogen creates strongly reducing environments yielding a favorable environment for organic synthesis (Holm et al., 2015). This process could have contributed to the subsequent formation of organic compounds on early Earth.

Models for the synthesis of organic compounds include those associated with a variety of mineral-catalyzed reactions such as water-rock reactions (e.g., serpentinization), Fischer-Tropsch reactions, and FeS-driven synthesis. Experiments listed on Table 3 show the synthesis of different types of amino acids, as well as lipids and hydrocarbons.

synthesis, and decomposition reactions

There are numerous experiments proposed to test the role of hydrothermal vents in prebiotic synthesis. A review of the literature (Tables 2, 3 and 4) indicates several types of experiments that can be performed. The first group is related to decomposition experiments, sometimes referred as stability experiments (Table 2), and comprises the majority of available studies. In these experiments, the decomposition rate of biomolecules, mainly amino acids, is explored. The most surveyed one is the simplest amino acid: glycine. It is noticeable that the inclusion of mineral phases is considered fundamental in breakdown experiments. In this regard, the role of some iron-rich minerals has been explored (e.g., magnetite, fayalite, pyrite, etc.); however, other minerals (e.g., quartz, feldspars, muscovite, calcite) are also used. In this kind of experiments the formation of other amino acids is also pursued. An important finding is that there is an order in the decomposition rates of the selected molecules (Vallentyne, 1964; see Table 2), and that decomposition strongly depends on factors (such as pH, pressure, ionic strength, etc.) other than temperature. Another kind of information that can be obtained by means of these studies is the determination of kinetic parameters (Povoledo and Vallentyne, 1964) in order to predict the behavior of organic reactions.

This lesson is intended for use in a first year Chemistry class and has modifications aligned with the North Carolina Novice High English Language Development objectives. It provides an overview of various types of chemical reactions by allowing students to visually observe examples of synthesis, decomposition, single displacement, and double displacement reactions and to identify certain products by the use of litmus and splint tests.
