Identify the type of reaction (synthesis, decomposition, etc

Figure 12-4 shows how two frequency spectra, each composed of 4 points, arecombined into a single frequency spectrum of 8 points. This synthesis must the interlaced decomposition done in the time domain. In other words, thefrequency domain operation must correspond to the time domain procedure of two 4 point signals by interlacing. Consider two time domainsignals, and . An 8 point time domain signal can be formed by twosteps: dilute each 4 point signal with zeros to make it an

Ca(NO3)2·4H2O, CaO, Ca(OH) 2, CaCO3, and Ca(CH3COO)2 ·H2O were used as precursors for synthesis of calcium oxide sorbents of CO2. Calcium acetate based sorbents resulted in the best adsorption performance of CO2. In a wide operation window of 600-800°C, this sorbent has shown high adsorption of CO2 90% of which were achieved at the first 15 minutes of adsorption period. Calcium acetate based sorbents also showed great regenerability in multi adsorption-desorption cycles. After 25 cyclic adsorptions/desorption, the sorbent still had a conversion of 64% during adsorption of CO2. High conversion and good regenerability of calcium acetate based sorbents are attributed to relatively large volume of mesopores and macropores produced during multi steps decomposition of synthesis. Sorbents from other precursors showed poorer performance since they had smaller pores, less pore volume and lower BET surface area. These high performance calcium oxide sorbents have great potential for numerous high temperature applications such as fuel cells, carbon sequestration, novel reactors, and coal gasification etc.

Synthesis
In this experiment you will perform four classes of chemical reactions:
• synthesis — a reaction combines two or more substances to create a new one. For example, iron rusting is a synthesis reaction.
• decomposition — a reaction in which a substance breaks apart into simpler constituents.
• single displacement — a reaction in which one substance in a molecule is replaced by another.
• double displacement — a reaction two molecules swap atoms to form new substances.
After performing these reactions, you will identify the products that result and write a balanced chemical equation to represent each of those reactions.

However, the capacity of self-heating during decomposition often provides ideal conditions for obligate or facultative thermophilic actinomycetes able to grow at temperatures above 40oC. Actinomycetes play an important role in the decomposition of plant and other material especially in the degradation of complex and relatively recalcitrant polymers. They degrade lignin, cellulose and lignocellulose. There is evidence that actinomycetes are involved in the degradation of many other naturally occurring polymers in soil such as hemicellulose, pectin, keratin, chitin and fungal cell wall material. Actinomycetes from rhizosphere suppress the growth of pathogens. Isolates from rhizosphere hydrolyses starch. Some rhizosphere isolates can synthesise gibberellin like substances.
