Synthesis and reactions. Mustard gas is the organic compound with formula (ClCH 2 CH 2) 2 S. In the Depretz method, mustard gas is synthesized by treating sulfur dichloride with ethylene: SCl 2 + 2 C 2 H 4 → (ClCH 2 CH 2) 2 S. In the Levinstein process, disulfur dichloride is used instead: 8 S 2 Cl 2 + 16 C 2 H 4 → 8 (ClCH 2 CH 2) 2 S + S 8

For example, the overall equation for photosynthesis: CO 2 + H 2 O → C 6 H 12 O 6 + O 2. The glucose molecule is more complex than either carbon dioxide or water. Remember, the key to identifying a synthesis or direct combination reaction is to recognize two or more reactants form a more complex product molecule. Answer and Explanation: The balanced reaction equation is: CH4(g)+H2O(g) ⇋CO(g)+3H2(g) C H 4 ( g) + H 2 O ( g) ⇋ C O ( g) + 3 H 2 ( g) The equilibrium constant expression in terms of partial Synthesis gas obtained from coal gasification tends to have a H 2:CO ratio of ~0.7 compared to the ideal ratio of ~2.

Zinc Chloride is a chemical compound, which is composed of zinc and chlorine. It is a hygroscopic white crystalline ionic salt with the chemical formula ZnCl 2. Zinc Chloride is soluble in mediums such as water, glycerol, ether and alcohol.

Synthesis gas (syngas), mainly constituted by carbon monoxide (CO) and hydrogen gas (H2), is produced mostly through biomass gasification and methane reforming. In the last decade, the thermochemical route to produce ethanol and higher alcohols from syngas has been gaining space as a possible route to produce synthetic fuels and additives. Synthesis gas is a very important chemical intermediate for many relevant processes including the production of methanol and Fischer-Tropsch synthesis of synthetic fuels. Syngas is currently produced by the endothermic steam reforming of methane or by homogeneous oxidation in autothermal reforming.
