One of these products is produced in the product-forming step of the Eschenmoser fragmentation, as well as the second step of the Arndt–Eistert reaction. The formation of this general type of product is characteristic of cheletropic elimination reactions. The occurrence of reactions that produce another product of this type may be detected by observing milky limewater. The strength of (*) di·azo·methane as a methylating agent may be attributed to its ability to form these products. Reactions that form these products are highly entropically favorable and have chemical equations with an up-arrow next to the relevant product. It's not a salt, but reactions that form these products include the reaction of alkali metals with acids and the decomposition of sodium azide. For 10 points, baking soda and vinegar combine to release what small, often diatomic molecules whose production results in bubbling? ■END■
