Amino acid molecules contain both acidic (COOH) and basic (NH2) sites. Q:Four different solids were tested for conductivity. Because both components of each compound change partners, such reactions are sometimes called double-displacement reactions. Sodium Iodine is a common inorganic salt and taken as the important source of iodine as well. Sodium iodide | NaI or INa | CID 5238 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities . A:A question based on introduction to chemistry that is to be accomplished.

Q:predict the reaction type (single or double displacement) positive ion from one reactant will combine with the negative Combination 3. The easiest way to make that kind of prediction is to attempt to place the reaction into one of several familiar classifications, refinements of the five general kinds of reactions (acidbase, exchange, condensation, cleavage, and oxidationreduction reactions). Then the resulting reaction is H2 (aq) + 2 OH (aq) 2 H2O (). WebQC is a web application with a mission to provide best-in-class chemistry tools and information to chemists and students. Some say that Sodium is more reactive than Calcium.
