1. a common way to understand if a mechanism is correct is to use deuterium (d = 2h) in place of hydrogen in a reaction (the method is called isotopic labeling). if dcl in d2o replaced hcl and d2so4 replaced h2so4 and so on for all solvents in this reaction, for which mechanisms would would expect deuterium to be present in the double bond of fumaric acid? explain how your arrived at your prediction using the mechanisms provided.

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.

100 points answer quick the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
