Current Periodic Table

Very Hard

(Originais Teachy 2023) - Question Very Hard of Chemistry

Consider an experiment in which a beam of electrons collides with a target of elemental atoms. During the interaction, the electrons are accelerated and then decelerated, emitting photons with specific energies. Observing the emitted photons allows identifying the elements present in the target. Based on the characteristic X-ray spectrum of an element, which is determined by the transition of electrons from higher energy levels to the K level (n = 1), and considering the knowledge about the electronic structure of atoms, develop an argument that justifies how the location of an element in the periodic table is related to the energy values associated with the electronic transitions observed in the X-ray spectrum.

Consider that a group of students conducted an experiment in the Chemistry laboratory by mixing 10 grams of salt (sodium chloride) in a cup containing 200 mL of water. After the mixture reached homogeneity, we call this mixture a solution. Calculate the concentration in g/L of this solution and identify which of the alternatives below best describes the relationship between solute, solvent, and concentration in the solution?

Organic halides are compounds that have a halogen atom (F, Cl, Br, or I) bonded to a carbon atom belonging to a carbon chain. Their nomenclature depends on the rules established for organic compounds and is important for their identification and study. a) Given the compound 1-chloro-2-methylpropane, identify the functional groups present and write its structural formula. b) From the structural formula, simplify the representation (line formula) of the compound. c) Write the IUPAC nomenclature for the compound with the structural formula CH3CH2CH2Br.
