A simple Bohr diagrams for elements A, B, and C. Introduction: The basic unit of matter that has the properties of a chemical element is called atom. Atom is made up of subatomic particles (neutrons, protons, and electrons). The substance that is made from one type of atom is called as an element. Every element has a unique chemical symbol, atomic number, and atomic mass.

Show your work, include units, and report the correct number of significant figures for all calculations. 1. According to Planck's equation, the energy of a monochromatic light beam depends on its or 2. A photon can interact with an electron in a molecule, atom or ion, in which the electron is elevated from a electronic state to a state. 3. Because electronic states are quantized, absorption of quanta always occurs at a character- istic 4. The amount of light (or the number of photons) absorbed depends on several factors, including how many electrons undergo the electronic transition. In a solution, this depends on the optical path and the of the solution. 5. A calibration plot for a particular absorbing species is constructed according to the Beer- Lambert's law and the equation of the best-fit straight line is y = 9.41x. What is the concentration of a solution of the same species if its absorbance is measured to be 0.603?

Time Mg (s) + 2 HCI (aq) + MgCl, (ag) + H, (g) The reaction between solid magnesium and hydrochloric acid is represented by the equation. A student combines 0.1 mol of Mg (s) with 0.2 mol of HCI (ag) and monitors the amount of Mg (s) as the reaction proceeds. The student conducts the experiment once with a single chunk of Mg (s) and once with Mg (s) pellets. Assuming that the mass of Mg (s) is plotted for both experiments, which curve represents the mass of Mg (s) for the experiment that uses Mg (s) pellets? Curve A, because the reaction rate is faster when the surface area increases. B Curve B, because the reaction rate is slower when the surface area decreases. Curve C, because the reaction rate is slower when the surface area decreases. D Curve D, because the reaction rate is faster when the surface area increases.
