Lattice energy for formation of CaC 2 ( s ) is to be determined. Concept introduction: The pictorial representation of formation of ionic solids from its constituent elements is known as Born-Haber cycle. Following are the steps required to draw Born-Haber cycle of any ionic compound: Step 1: Solid metal is converted into gaseous isolated atoms. It takes place by process called sublimation. Step 2: Gaseous molecules are broken down into separate atoms. Energy is supplied to break molecules apart and this is called bond dissociation energy . Step 3: Isolated metal atoms are converted into respective cations with the help of ionization energy. Step 4: Anions are formed from gaseous atoms with the help of electron affinity . Step 5: Ionic compound is formed by the combination of cation and anion. Energy is released in this process.

Answer 1

Question

Formula Formula Bond dissociation energy (BDE) is the energy required to break a bond, making it an endothermic process. BDE is calculated for a particular bond and therefore consists of fragments such as radicals since it undergoes homolytic bond cleavage. For the homolysis of a X-Y molecule, the energy of bond dissociation is calculated as the difference in the total enthalpy of formation for the reactants and products. X-Y → X + Y BDE = Δ H f X + Δ H f Y – Δ H f X-Y where, ΔHf is the heat of formation.

Help with a periodic table task.' Procedure Part 1: Customizing a Periodic Table Use a textbook or other valid source to determine which elements are metals, nonmetals, metalloids (called semimetals in some texts), alkali metals, alkaline earth metals, transition metals, halogens, and noble gases. Download and print a copy of the Periodic Table of Elements. Use colored pencils, colorful highlighters, or computer drawing tools to devise a schematic for designating each of the following on the periodic table: Group numbers Period number Labels for these groups: alkali metals, alkaline earth metals, transition metals, inner transition metals (lanthanides and actinides), other metals, metalloids (semimetals), other nonmetals, halogens, and noble gases Metals, nonmetals, and metalloids Note: Write the group and period numbers and color/highlight each element for categorization. Be sure to include a key for the schematic. Take a photo of the completed periodic table and upload the…
