four mirror lines which are absent in unit cell of CaCl2-structured polymorph are present in that of tetragonal rutile structured polymorph. CaCl2 and CaBr2 start as a CaCl2-structured polymorph at room temperature. As temperature approaches the transition temperature‚ the MX6 (M is metal cation while X is the halogen anion) octahedron in the centre of the unit cell rotates about the c-axis‚ causing the rectangular base of the unit cell to

Introduction Different parts of the world have their own cultures‚ and in these cultures there are certain “cultural norms”. Many people decide they would like to go out of a familiar area to study what these “cultural norms” are‚ but the hardest cultural norms to identify‚ are the ones in one’s own culture. For this experiment‚ I decided to sit at a sports bar and see how different groups of people would react to being at a restaurant with multiple NFL games on different televisions. I predicted

Heating Curve Project There are two parts to the project. EVERYONE MUST COMPLETE PART ONE. We can put our personal touch on part two. 1. Label heating curve graph of a substance other than water (NOT WATER‚ make up a substance if you have to‚ but don’t use 0 oC and 100 oC The graph must include: • An illustration (not fancy) of how the molecules are arranged in the solid phase‚ liquid phase‚ gas phase and during the phase changes. • How KE and PE change during different parts of the graph. •

In this lesson you will use teamwork to design a container that would protect a raw egg as it falls to the ground from a height of 8 feet. Your team will receive an egg and a bag of materials. You will be given time to brainstorm how you might construct a protective mechanism for dropping your egg without breaking it. You are only allowed to use the materials in your bag within the time frame allotted. It will be important to work well with your teams in analyzing the materials you are given and

ion was gaining two electrons then the ion would be negative. A negative ion is called an anion. Copper has a boiling point of 3200 Kelvin. This is a very average boiling point for many transitions metals. The melting point for copper is 1357.77 Kelvin. This is also a very normal melting point for many transition metals. The density of copper is 8.96 g/cm3. This is when copper is at room temperature and still a solid. When copper is at melting point the density is 8.02 g/cm3 . This is when copper

The theory is based on an interpretation of demographic history developed in 1919 by the American demographer Warren Thompson

Contrast the electronic spectra of the lanthanide and transition metal ions. Why do the lanthanide ions give rise to very sharp bands in their electronic spectra and why are the magnetic properties of their complexes little affected by the nature of ligands. 4. Give a brief account of separation of lanthanide
