  • Tetrahedral Distortion Lab Report

    1010 Words  | 5 Pages

    Tetrahedral distortion is defined as the change in both the distance of bond and angle of bond are present. The degree of distortion with respect to the beta phase can be related to the tetrahedral tilt angle and the intertetrahedral bridging angle. While for tetrahedral tilting, there is only change in the angle of the bond and no change in bond distance. When there is an increase in temperature, the Fe-O-P bridging angles increases and the tetrahedral tilt angles decreases. As the temperature increases

    Due to water’s polar structure, ions in some compounds attract and form bonds with water molecules, forming hydrates. A hydrate is a salt that has water molecules trapped within its crystals. Every hydrate has a certain number of water molecules weakly bonded to the salt as follows: salt • number of water molecules Anhydrous salts are salts that can form hydrates but which have had all the water driven off, usually by heat. By heating the Copper (II) sulphate hydrate until its color changes from

  • Why Does Calcium Chloride Effective?

    408 Words  | 2 Pages

    Calcium chloride is commonly used as the main ingredient in road dust control products because it has the ability to hold on to moisture for a longer period of time. Therefore, this keeps the dust from becoming airborne. Since the dust remains settled on the ground this creates a smooth surface that is easy to drive on. One of the reasons why calcium chloride is so effective is due to how it is handled prior to use. If the chemical substance is stored incorrectly this can ruin your roads and create

    consistent orange flame. Potassium omitted purple light, magnesium showed no change in color, and calcium produced a red light. When heated, due to the excited movement of the electrons specifically in the metal ions within the compound, flame colors are produced (2). The structure of a sodium ion in its ground state is 1s22s22p6 (6). When heat is applied, its electrons then gain energy giving them the ability to jump into empty orbitals at high levels (2). Once the electrons reach a higher level however

  • KCL: Ionic Bonds

    386 Words  | 2 Pages

    KCL is an ionic bond. This is because potassium (K) has a charge of +1 and chorine having a charge of -1. K gives one electron to chlorine, this makes it so both of them have a full valence shell. GeCl4 is a covalent bond, due to it being hard to separate its 4 valence electrons so Germanium shares its 4 valance electrons to Chlorine therefore making 5 full outer valence shells. BrCl is a covalent bond. Chlorine has a high electronegativity then bromine, and is a dipole-dipole which indicates to
