using physical and chemical properties. Physical properties are characteristics of a substance. Two types of physical properties are quantitative and qualitative. Quantitative is a property that has an amount or can be measured such as hardness‚ solubility‚ and viscosity. Qualitative is a physical description of matter such as color‚ clarity‚ and state. Chemical properties are characteristics of a substance which allows it to behave in a specific manner. A few types of chemical properties are combustibility

by 2050 the reef may be nothing but a coral graveyard if emission levels do not settle and another bleaching does not occur. With the second bleaching of the Great Barrier Reef occurring so early the toxicity levels on the reef are too great to be repaired naturally. This example of chemical bleaching should be noted in history as a reason for retiring the practice of using man made chemicals on reefs to promote their

Chemical Bonding Lab Chemical compounds are combinations of atoms held together by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point

Consider the importance of the characters names in Kindertransport I think that in Kindertransport the writer‚ Diane Samuels uses the names of the characters as a huge way of showing their personalities and their life’s worth. The very first character that we are introduced to is Eva‚ now this is the younger and former self of the later introduced Evelyn. The name ‘Eva’ is a Hebrew name which is biblical and means ‘life’ but also ‘God’s grace’. This is very fitting as when Eva is introduced to

Chemical reactions involve the making and breaking of bonds. It is essential that we know what bonds are before we can understand any chemical reaction. To understand bonds‚ we will first describe several of their properties. The bond strength tells us how hard it is to break a bond. Bond lengths give us valuable structural information about the positions of the atomic nuclei. Bond dipoles inform us about the electron distribution around the two bonded atoms. From bond dipoles we may derive electronegativity

DIFFDiffusion of Chemicals * Diffusion-is the process whereby particles of liquids‚ gases‚ or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. The rate of diffusion depends on the size of the surface area to the volume in the cell. The higher the surface area of cells in relation to their volume‚ the quicker diffusion takes place. Experiment on Diffusion Aim: to
