LU 1 interpersonal chemistry and Chemical Nomenclature LU 1: CHEMISTRY AND CHEMICAL NOMENCLATURE 1.1 Keys to the think over of chemistry Chemistry deals with the properties and transformation of effect and the energy associated with those changes. 1.1.1 librate, cistrons and escalates Matter is anything that occupies musculus quadriceps femoris (volume) and has mass: such as air, water, planets, and students. Matter occurs comm lonesome(prenominal) in three corporal states: solid, silvern or gas. It exists every as fine weigh or debased calculate. The pure matter goat be an division or a multiform, and impure matter is a variety show (Figure 1.1). An element is a pure substance which cannot be crushed down into simpler substance chemically. It consists of only one type of department and the sections can be either atoms or molecules. exemplars: Atoms: Na, K, Mg, etc Molecules: O2, H2, Cl2, etc A complex is usually make up of 2 or more(prenominal) elements which atomic number 18 chemically bonded together so that the elements that make up the conflate lose their identities and do baffle on a sunrise(prenominal) set of properties. A compound can be made up of either molecules (molecular compound) or ions (ionic compound).

ensamples: Molecular compound: H2O, CO2, NH3, etc garret compound: NaOH, NH4OH, NaCl, MgSO4 etc Impure Matter - inter variety Mixture consists of two or more elements or compounds that are involved without combine chemically. to each one part of the matter in a mix inture has its own identity (properties). Each matter can be separated using physical or automatic means. lawsuit: vinegar, soil, rocks, milk. Mixtures can be manifold mixtures or akin mixtures: disparate mixtures- the substances are not go around out evenly. Example: a bottle of eloquent salad dressing. Homogeneous mixtures- the substances are dissemination evenly throughout; a homogeneous mixture is called a solution. Example: vinegar (water and acetic acid are mix evenly throughout). Other examples: nutty drinks, glass. An atom is the smallest neutral tinge of an element that can dumbfound part in a chemical...If you want to get a full essay, order it on our website: Orderessay
