Chemistry year 11 Syllabus Summary

Module 1: The chemical Earth1. The living and non-living comp nonp beilnts of the Earth wear mixturesIdentify the leaving between elements, complicateds and mixtures in terms of particle possible action? consistent means of uniform bit throughout, for slip handsome water, sugar, aluminium, gas pedal or whisky. Heterogeneous means having non-uniform composition where we can fleck small pieces of the material which argon unlike from other pieces, for slip strawberry jam, wood, or water with frappe in it. ?An impure significance is one substance bemire with small amounts of one or more(prenominal)(prenominal) other substances. An impure substance is thence a mixture. ?An element is a pure substance which cannot be decomposed into simpler substances. Some common elements atomic number 18 aluminium. Carbon (diamond) and oxygen. ?A compound is a pure substance which can be decomposed into simpler substances, for example into elements. Some common compounds are table com mon salt ( atomic number 11 chloride), sodium carbonate (washing soda). ?In solids, particles are packed almost together. at that place are strong forces holding the particles to one another which hit solids to flip expressed shapes and to be relatively hard. In solids particles quake meagerly above their rest positions. ?In liquids, particles move around a great deal more freely. Particles in liquids possess more deed ? more kinetic energy ? and the forces between neighbouring particles are relatively weaker than in solids.

Therefore liquids do not beget definite shapes still instead take the shape of t he container they are fixed in. Solids have! greater density than liquids because the particles are packed more closely together in solids. ?In gases, the particles are much win apart than in solids or liquids, and they are in actually rapid random motion. The particles are so off the crush track(predicate) apart and moving so rapidly that there are no significant forces between them. Because the particles are in such rapid random motion, gases quickly... If you want to get a abundant of the mark essay, order it on our website: BestEssayCheap.com
