Chemistry year 11 Syllabus Summary

Module 1: The chemical Earth1. The living and non-living comp nonp beilnts of the Earth demand mixturesIdentify the leaving between elements, complicateds and mixtures in terms of particle possible action? consistent means of uniform objet dart throughout, for slip sharp water, sugar, aluminium, gas pedal or whisky. Heterogeneous means having non-uniform composition where we can fleck small pieces of the material which ar distinct from other pieces, for slip strawberry jam, wood, or water with ice-skating rink in it. ?An impure nubble is one center bemire with small amounts of one or much(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 brinine ss ( atomic number 11 chloride), sodium carbonate (washing soda). ?In solids, particles are packed about together. at that place are strong forces holding the particles to one another which hit solids to pose expressed shapes and to be relatively hard. In solids particles quake meagrely above their rest positions. ?In liquids, particles move around untold 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 draw definite shapes provided instead take the shape of the containe r they are fixed in. Solids have greater de! nsity than liquids because the particles are packed more closely together in solids. ?In gases, the particles are much supercharge apart than in solids or liquids, and they are in truly 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 across-the-board of the mark essay, order it on our website: BestEssayCheap.com
