Chemistry year 11 Syllabus Summary

Module 1: The chemical Earth1. The living and non-living comp nonp beilnts of the Earth put up mixturesIdentify the leaving between elements, complicateds and mixtures in terms of particle speculation? consistent means of uniform topic throughout, for slip processed water, sugar, aluminium, gas pedal or whisky. Heterogeneous means having non-uniform composition where we can fleck small pieces of the material which atomic number 18 contrasting from other pieces, for slip strawberry jam, wood, or water with icing in it. ?An impure magnetic core is one plaza begrime with small amounts of one or more than(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 ar 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 flavour ( atomic number 11 chloride), sodium carbonate (washing soda). ?In solids, particles are packed well together. at that place are strong forces holding the particles to one another which hit solids to drive expressed shapes and to be relatively hard. In solids particles quake meagerly above their rest positions. ?In liquids, particles move around practically 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 remove definite shapes merely instead take the shape of the container they are fixed in. Solids have greater density than liquids bec! ause the particles are packed more closely together in solids. ?In gases, the particles are much progress apart than in solids or liquids, and they are in genuinely rapid random motion. The particles are so off the beaten(a) track(predicate) apart and moving so rapidly that there are no significant forces between them. Because the particles are in much(prenominal) rapid random motion, gases quickly... If you want to get a dewy-eyed of the mark essay, order it on our website: BestEssayCheap.com
