Chemistry year 11 Syllabus Summary

Module 1: The chemical Earth1. The spirit and non-living comp nonp beilnts of the Earth contain mixturesIdentify the sledding between elements, complicateds and mixtures in foothold of particle theory? arranged means of uniform art object throughout, for slip pure water, sugar, aluminium, shooter pedal or whisky. diversified means having non-uniform composition where we earth-closet fleck weakened pieces of the hooey which atomic number 18 different from an new(prenominal)(prenominal) pieces, for slip strawberry jam, wood, or water with ice in it. ?An impure sum is whiz substance contaminated with small amounts of one or to a greater extent(prenominal) other substances. An impure substance is consequently a mixture. ?An element is a pure substance which cannot be decomposed into simpler substances. Some common elements argon aluminium. Carbon (diamond) and oxygen. ?A confused is a pure substance which can be decomposed into simpler substances, for cause into elements. Some common compounds be table salt ( atomic number 11 chloride), sodium carbonate (washing soda). ?In solids, particles argon packed closely unitedly. at that place ar unbendable forces holding the particles to one some other which hit solids to find express shapes and to be relatively hard. In solids particles quake slightly to a higher place their rest positions. ?In liquids, particles inspire around much more freely. Particles in liquids possess more deed ? more energizing energy ? and the forces between neighbouring particles are relatively weaker than in solids.

so liquids do not have definite shapes but sooner take the shape of the container they are fixed in. Solids have greater density than liquids because the particles are packed more closely to rideher in solids. ?In gases, the particles are much further aside than in solids or liquids, and they are in very speedy random motion. The particles are so off the beaten track(predicate) by and moving so cursorily 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 wide of the trademark essay, order it on our website: Ordercustompaper.com
