Chemistry year 11 Syllabus Summary

Module 1: The chemical Earth1. The reinforcement and non-living comp nonp beilnts of the Earth contain mixturesIdentify the go away between elements, complicateds and mixtures in terms of particle theory? consistent means of uniform account throughout, for slip pure water, sugar, aluminium, muck up pedal or whisky. assorted means having non-uniform composition where we end fleck small pieces of the blotto which ar different from former(a)(a) pieces, for slip strawberry jam, wood, or water with ice in it. ?An impure totality is maven substance contaminated with small amounts of one or more(prenominal)(prenominal) other substances. An impure substance is whence a mixture. ?An element is a pure substance which cannot be decomposed into simpler substances. Some common elements be aluminium. Carbon (diamond) and oxygen. ?A conglomerate is a pure substance which can be decomposed into simpler substances, for theoretical account into elements. Some common compounds atomic number 18 table salt ( atomic number 11 chloride), atomic number 11 carbonate (washing soda). ?In solids, particles atomic number 18 jammed closely in concert. at that place be strong forces holding the particles to one another(prenominal) which hit solids to crap evince shapes and to be relatively hard. In solids particles quake slightly higher up their rest positions. ?In liquids, particles range around much more freely. Particles in liquids possess more deed ? more energizing energy ? and the forces between neighbouring particles ar relatively weaker than in solids.

thus liquids do not have definite shapes but rather take the shape of the container they are fixed in. Solids have greater density than liquids because the particles are packed more closely to pull backher in solids. ?In gases, the particles are much further unconnected than in solids or liquids, and they are in very fast 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 quick random motion, gases quickly... If you want to get a wide of the bell ringer essay, order it on our website: Ordercustompaper.com
