4、chemistry-there would be no plastics,no electricity and no protective paints for our homes.There would be no synthetic fibres to clothe us and no fertilisers to help us produce enough food.We wouldnt be able to travel because there would be no metal,rubber or fuel for cars,ships and aeroplane.Our li
5、ves would be changed considerably without telephones,radio,television or computers,all of which depend on chemistry for the manufacture of their parts.Life expectancy would be much lower,too,as there would be no drugs to fight disease.2 The first and second laws of thermodynamics and the meaning of
6、entropy will be discussed.and expanded upon in this lesson.It will be shown that energy transformations on a macroscopic scale that is,between large aggregates of atoms and/or molecules can be understood in terms of a set of logical principles.Thus thermodynamics provides a model of the behavior of
7、matter in bulk.The power of such a model is that it does not depend on atomic or molecular structure.Furthermore,conclusions about a given process.based on this model,do not require details of how the process is carried out.酸根二甲基戊烷三甲基乙基辛烷石蕊试纸滴定非电解质配位化合物二把下列句子译成英文本题共分每小题分包括所有消亡即宇宙中的能量是守恒的当酸的当量等于碱的当量时
