    All the objects that exist around us are made up of

    chemical substances. Theseobjects exist an element,

    compound or mixture. All these objects contribute

    benet tohumankind. As time goes on, human has done

    many researches to ensure all thesechemical substances

    will be enough for the use of themselves.Chapter

    of !orm " syllabus introduces the students

    with manufacturedsubstances in industry. This is

    important for the students to appreciate the knowledge

    of chemistry that is still new for themselves. #ersonally,

    $ think that this chapter is aninteresting chapter as it

    revealed the way of scientist produces the material

    around me. $talso gives me new knowledges of the uses

    of chemical substances that $ usually found inthe

    laboratories.$ hope, by learning this chapter, $ will be

    more interested in learning chemistry asit will help me

    in the future. All the e%uations from this chapter make

    me moreunderstand of the previous chapters

    We must appreciate these various synthetic industrial materials. One of

    the way is bydoing continuous research and development ( R & D ) to

    produce better materials used toimprove our standard of living. As we

    live in a changing world our society is getting more comple!. "ew

    materials are re#uired to overcome new challenges and problems weface

    in our daily lives. $ynthetic material are developed constantly due to the

    limitationand shortage of natural materials. "ew technological

    developments are used by scientiststo ma%e new discoveries. "ew

    materials for clothing shelter tools and communication to improve our

    dailylife are developed continuously for the wellbeing of man%ind. "ew

    needs and new problem will stimulate the development of new synthetic

    materials. 'or e!ample the newuse of plastic composite material will

    replace metal in the ma%ing of a stronger andlighter car body. his will

    save fuel and improve speed. lastic composite materials mayone day

    used to ma%e organs for organ transplant in human bodies. his will

    becomenecessity with the shortage of human organ donors.he

    understanding of the interaction between different chemicals is important

    for both the development of new synthetic materials and the disposal of

    such syntheticmaterials as waste. A responsible and systemic method of

    handling the waste of syntheticmaterials and their byproduct is

    important to prevent environmental pollution. herecycling and

    development of environmental friendly synthetic material shouldbeenforced
