I have a chemistry task today it should be very simple to anyone with chemistry knowledge it is around 5 questions no work needs to be shown only answers. time is crucial for this task.a branch of science that involves the study of the composition, structure and properties of matter. Often known as the central science, it is a creative discipline chiefly concerned with atomic and molecular structure and its changehave been identify as elements. Although these atoms, in turn, are compose of more elementary particles,
they are the basic building blocks of chemical substances; there is no quantityThe great challenge in chemistry is the development of a coherent explanation of the complex behaviour of materials, why they appear as they do, what gives them their enduring properties, and how interactions among different substances can bring about the formation of new substances and the destruction of old ones. contains millions of atoms. New substances can even be design to bear desired characteristics and then synthesized. The rate at which chemical knowledge continues to accumulate is remarkable. Over time more than 8,000,000 different chemical substances,
both natural and artificial, have been characterize and produce. The number was less than 500,000 as recently as 1965. From the earliest attempts to understand the material world in rational terms. Chemists have struggled to develop theories of matter that satisfactorily. This is to explain both permanence and change. The ordered assembly of indestructible atoms
