Superscripts in Chemistry Atoms often occur as combinations of isotopes. Hydrogen, the simplest gaseous element, has one electron and one proton in all its atoms. However, a small percentage of hydrogen atoms also have a neutron in the nucleus. This form of hydrogen atom is, naturally, heavier...
Chemistry offers insight into the behavior of molecules. (For its subdiscipline, doing so with a limited range) Organic chemistry compromises between qualitative and quantitative approach, capable of explaining the molecular diversity for evolution of organisms. Chemical biologyapplies the rules of chemistr...

The chapter discusses the achievements that contributed significantly to the advancement of cellulose chemistry. The chemical composition of cellulose (C 6 H 12 O 5 ) n was derived in the middle of the 19 th century. Naturally occurring materials, utilized in the traditional industries, were ...
consider the general form of a line ax + by + c = 0, the slope can be found by converting this form to the slope-intercept form. ax + by + c = 0 ⇒ by = − ax – c or, \(\begin{array}{l}\large \rightarrow y = -\frac{a}{b}x – \frac{c}{b}\end{array}...
This chapter outlines what soft drinks are, describes the various types of products available and sets the scene for later chapters, which deal with the more specialised aspects of the chemistry and technology of these products. There are two basic types of soft drinks: the so-called ready-to...
To solve (find the value of x) an equation in the form, f(x) = 0 Newton's formula for approximations is given by: xapprox= a - f(a) / F(a) where f(x) is the function to be solved and a is a guess at the solution. ...
- Now you know that chemistry is the study of matter... - And small pieces of matter combine to form atoms... - And atoms of different elements can combine to form compounds. - Chemical reactions occur when different compounds combine and create new compounds. ...
