Conventions in chemistry

We examine all three formats in this chapter, but before we do, we note an important writing convention in chemistry in general, authors are not referred to by name in the actual sentences that describe their work. Consider the following examples, illustrated with the superscript number and author-date formats ... 

Other points of style are discussed in Chapter 11, Numbers, Mathematics, and Units of Measure Chapter 12, Names and Numbers for Chemical Compounds and Chapter 13, Conventions in Chemistry . 

Chapter 11 describes the use of italic type in mathematical material, and Chapters 12 and 13 give guidelines for the use of italic type in chemical names and conventions in chemistry. 

Noie the convention in chemistry that 48 g of ozone" is singular i number it means a quantity of ozone weighing 48 g, rather than forty-eight separate grams of bzonf. 

Compartmentalisation of physical science subjects, viz. the presentation of chemistry and physics as unrelated disciplines, the use of inconsistent terminologies in chemistry and physics, and the use of different conventions in chemistry and physics. These characteristics imply the need for enhancing the coimecfion and the consistency between concepts from chemistry and physics. 

Students often have difficulty with 1—J sign conventions in chemistry. By convention, differences of energies in chemistry (AH, A , etc.) are always the value at the final state minus the value at the initial state. This is necessary for the arithmetic sign of the result to be correct.
