INTRODUCTION From natural gas‚ crude oils‚ and other fossil materials such as coal‚ few intermediates are produced that are not hydrocarbon compounds. The important intermediates discussed here are hydrogen‚ sulfur‚ carbon black‚ and synthesis gas. Synthesis gas consists of a nonhydrocarbon mixture (H2‚CO) obtain- able from more than one source. It is included in this chapter and is fur- ther noted in Chapter 5 in relation to methane as a major feedstock for this mixture. This chapter discusses

• Legibility Counters: open and wide. x-height: high (61%)‚ especially for a serif typeface. Width and weight: Compared with other serif typefaces‚ Garamond is relatively a narrow (103%) and light (18%‚ 7%) type‚ which likely contributes to its being so eco-friendly when printed. The result is that it fit more letters on a page and the page will still look light. Distinctions: the original Garamond was created using a brush‚ and this is apparent in letterforms. It is easy to see there is a great

"In mineralogy‚ diamond (from the ancient Greek αδάμας – adámas "unbreakable") is an allotrope of carbon‚ where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is renowned as a material with superlative physical qualities‚ most of which originate from the strong covalent bonding between its atoms. In particular‚ diamond has the highest hardness and thermal conductivity of any bulk material. ELECTRICAL CONDUCTANCE: - . Diamond
