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

daughter isotopes Metamorphism must not have taken place causing resetting of the radiometric clock The ratio of the two isotopes is constant in a living organism. When the organism dies the Carbon 14 is not replenished so the ratio of carbon 12 to carbon-14 gradually increases However the half life of carbon-14 is 5730 years and so is useful for up to about 50‚000 years old. Beyond this levels of it are so small that errors and so large as to make the measurements too uncertain. Interstellar gas

How a faster pulse rate after exercise affects the amount of carbon dioxide in breath and how males and females pulse rates change or don’t after exercise Introduction There is a chemical reaction that takes place in this lab‚ O2 + C6H12O6 –> H2O + CO2 + ATP. This represents cellular respiration‚ the reaction. The reactants are Oxygen and Glucose. The products are water‚ carbon dioxide‚ and ATP. This reaction is split into 3 stages‚ the Glycolysis stage‚ the Krebs cycle‚ and the Electron Transport

Their oxides undergo reduction by heating with H2‚ carbon‚ and carbon monoxide. * The metals lithium - copper‚ can combine directly with oxygen to form the oxide. * The last five metals (mercury - gold) are often found free in

COAL Coal is made up of carbon‚ oxygen‚ hydrogen‚ nitrogen and some amounts of sulphur -Three main types of coal: • Anthracite : the hardest and has the most carbon in it‚ meaning higher energy content • Lignite: softest‚ low in carbon‚ but high in oxygen & hydrogen • Bituminous: All of the above found in similar amounts Coal is mined out of the ground using various methods
