What is the quantity of oxygen required for complete combustion of 1 mole of an organic compound CxHyOz
Answers
There are many reasons to examine human cells and tissues under the microscope. Medical and biological research is under-pinned by knowledge of the normal structure and function of cells and tissues and the organs and structures that they make up. In the normal healthy state the cells and other tissue elements are arranged in regular recognizable patterns. Changes induced by a wide range of chemical and physical influences are reflected by alterations in structure at a microscopic level and many diseases are characterized by typical structural and chemical abnormalities that differ from the normal state. Identifying these changes and linking them to particular diseases is the basis of histopathology and cytopathology, important specializations of modern medicine. Microscopy plays an important part in haematology (the study of blood), microbiology (the study of microorganisms including parasites and viruses), and more broadly in the areas of biology, zoology and botany. In all these disciplines specimens are examined under a microscope.
The amount of O₂ needed for complete combustion of 1 mole of CxHyOz will be [x +y/4-z/2] moles
- The equation for the combustion of hydrocarbon is as follows:
CHO + O₂⇒ CO₂ + H₂O
- In the given question, the hydrocarbon that undergoes combustion has the formula CxHyOz. The equation for its combustion will be:
CxHyOz + [x +y/4-z/2]O₂⇒ xCO₂ + (y/2)H₂O
- It is the general equation for the combustion of a hydrocarbon with a given formula CxHyOz which results in the formation of x moles of CO₂, y/2 moles of H₂O, with the consumption of [x +y/4-z/2] moles of O₂.
Thus, [x +y/4-z/2] moles of oxygen is required for the complete combustion of 1 mole of an organic compound CxHyOz.
