Even individual proteins are some of the most complicated molecules known to man, not to mention a whole conglomeration of different ones. Things like skin, wood, milk, blood, dirt, etc are very complicated mixtures of things.

Once these molecules escape from the burning piece of wood and encounter oxygen, but as the piece of wood gets hotter and volatile compounds are released faster, the oxygen immediately around the ...


Does wood have moving molecules? Yes it does - molecules move in all substances. The motion depends on the nature of the substance (solid, liquid or gas) at a particular temperature and pressure. Wood is solid and the molecules are strongly cross-linked to each other so at room temperature and normal pressure, they do not move very much.


When wood burns, oxygen and sugar molecules disappear, and they are replaced by carbon dioxide and water molecules. Molecules are not conserved in chemical reactions. However, the same atoms that make up the reactant molecules form the product molecules. Thus, atoms are rearranged in different molecules.


It is apparent, however, that one Oxygen molecule is not sufficient to burn one Methane molecule. Methane contains 5 atoms (1 C and 4 H). The C atom needs 2 O atoms to form one CO 2 molecule. A couple of H atoms needs one O atom to form one H 2 O molecule, and there are two such couples. Summing up, the methane molecule requires 4 O atoms, that are found in 2 oxygen O 2 molecules.


Seeds, roots, stems (wood and bark of woody plants): storage of calories and N 3. Enzymes catalysts: speed up chemical reactions but are not consumed or changed by the reaction As enzymes, proteins are responsible for all metabolic reactions and the synthesis of all of the other molecules found in organisms (pigments, hormones, etc.)


Energy stored in chemical bonds of molecules is referred to as chemical energy. This is known as 'enthalpy'. The type of energy that is stored in a molecules bonds is potential energy.


Ok….. Atoms make up everything. In the case of the wooden table. * The atoms make up the elements * These elements come together to make up molecules * These ...


a. Ozone molecules absorb only low energy infrared frequencies b. Ozone molecules have a low molecular weight c. tropospheric ozone concentrations are not changed by human activity d. ozone has a relatively short lifetime in the troposphere and its distribution is not uniform around the world
