When a double bond is placed between two carbon atoms in oelic acid, the shape of the molecule tends to bend. This is a similar occurrence of shape changing in general with fatty acids when a double bond forms
what is the difference between a physical change and a physical property
Burning of (any amount of ) coal is a chemical change.
An alcohol is an organic molecule that contains the hydroxyl (-OH) functional group. Any organic compound whose molecules contains one or more hydroxyl groups is classified as an alcohol.
they change their state by absorbing heat known as latent heat. There is no temperature change in a substance she they change their state because the heat is used to break the intermolecular bonds between the molecule.
A physical change doesn't change the molecule of a compound.
Although the molecule is broken up it does not change the fact that it is carbon dioxide. Therefore you still have carbon dioxide.
what is the difference between a physical change and a physical property
Chemical change: the structure of the molecule is chenged. Physical change: the structure of the molecule is not changed.
Benzene is a nonpolar molecule as well as carbon tetrachloride, however water is a polar molecule. Based on the rules of solubility, "like dissolves like"; the attraction between nonpolar molecules have the same kind of interaction and strength but the attractions between the highly polar molecule of water are very different, therefore substituting these attractions for new attraction with benzene will require a greater change in enthalpy.
A physical change doesn't modify the chemical nature of the molecule.A chemical change transform the molecule A in another molecule B.
For one molecule of Pyruvate (pyruvic acid) the Krebs cycle produces 2 molecules of carbon dioxide (CO2), 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP.Also, the change from pyruvate to acetyl CoA produces one NADH and one carbon dioxide molecule; CoA is recycled in and out of the cycle.
Burning of (any amount of ) coal is a chemical change.
A chemical change involve the molecular modification of reactants.After a physical change the molecule remain unchanged.
When there is less amount of oxygen in muscle cells the Pyruvate (6 carbon molecule) is converted into lactic acid i.e another 3 carbon molecule therefore sudden activities change Pyruvate (6 carbon molecule)to lactic acid causing cramps and strains
The combustion of coal is a chemical change - an exothermic reaction between carbon and oxygen.
Chemical change: the structure of the molecule is modified. Physical change: the structure of the molecule is not modified.
After a physical change the molecule remain intact.After a chemical change the molecule is modified.
