A bond between two atoms is polar if the electrons of the bond are unevenly distributed. If the bond is polar enough the possibility exists for one atom to take both electrons. If it does that the bond breaks and it is said to have 'dissociated'. In general, solvents are referred to as polar and non-polar. Water (H2O) is a polar solvent while Acetone (Propanone) is a non-polar solvent. Water will dissolve ionic species such as salts, while Acetone will dissolve covalent (non-ionising) compounds.
polar compounds differ from non polar in the properties of bonding.polar compounds dissociate into ionsand they have the property of hydrogen and other bonding properties where as non polar lose this property .their melting points are high because of their bonding nature they are freely soluble maximum in all solvents.bothof the differences are highly eluted in chromatography
Solids - Bonds between molecules are strong, holding a constant form with a definite mass. Liquids - Bonds between molecules are not as strong, still have a definite mass due to their temperature and take the form of the container. Gases - Molecules float freely with and are impossible to get a definite mass or volume on an open sample.
How does ethnography differ from ethnology?
Mass is just "the amount of stuff there is". We can measure it in kg. If I have 4kg ice and 4kg water, then the answer is "no", but I could just as easily have 4kg of ice and 5kg water, in which case the answer is "yes". If you mean "does freezing water make it heavier?", then the answer is no - 4kg water makes 4kg ice, and they will weigh the same. However, ice has a greater volume than water*, so freezing water will make it expand. *This is not true for every liquid/solid combo.
The molecular formula, C3H6O, obviously does not show the difference between the isomers. You can draw a full structural formula for each of them, but we also can simply group the atoms to show their positions, viz CH3COCH3 for acetone and C2H5CHO for propionaldehyde.
Well chemistry is the study of chemicals and elements molecules and such and how they react with each other and what they do biology is the study of life and climate science is the study of weather paterns and well climate of certain regions?
oxygen
oxygen
No. It is polar.
Technically all H2O molecules are polar.
It is polar, not polor.
nonpolor
differ from what?
The slightly negative end of one polar molecule will be attracted to the slightly positive, hydrogen end of another molecule.
because,acording to their structure they differ.
ADP have two phosphate molecules and ATP have three phosphate molecules in it.
Yes
they differ from their molecules when gas molecules have lots of energy ,liquid has less energy, and gas has the smallest amount of energy.
