Answer:
B. It shows the ratio of elements in the compound.
Explanation:
Empirical formula tells about the ration of the elements found in the compound . The ratio are in complete number .
For example the molecular formula of glucose is C₆ H₁₂O₆
Its empirical formula = CH₂O
When using filter paper chromatography to separate ink, one will observe that more colours are mixed into darker inks. The darker an ink is, the more the colours that will be separated out during chromatography process. Thus, the observation that the darker the ink, the more colours are mixed into it will lead one to believe that ink is a mixture.
Answer :
Dipole moments occur when there is a separation of charge. Dipole moments occur due to atoms electronegativity, where one atom has the ability to attract electrons towards it giving it a negative charge and the one deficient in electrons acquire a positive charge called as the bond moment.
But if the bond moments are equal and opposite in direction , they cancel each other and thus there is no net dipole moment in the molecule.
For example: In carbon dioxide , both the -C=O bonds are polar but as the molecule is linear and the the magnetic moments are equal and oppposite, they cancel each other and the molecule is non polar.
