Answer: option B, Dipole-Dipole forces
Explanation:
By VESPER theory, shape of H2S is bent and Central atom Sulfur has two lone pair of electrons. Because of asymmetrical shape ,H2S is polar molecule.
Due to polar nature it has strong dipole-dipole intermolecular forces
Answer:
As a general rule, soluble ionic compounds, strong acids, and strong bases should be written as dissociated ions in the complete ionic equation. Insoluble salts and weak acids are written using the neutral molecular formula since they only dissociate to a very small extent in water.
Explanation:
Answer:
c. To facilitate a reaction of one substrate to form two products without the use of water
Explanation:
A lyase is an enzyme that catalyzes - accelerates the chemical reaction - in which a substrate is broken into two molecules. The reaction does not involve hydrolysis or oxidation, so the water molecule is not included in the chemical reaction. Thus, the enzyme facilitates the reaction in which a molecule (substrate) is decomposed into two molecules with the elimination of chemical bonds.
They break down amino acids to digest the food you've eaten
Explanation:
Generally in normal phase column, inside the column silica gel present is in normal phase and it strongly reacts or combine with more polar ferrocene compounds. Whereas, less polar ferrocene compounds weakly interact with this silica gel.
Hence, on starting with least polar solvent or solvent-mixture the less polar ferrocene compounds will tend to elute first of all because these will weakly interact with the silica gel. Therefore, readily able to move away from the gel.
On increasing the polarity of solvent or solvent mixture, more polar ferrocene compounds will start to elute first. As a result, on changing the solvent polarity we can (from least to more polar) it is possible to get pure products.
But if we start with more polar solvent at first then almost all of the ferrocene compounds will elute leading to poor separation from the column due to which you will end up having a mixture of ferrocene compounds.
