When placed between oppositely charged metal plates, the region of a water molecule attracted to the negative plate is the *blank*a) hydrogen region of the molecule b) geometric center of the molecule c) h-o-h plane of the molecule d) oxygen region of the molecule

Answer : The correct option is (A) Hydrogen region of the molecule.

Explanation :

As we know that the water molecule has two hydrogen atom and one oxygen atom. The hydrogen atom has partial positive charge and oxygen has partial negative charge.

In the charged plate, the negative attracts positive and positive attracts negative. So, the hydrogen atom attracted to the negative plate and the oxygen atom attracted to the positive plate.

When water molecule placed between oppositely charged metal plates which is positively charged, then the hydrogen atom which is positively charged attracted towards the negative plate.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
