Between a water molecule and an anion, like Cl-, a hydrogen bon occurs between hydrogen atom of the water molecule and the anion.

<h3>What is hydrogen bond?</h3>

Hydrogen bond is a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. Hydrogen atom in water molecule attract anion due to presence of hydrogen bond.

So we can conclude that hydrogen bond occurs between hydrogen atom of the water molecule and the anion.

Which of the following statements is incorrect? Group of answer choices The product of wavelength and frequency of electromagnet

morpeh [17]

Answer: Option (b) is the correct.

Explanation:

It is known that energy is directly proportional to frequency.

Mathematically, $E \propto \nu$

or, E = $h \times \nu$ ............ (1)

where, E = energy

h = Plank's constant

$\nu$ = frequency

This relation shows that higher is the energy then more will be the frequency of electrmagnetic radiation.

Also, $\nu = \frac{c}{\lambda}$ ......... (2)

where, c = speed of light

$\lambda$ = wavelength

Therefore, substituting value of $\nu$ from equation (2) into equation (1) as follows.

E = $h \times \nu$

E = $h \times \frac{c}{\lambda}$

This relation shows that higher is the energy then lower will be the wavelength.

Thus, we can conclude that as the energy of a photon increases, its frequency decreases, is incorrect statement.

Svetradugi [14.3K]

Your question looks a bit incomplete as you have the same contents in options a) and d). According to your list, I can't see the correct answer, but I can give you one.The difference between the potential energy of the products of the potential energy of the reactants is equal to the enthalpy of the reaction.
