Explanation:
Hybridization of 
is 
Bond pair in = 2
lone pair in = 2
Because of presence of two lone pairs of electron shape is bent.
F is more electronegative than O, therefore two O-F bons are polar and hence, two dipole exists. The resultant diople moment in a molecule is the vector sum of individual existing dipoles (shown in the attachment).
because of the bent shape of two dipole moments add to each other. this result in the existence of permanent dipole moment in the molecule and thus is a polar molecule.
It's the number of Protons of that atom..
It would be Microwaves. The cosmic microwave background (CMB, CMBR), in Big Bang cosmology, is electromagnetic radiation as a remnant from an early stage of the universe, also known as "relic radiation".
Answer:
Correct option is D)
Explanation:
Crystallization is the process that is used to separate a pure solid in the form of its crystals from a solution.
Copper sulphate, salt, and potash alum can be purified by this method. In this process, the solution of the substance is heated and then cooled to form crystals.
