Watercolor painting demonstrations, advice, and gallery. Painting the sky and clouds with watercolor. Painting the sky and clouds. After doing the drawing our first watercolor painting step is painting the sky and clouds. Create a very weak mixture of French Ultramarine and Burnt Sienna, about the strength of a weak cup of tea.
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have an asymmetric geometry so that the bond dipoles do not cancel each other.
Best Answer: A polar molecule is any molecule that has a charge--thus, it is polarized. For example, water is a polar molecule--this is because the oxygen atom is more electronegative (pulls electrons towards itself) than the two hydrogen atoms.eport Abuse. The arrangement or geometry of the atoms in some molecules is such that one end of the molecule has a positive electrical charge and the other side has a negative charge. If this is the case, the molecule is called a polar molecule, meaning that it has electrical poles.
