How does the polarity of water molecules make water an effective solvent?
The polarity of the water molecule is what makes water a great solvent. It called the universal solvent.
How does a water molecules polarity affect its usefulness to living things?
Water's polarity lets it stay liquid at room temperature. Most molecules of water's size are gas, but because water molecules attract each other they are connected by polar bonds that cause it to be liquid. Also, its polarity make it a solvent. Molecules connected ionically get separated when introduced into water. This is why salt disolves in water, literally because the water breaks up the ionic bond between the Sodium and Chloride. Also, water's ionic nature is what lets it move up the roots and stems of plants and into the leaves. This process is similar to how if you place the edge of a paper towel in water the water moves up the paper towel inspite of gravity.
How can the degree of polarity be predicted?
The strength of polarity can be determined from looking at the level of polarity an object has. Polar bonds can make objects stronger or weaker.
What properties of water make it a good solvent?
Water has extremely high polarity, making it an effective solvent for ionic and polar materials. It is non toxic and easy to dispose of. It does not have toxic fumes. It is cheap to obtain ( in some forms and compared to other solvents ).
Why do you want soft water for washing clothes?
softwater doesn't contains salts ...it can make bond with fists so soft water is preferable
How does a drawing of polarity water and the bond polarities make a major contribution to the overall molecular polarity look?
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
How does electronegative affect the polarity the polarity of the bond between two atoms?
The more electronegative atom will make its end of the bond more negative.-Apex
Why do sodium and chlorine make ionic bonds?
because the bond between them have greater polarity than that of a covalent bond.
Why chlorine is not included to make hydrogen bond?
As fluorine, oxygen and nitrogen do, the bond polarity in a -H-Cl bond is not adequate to form hydrogen bonds.
Why is melting point of ammonia lower than water?
The melting point of a substance is based upon the polarity of the bonds that make up the substance. In water, the O-H bond has a difference in electronegativity of 1.4 (Pauling's Scale) and in ammonia, the N-H bond has a difference in electronegativity of .9. Therefore, it takes more energy to break apart the O-H bond because the polarity is so great, and this is why it has a higher melting point than ammonia.
How does the polarity of water molecules make water an effective solvent?

What can reverse magnetic polarity make?
What can reverse magnetic polarity
What atoms make water?
2 hydrogen bond and 1 oxygen bond H2O
How is the cell membrane selectively permeable?
The pores of the cell membrane only allow objects of a certain size or polarity through. The lipids that make up the membrane have a certain polarity at the head and tail and only certain objects are allowed through because of this.

What atomic or hybrid orbital on O makes up the sigma bond between O and H in water H2O?
Oxygen atoms in water form sp3 hybridized orbitals. This configuration of bond angles and bond lengths between the electron pairs and hydrogen atoms on oxygen allow for the least strain.

The strength of polarity can be determined from looking at the level of polarity an object has. Polar bonds can make objects stronger or weaker.
