So basically an atom of water or (H2O) is made up of two hydrogen atoms and one oxygen atom that are covalently bonded together to make a compound. A covalent bond is when two nonmetal elements, most commonly, two gases come together to make a compound. So water is a covalent bond because it is hydrogen bonded with oxygen which are both nonmetal elements being bonded together to form a covalent bond. There is a difference between ionic bonds and covalent bonds. The difference between an ionic bond and a covalent bond is that in a covalent bond the two or more elements that are being bonded together share electrons rather than take them like in an ionic compound. So with the fact that covalently bonded compounds share electrons in mind, electrons are not evenly distributed or shared throughout a water molecule because oxygen atoms strongly attract electrons. Because the oxygen atoms do this they pull electrons away from the hydrogen atoms giving them a partial positive charge. Now that the oxygen atom has the electrons closer to it than the other two hydrogen atoms it gives the oxygen atom a partially negative charge. This act of atoms not evenly sharing electrons is called a polar compound. What is special about compounds that are polar is that is attracts both positive and negative ions of an ionic commpund. Thats why water can dissolve ionic compounds because its polar structure.

Some insects can stand on the surface of water because water?
Some insects can stand on the surface of water because water is usually adhesive and cohesive. This is made possible by the molecules in the water.
What chemical and molecular effect does sugar have on water?
Sugar when added to water makes water sweeter.It is harmful for diabetics and helpful to their heirs. Sugar crystals interact with water via hydrogen bonds- weak bonds that take place primarily between positively-charged hydrogen atoms and negatively-charged oxygen atoms. The two substances interact freely when combined. Water molecules surround individual molecules of sugar, breaking the bonds between sugar particles until the crystals are either fully dissolved, or until there are no 'free' water molecules left. When this occurs, the sugar crystals do not fully dissolve. Hydrogen bonds are so weak that they are constantly breaking and reforming, causing individual molecules to exchange positions. Because energy is required to break and form bonds, and heat is a form of energy, the warmer the water, the more readily the sugar dissolves. Water with sugar in it has lower freezing and higher boiling points than pure water.
How can certain bugs walk on water?
explain why certain bugs can walk on water? is because they have webbed feet.
Water is the greatest solute in the world?
I would definitely classify water as the solvent of life. Water is unusually versatile because its polar molecules are attracted to charged and polar substances and the polarity of water molecules result in hydrogen bonding. The four emergent properties of water contribute to the Earth's "fitness for life." the four properties are cohesion, moderation of temperature, insulation of bodies of water by floating ice and being the solvent of life. The ions and polar substances surrounded by water molecules dissolve and are called solutes.
Why does water stick to windows?
Water tends to cling to things because of its chemical properties. The oxygen in water carries a slightly negative charge where as the hydrogen carries slightly positive charges. Because of this, the molecules of water tend to cling together better, creating a high surface tension. It is this surface tension that helps water bead together on objects like glass.
What substance dissolves best in water?
ionic compounds and polar molecules
Does water dissolve ionic compounds because water molecules have a pH value of 14?
Water does not have a pH of 14. By convention water has a pH of 7. Water dissolves ionic compounds because it is a polar liquid.
Why does NaCl dissolve in water?
Water is polar. NaCl is polar. Polar substances are soluble in polar solvents.
What is the difference in the way ionic and covalent compounds dissolve in solutions?
ionic compounds split into individual ions were as covalent compounds dissolves and is surrounded by water molecules
Water dissolves many ionic and molecular compounds why?
because it is a polar molecule
How water disssolves ion compounds and polar compounds?
Like dissolves like. Water is polar solvent and hence it dissolves ionic and polar compounds.
Does water dissolve most things?
Yes. Water is known as a very good solvent mostly because of its ionic structure. Mostly water dissolves ionic compounds because of the like dissolves like.
Discuss how water can dissolve a molecular compond?
Water dissolves some molecular compounds because water is a polar molecule.
Water acts as a solvent of ionic compounds because?
water molecules are polar
Water dissolves many ionic and molecular compounds because of what?
ionic bonding
What happens when sucrose dissolves in 200ml of water?
you just said it === it dissolves. The molecules of sugar are attracted by the water molecules and are separated from other sugar molecules, but they are still sugar molecules.
Does Sugar dissolves in water because the positive ends of the sugar molecules are pulled off the solute surface by the negative ends of the water molecules?
Yes
