What is the name the property of water in which it sticks to other substances?
The attraction between water molecules and another substance is called adhesion. An example of this phenomenon is the absorption of water by a towel. Water molecules are also attracted to each other by cohesion. Adhesion and cohesion of water are both caused by the polarity of water molecules. Molecules are said to be polar if they have opposite electrical charges at different ends of the molecule. Nonpolar molecules have none or evenly distributed charges (oil is an example of a nonpolar substance). Since opposite charges attract, water is attracted to other polar (or ionic) substances.

Can polar covalent molecules dissolve in water?
Yes, polar covalent molecules can dissolve in water because water is a polar solvent. The partial positive and negative charges on polar covalent molecules interact with the partial charges on water molecules through electrostatic forces, allowing them to be surrounded and dissolved in water.
What is occur when salt is evenly mixed with water?
When salt is evenly mixed with water, it dissolves into the water forming a homogeneous solution. This happens because the salt molecules interact with the water molecules, breaking apart into ions that are uniformly distributed throughout the water.
What causes sugar to disperse evenly in water?
When sugar is added to water, the water molecules surround the sugar molecules and disrupt the attractive forces between sugar molecules, causing them to separate and disperse evenly throughout the water. This process is known as dissolution or dissolving, and it occurs because water is a polar molecule that can interact with the polar sugar molecules.
What molecules would you expect to dissolve in water polar covalent molecules ionic molecules nonpolar covalent molecules?
Polar covalent molecules are likely to dissolve in water because they have partial positive and negative charges that can interact with water molecules through dipole-dipole interactions. Ionic molecules also dissolve in water as the positive and negative ions are attracted to the polar water molecules. Nonpolar covalent molecules do not dissolve well in water because they lack partial charges that can interact with water molecules.
Hydrophilic molecules readily associate with?
Water molecules due to their ability to form hydrogen bonds with the polar water molecules, making them soluble in water. This interaction allows hydrophilic molecules to be evenly dispersed throughout the water.
Describe as a series of steps what happens to sugar molecules when they dissolve in water?
When sugar molecules dissolve in water, they are surrounded by water molecules that bond with them. This process breaks the sugar molecules apart, dispersing them evenly throughout the water. As a result, a sugar solution is formed where individual sugar molecules are no longer distinguishable.
Why does oxygen in a water molecules have negative charges?
Oxygen is an anion.
Give one reason why water molecules are attracted o each other?
The H atoms with partial + charges attract O atoms with partial - charges on other water molecules.
Why are polar covalently bonded molecules soluble in water and non polar are not?
Water is a polar covalent molecule. The partial charges in the molecule attract other charges, ionic or more partial charges from other covalent molecules and dissolves them. Nonpolar bonded molecules have no partial charges and the water molecules will attract each other thus not attracting the nonpolar and does not dissolve them.
How do polar molecules dissolve in water?
Dissolving is just when water bonds and separates the cation and anion. Water's polarity is the reason why it surrounds each ion and separates it from the oppositely charged ion thus dissolving it. The negative end of the water surround the positive ion and the positively charged end of water surround the negative ion. If there is a polar molecule it will bond in a network with the polar water molecules This is why water will not dissolve non-polar molecules because the polarity has no affect on a non-polar molecule.
