Students will make a 2-D model of a salt crystal and use water molecule cut-outs to show how water dissolves salt. After seeing an animation of water dissolving.
No. The SUBSTANCE is still water, only now sugar is dissolved in it.
Yes, the apparent shape of sugar changes when dissolved in water. Sugar in its solid, crystallized form is a cube. When dissolved in water, the individual molecules separate, and the crystalline structure breaks down.
Substances with nonpolar molecules are not dissolved in water.
When salt is dissolved in water, it is in a dissolved state where the salt particles break apart into ions. This creates a solution where the salt ions are surrounded by water molecules.
If it can be dissolved in water, it will have a charge because it will form freely moving ions, so basically, all molecules that are soluble in water will form freely moving ions, which are charged

because the salt molecules have mixed up with the water molecules
When salt is dissolved in water, it forms a solution where the salt molecules are evenly dispersed throughout the water molecules. This is a physical change as the salt and water molecules remain the same, only their arrangement has changed.
Substances with nonpolar molecules are not dissolved in water.
In the case of oxygen dissolved in water, oxygen is the solute and water is the solvent. Oxygen molecules are dispersed (dissolved) in water, which acts as the medium in which the oxygen molecules are distributed uniformly.
No, sand is not dissolved in water because sand has larger molecules than water molecules.
The molecules of a dissolved substance are surrounded by water molecules and are not visible as separate substances.
Water dissolved compounds are substances that have been fully dissolved in water, forming a homogeneous mixture known as a solution. These compounds can be inorganic salts, such as sodium chloride, or organic molecules, such as sugar. The solubility of a compound in water depends on its chemical structure and the interactions between its molecules and water molecules.
Sugar and water both are ionic compounds. Due to this sugar dissolve into water further sugar molecules breaks into small molecules in presence of water molecules.
It is made of water (H2O) molecules and salt (NaCl) molecules. So two different types of molecules.
Releasing free electrons is how dissolved particles in water affect the movement of water molecules.
