Dissolution overall can be either endothermic or exothermic, depending on whether more energy was used to break the bonds, or more energy was released when new bonds were formed. If more energy is released in making bonds than is used in breaking bonds, the process is exothermic. If more energy is used than is released, the process is endothermic.

What is a special mixture formed when a material dissolves in water?
A special mixture formed when a material dissolves in water is called a solution. In a solution, the material that dissolves is known as the solute, while water is the solvent. The solute particles are dispersed and evenly distributed throughout the solvent, resulting in a homogeneous mixture.
A mixture that forms when one substance dissolves in another is called?
A solution.
Are nonpolar molecules soluble in water?
Nonpolar molecules are generally not soluble in water because water is a polar molecule and like dissolves like.
What is the name of a dangerous substance that dissolves other materials?
A dangerous substance that dissolves other materials is acid. Acid can eat away at most metals and will burn the skin severely.
Could somebody explain the phrase like dissolves like?
This means that substances are more likely to dissolve in other substances with similar chemical properties. It is most often used when discussing polar and nonpolar solvents. For example, oil will not dissolve in water because oil is nonpolar and water is polar. Basically, a polar solvent will generally dissolve polar solutes and sometimes ionic solutes, and a nonpolar solvent will generally dissolve nonpolar solutes.
Why is calcium oxide described as a base?
It reacts with acids, it dissolves exothermically in water to produce a basic solution.
What temp does ammonia dissolve in water?
Ammonia dissolves in water exothermically, with the solubility increasing as the temperature decreases. At room temperature (25°C), ammonia has a solubility of about 32.5 g/L in water.
What will happen to aluminum foil if soaked on Cupric Chloride?
If aluminum foil is soaked in cupric chloride, it will undergo a redox reaction where the aluminum will act as a reducing agent and the cupric chloride as an oxidizing agent. This will result in the dissolution of aluminum and the formation of copper metal on the surface of the foil.
What does 'exothermically' mean?
Exothermic means it gives out heat or energy
What type of substance will react exothermically wit oxygen?
Substances that react exothermically with oxygen include fuels like gasoline, natural gas, and wood. During combustion, these substances release heat and energy as the oxygen in the air supports the chemical reaction.
What dissolves solvent or solute?
The solvent dissolves the solute. (The solute dissolves in the solvent.)
What dissolves the solvent or solute?
The solvent dissolves the solute. (The solute dissolves in the solvent.)
Which compound forms exothermically?
An exothermic reaction releases heat energy to the surroundings. Compounds like combustion reactions (e.g. burning of wood or gasoline) typically release heat during their reaction, making them exothermic.
What must be added to water in order to make the temperature rise?
Either heat, or a chemical that dissolves exothermically. The classic example is sodium hydroxide, which is too dangerous to experiment with. Calcium chloride, which is sold at home improvement stores during cold weather because it'll melt the ice on your sidewalk without taking out the shrubs, is safer and also exothermic...problem is, it's also sold in fifty-pound bags.
What is the substance that dissolves in a solute?
The substance that dissolves is called the "solute" and the substance that the solute dissolves in is called the "solvent".
What is the substance the dissolves in a solution?
The substance that dissolves is called the "solute" and the substance that the solute dissolves in is called the "solvent".
What part of speech is dissolves in the sentence When you put some sugar in water it dissolves?
Dissolves would be the verb.
