When you heat chocolate, the cocoa butter crystals melt and the chocolate becomes fluid, but if you get the chocolate too hot, it can separate into burned, blackened cocoa particles and pale golden liquid. It contains small amounts of fats that do not melt until high temperatures--over 200°F/93 °C.

What are chemical changes and chemical reactions?

A chemical change, also known as a chemical reaction, is a process in which one or more substances are altered into one or more new and different substances. In other words, a chemical change is a chemical reaction involving the rearrangement of atoms.

Is chocolate a crystal?

You may be surprised to learn that chocolate, that delightful confection, is a crystal, too. Crystals are solids whose molecules, atoms, or ions are connected to one another in an organized pattern—called a crystalline structure—that repeats over and over throughout the solid.

How many crystal structures does chocolate have?

sixCocoa butter has at least six different structures, or 'crystal forms', the ability of a substance to display different structures is known as 'polymorphism'. These crystal structures differ in how the molecules are arranged, which in turn influences their properties, such as appearance, taste, and texture.

Is a firework a chemical change?

Fireworks are the result of chemical reactions involving a few key components -- like a fuel source (often charcoal-based black powder), an oxidizer (compounds like nitrates, chlorates that produce oxygen) and a color-producing chemical mixture. The oxidizer breaks down the chemical bonds in the fuel, releasing energy.
