When you fire clay, the clay has to be in a kiln at a very high temperature. Clay is made up of about 25% water. At about 660 degrees fahrenheit in the kiln, the water in the chemical make up of the clay goes away, changing the chemical make up of clay. This is one of the chemical reactions that take place in the firing process of clay. At this point, you can no longer mix it with water the get wet clay. This process is called dehydration.

When iron and oxygen meet, it forms rust. The iron found in metal oxidizes and combines with the oxygen molecules found in the air. When they combine, they form rust, which cannot be turned back into iron or oxygen, which is why this is a chemical reaction.

When you cook eggs, it produces an aroma that you can smell throughout the house. When you apply heat to eggs, the egg white proteins bounce around. When they bounce around, they collide with other water molecules. When they collide with the water molecules, the proteins uncurl. Then, new chemical bonds form, connecting one protein to another protein. The water is held in the web of proteins that connect to each other. If you keep the egg in a high temperature too long, too many bonds form and the egg becomes rubbery.

The basic idea of Luminol is to find traces of blood in the carpet or on walls. Luminol had chemicals that produce light when reacted with blood. This makes it very easy to find traces of blood that have been cleaned over time. The atoms in Luminol and in the blood rearrange to form different molecules. The reactants have more energy than the products. The molecules get rid of the extra energy in the form of visible light. This is called chemiluminescence, the same process that makes fireflies and glowsticks glow.

Glow sticks produce a glow by using a chemical reaction that produces light. The reaction between the two chemicals causes a large release of energy. The electrons go to a higher level of energy, and when they return to their normal energy level, they produce light photons. Like Luminol, this process is called chemiluminescence. The different colors are produced by the different chemical make ups of the fluorescent dye in the glow stick.

In this exothermic reaction, the amount of energy gained is greater than the amount of energy put into the reaction. The spark is needed to produce the energy and break the Carbon-Carbon and Carbon-Hydrogen bonds in the hydrocarbon molecule and the Oxygen-Oxygen bond in the oxygen molecule. The energy is released when new bonds form. Water and carbon dioxide form and both release energy. The carbon dioxide bonds release much more energy than the water bonds, and release energy in the form of heat.

The liquid inside the pack is water, and inside the bag is another bag containing ammonium nitrate. When you shake the pack, it breaks the tube between the bags so the water mixes with the ammonium nitrate fertilizer. This is an endothermic reaction, which means that it absorbs heat. The temperature drops to a very low temperature for about ten to fifteen minutes.

Mixing an Acid with a Base - New substance formed

# data[].attributes.body
When an acid and a base are combined, they neutralize the acid and base properties, producing a salt. The compound formed by the cation of the base and the anion of the acid is called a salt. For example, the chemical combination of hydrochloric acid and sodium hydroxide produces water and table salt.

The vinegar, which is also called acetic acid, reacts with sodium bicarbonate, which is the baking soda and also a base, and this reaction produces carbon dioxide. The carbon dioxide is given off as a gas, which causes the fizzing and bubbling.

Whenever you smell something burning with smoke, there is a chemical reaction. When you burn paper, this is a chemical reaction because it turns into ash, and you cannot get the paper back to its original state. To burn, the paper must be oxidized, and the bonds that made the paper are broken.

When you are making a cake, it produces a very sweet smell, which is an indicator that there is a chemical reaction. ou make the batter with water, flour, yeast, sugar, salt, and baking soda. When you add heat, or put the batter in the oven, the cake rises. This is a chemical reaction because you can no longer see the batter. The baking soda in the cake becomes sodium carbonate, water, and carbon dioxide, which make the cake have the little holes in it. The proteins also react with each other.

Alka seltzer is used mostly to clean clothes and other products. Alka seltzer is made up of citric acid, and sodium bicarbonate, which is also known as baking soda. When the acid and the baking soda react with each other, this produces a fizz.

In this chemical reaction, the coke explodes because of a process called nucleation. The carbon dioxide in the soda is attracted to the mentos, and this creates a lot of pressure. All of the fizz is packed into the liquid and it is looking for a way to come out. It is drawn to the tiny bumps that are on the mentos. The tiny bumps are called nucleation sites. The coke can grab onto the nucleation sites and start forming bubbles.
