Chemical Energy

Chemical energy is a form of potential energy, and is present in various things such as foods, fuels and batteries. It may be released during a chemical reaction, often in the form of heat.

Is chemical energy a form of energy?

Yes, chemical energy is a form of potential energy. An example is the chemical energy in coal, which can be burned to convert that chemical energy into thermal energy.

List and describe 3 fossil fuels?

Coal, natural gas, and oil are all examples of fossil fuels. Coal was formed in the warm tropical swamps that were located near the equator. It must be mined, that is the only way to get to it. Natural gas was formed by bacteria partially decomposed the organic materials mixed with sediment. This released methane gas as a waste product. This gas makes up part of the natural gas we use for energy. Oil was formed in a similar way. Millions of years ago earth was covered with shallow seas. Rivers carried sediments into these seas. Organisms that died were also washed into the seas as part of the sediment. Scientists believe that oil formed from those decayed plants and animals.

What is the energy in gasoline called?

Thermochemical, as energy is released by the the chemical reactions between air and gasoline due to an igniting catalyst or heating (which may occur in different ways)

What is the partial molar free energy?

Partial molar free energy is the thermodynamic quantity, which indicates how the properties of a mixture vary with changes to their molecular composition, when being kept at a constant temperature and pressure.

Is there proof that antimatter exist?

yes, positrons were discovered in experiments in the 1930s just like theory had predicted. many other anti-particles have been discovered since.

What does thermal energy convert to?

Thermal energy is just heat. To convert it to mechanical energy you need some sort of heat engine, like an internal combustion engine or a gas turbine.

Is firework a chemical reactions?


Yes, the gunpowder reacts with oxygen. The oxygen comes from oxidizers perchlorates, chlorates, nitrates, permanganates, chromates or oxides.

In propelling the rocket, potassium nitrate is used with black powder. Chlorates or perchlorates are used for the explosion as it reacts with carbon and sulfur rapidly. For the different colours of firework, various metal salts are used.

What is chemical energy and how is energy formed?

Chemical energy is produced through reactions that occur in chemical compounds. A chemical compound is a simple collection of many atoms that are bound to each other. As the bonds between these atoms loosens or breaks, a chemical reaction will occur, and new compounds are created. When the bonds break or loosen, oxidation occurs almost instantly.

Do nonmetals gain electrons to form positively charged ions?

You are only half right. Nonmetals do indeed gain electrons when they undergo chemical reactions, but this does not cause them to form positively charged ions. Remember that electrons have a negative charge! So if an atom gains electrons, it forms a negatively charged ion.

Bunsen Burners

What is a Bunsen burner and how is it used?

From Wikipedia (see Link to the left):

A Bunsen burner is a device used in scientific laboratories for heating, sterilization, and many other uses.

The device safely burns a continuous stream of a flammable gas such as natural gas (which is principally methane) or a liquified petroleum gas such as propane, butane, or a mixture of both.

From ScienceByJones.com (see Link to the left):

The Bunsen burner is used frequently in the laboratory as a source of heat. This burner is designed so that gaseous fuel may be mixed with the correct amount of air to yield the maximum amount of heat. In order to use this burner properly and safely, it is essential that you understand its construction and the adjustments that can be made.

The three principal parts of the burner are: barrel, needle valve, and base. The quantity of gas admitted to the burner is controlled by the needle valve, while the air needed for combustion is admitted at the small opening around the bottom of the barrel. The air is controlled by turning the barrel so as to make the air holes larger or smaller.

Always open the desk outlet valve fully and regulate the gas supply to the burner by the needle valve. Always extinguish your burner by turning off the desk outlet valve (and then closing the needle valve and barrel.) If there is an accident always shut off the desk outlet valve immediately.

STEPS TO LIGHT BUNSEN BURNER:

1. Check connections to burner and desk outlet valve.

2. Close needle valve and barrel.

3. Open desk outlet valve fully.

4. Check for leaks with flame.

5. While holding flame above barrel, open needle valve 1/2 turn.

6. Adjust barrel and needle valve for blue in blue flame.

Always light burner in open space on lab counter. After you have adjusted it for the flame needed move it into position. One person in lab group is always responsible for maintaining the burner and flame.

Burner Procedure:

1. Light the burner according to our rules. Observe the yellow flame which is produced because not enough air is admitted to give complete combustion. The yellow color is caused by small particles of unburned carbon which become incandescent.

2. Now rotate the barrel until the flame is entirely blue. Two different zones should appear when the burner is correctly adjusted. Too much air should not be admitted as it may cool the flame or blow it out entirely. After having the teacher confirm a good hot, blue flame draw a diagram of the flame (use labels and descriptions). Indicate on your diagram of the flame where the hottest part of the flame is located.

See the Web Links to the left for more information.

Bunsen burner barrels can be rotated, either opening or closing the barrel, to adjust the flow of air or oxygen, thereby controlling the flame.

What does a yellow flame mean on a gas furnace?

If you are burning natural gas, it means that the burner is dirty and not getting anough air. If left untreated it will lead to sooting and possibly carbon monoxide problems. Get the burner serviced immediately. If you are burning propane gas, there will be a yellow "tip" to the flame, this is a normal condition. The flame should not be all yellow however, this indicates the same problem as with natural gas.

Give one advantage of a scanning electron microscope over a transmission electron microscope?

The SEM has become more popular than the TEM as it can produce images of high resolution, greater clarity and three dimensional quality and requires less sample preparation.
