Calcium Carbide The Illuminating Chemical Compound

Just like with other calcium compounds that contains the suffix ide in their names, calcium carbide is not also associated in the production of calcium-based supplements. It is commonly used on modern industrial applications as well. Read on the preceding contents of this article and learn more about calcium carbide.

Chemical Compound Reaction

Bearing the chemical formula CaC2, calcium carbide is produced through the process of electrostatic discharge by means of mixing carbon and lime at high temperature. When reacted with water, it produces acetylene. Such reaction is the principle behind the production of dissolved acetylene which is the only modern industrial use of calcium carbide.

Application

The most common application of calcium carbide is on so-called carbide lamps (also known as acetylene lamps) wherein it uses acetylene gas which is produced by means of combining the chemical compound and water. Such lamps were formerly used in mines.

Calcium carbide in this application takes the form of small pellets or chunks that is placed on the lower chamber of the lamp. Its upper chamber is filled with another reactant, which is water. There is a screw valve or similar mechanism which controls the drip rate of water to the lower chamber where the calcium carbide is stored. Such water drip rate control results to the production of acetylene gas. It results in control of the size of the flame as well as the quantity of light that it produces.

The reaction of water with calcium carbide generates enough quantity of heat apart from the flame. In cold cave conditions, the heat can be used to save someone from hypothermia.

After the entire quantity of calcium carbide is reacted with water, the lower chamber contains now a wet paste of calcium hydroxide or caustic lime which is emptied in order to be refilled for the next usage. The caustic lime is toxic on humans and animals and must be deposited on a place wherein no one will be affected.

The next application of calcium carbide is the flare which is a type of pyrotechnic that emits a brilliant light as well as intense heat without the occurrence of an explosion. It is commonly used as a signal and illumination (especially on small fishing boats) as well as defensive counter measures in military and civilian applications.

Calcium carbide is only handled within industrial production. Individuals who work with this chemical compound always take some precautionary measures to avoid any untoward incident that may happen due to mishandling of calcium carbide.

Crockpot Recipes for Low-Fat Dieters

You may not believe this but there are actually a countless number of crock pot recipes for people who are on a low-fat diet. Apparently, such low fat crock pot recipes are intended for people who are watching their health and their weight very carefully. In this regard, we would want to share at least two of the low fat crock pot recipes that most dieters prefer to prepare.

Arroz Con Pollo is one type of a low fat crock pot recipe that we highly suggest. You will need to prepare such ingredients as two tablespoons of freshly chopped cilantro, two cups of cooked rice, ten ounces of frozen peas that have been thawed, two tablespoons of red wine, one half cup of chicken broth, eight pieces of chicken thighs that do not have skin, two teaspoons of chili powder, one teaspoon of oregano, one clove of crushed garlic, one fourth teaspoon of pepper, and one half teaspoon of salt.

Mix such ingredients as chili powder, oregano, garlic, pepper, and salt together in a bowl. Such spice mixture should be sprinkled all over the chicken pieces. Once each of the chicken pieces is sprinkled with the spice mixture, you may place all of them in a crock pot. The wine and the broth should then be poured all over the chicken pieces. Cover the crock pot and let it cook for at least five to six hours using low temperature. After five to six hours, remove the chicken and set the crock pot on high temperature. Add the peas soon thereafter and cover the crock pot again and let the ingredients be cooked for another seven to ten minutes. The cooked rice as well as the chicken should then be added into the crock pot. Before serving, make sure to sprinkle the freshly chopped cilantro on the dish.

Another low fat crock pot recipe that we suggest is the recipe for Basil Chicken. This is also an easy-to-prepare dish as it only requires few ingredients and can also be cooked while the crock pot is running unattended.

The ingredients include one half whole green pepper that is sliced, one can of cream of celery soup, one half teaspoon basil, one half teaspoon of pepper, and four whole chicken breasts that are skinless.

To begin the procedure for this low fat crock pot recipe, you must place first the skinless chicken breasts in the crock pot. The chicken should then be sprinkled with basil and pepper. The cream of celery soup should then be poured over the chicken pieces. Afterwards, the sliced green pepper should be placed on top of the chicken that is covered with soup. Cover the crock pot and let it cook for approximately eight hours. The crock pot should be set on low temperature for this low fat crock pot recipe. You do not have to wait for eight hours for this recipe to be cooked. There are instances when six or seven hours will do. This recipe only contains four grams of fat and is composed of 55 grams of protein and three grams of carbohydrates.
