What is boron sulfide?

The melting point of boron sulfide is 563 degrees Celcius or 1045 degrees Fahrenheit. It has a mass of 117.82 grams per mole.\nThis compound reacts with water to form boric acid, which is used to produce hydrogen sulfide gas. Boron sulfide also reacts with water vapor in the air. Anhydrous, meaning "without water," conditions are necessary for proper handling.\nBoron sulfide is used in the manufacture of glasses that absorb infrared energy. It is also used as a sulfurizing agent in chemical reactions.

What are some of the bacteria that live on the skin?

Bacteria found on the body serve several purposes, including defending against pathogenic invaders, building immunity against pathogens and protecting against excessive inflammation, says The Scientist. Bacteria also alter the immune response of body cells and affect the bacterial existence in the surrounding environment. Bacteria that negatively affect the body cause inflammation and illnesses, such as staph infections.\nDiversity of the environment provided by the human body prompts changes within existing bacteria. Propionibacterium lives in oily or sebaceous areas close to the neck, head a..

What is the difference between absolute and relative location?

Absolute and relative location are two common methods of relating where streets, cities, stores and other important places are found on Earth. These systems of measurement are sympathetic to one another, with relative locations defined by their distribution around absolute locations on a map.\nAbsolute locations are used for scientific measurements. They are essential for cartography, meteorology and sciences that rely on the placement of physical landmarks on the Earth's surface to make accurate predictions or generate clear conclusions. Even astrology and space exploration need absolute..

What are examples of solidification?

Another example of solidification is where milk, water and liquid foods harden when stored in a refrigerator. Just like other physical changes, solidification does not change the chemical identity of the substance. Other instances of chemical change are melting or fusion where solids change to liquids, and sublimation where solids change to gas. Liquid changes to gas in a process called evaporation or boiling while gas changes to liquid in a process called freezing or solidification.

What are some negative effects of space exploration?

Space exploration can have a negative impact on the environment. When rockets launch into space, their engines let out gases and debris such as aluminum oxide and soot. These substances can damage the ozone layer and contribute to global warming.However, space travel is not nearly as commonplace as car or airplane travel, which also release harmful substances into the atmosphere. Therefore, space exploration does significantly contribute to global warming. As space exploration becomes more commonplace, scientists must tackle environmental issues associated with rocket launches.In addition to g..

How do scientists classify rocks?

Igneous rocks are those that formed in the undercrust and later extruded to the surface. Some igneous rocks flow to the surface as molten lava, while others erupt in less viscid masses called tephra. Other igneous rocks, called plutons, rise near the surface strata but stop and gradually cool before they are exposed by erosion. Obsidian is an example of an igneous rock that emerges as lava and cools, and granite is typically formed as a pluton under the crust.\nSedimentary rock is formed after rocks of other types erode away from their beds and are transported to a common dump site. The charac..

What are the functions of collagen fibers?

Dr. Anne Marie Helmenstine says collagen is the most common protein in humans. Collagen fibers, along with keratin, make the skin strong and waterproof. Skin elasticity is also due to the presence of collagen fibers and keratin, and wrinkles form when there is less collagen available to support the skin.\n\nCollagen fibers are also found in connective tissue. This type of tissue supports muscle tissue, nerve tissue and epithelial tissue. The functions of connective tissue include nutrient transport and inflammation, according to experts from Southern Illinois University School of Medicine.

What is the function of hemoglobin?

The most essential task of hemoglobin is binding oxygen to it, explains InnovateUs. The higher the amount of oxygen molecules that bind to hemoglobin, the more oxygen reaches all parts of the body. With the help of external chemical factors such as carbon dioxide, pH and DPG (2, 3-diphosphoglycerate), the hemoglobin molecules take up oxygen molecules in the lungs and send them to different tissues in the body.\nOn HowStuffWorks, Carl Bianco explains that oxygen is released in the capillaries to be used by the body cells. Hemoglobin carries 97 percent of the oxygen that is transported by the bl..
