How do you find Saturn through a telescope?

Select the best time of year and nightDuring the second half of 2014, viewing from the Northern Hemisphere, Saturn is best seen at its high point around 10 p.m. During this time, it appears amidst the constellation Libra near two of Libra's moderately bright stars, Zubenelgenubi and Zubeneschamali.Pick out SaturnIf you've chosen the right time, spotting the golden-colored Saturn is easy. As of late 2014, it's visible between two noteworthy markers in the sky: the bright star Antares on one side with the reddish Mars and the bluish white star Spica on the other.Choose a proper te..

What are a few retailers that supply argon gas?

PraxAir's web store features compressed argon gas in a number of different purities and concentrations. They sell 99.998% pure compressed argon, argon mixed with helium and argon mixed with hydrogen. They also sell liquid argon.\nThe web store for AirGas offers high pressure argon cylinders as single units or in bulk. They also offer a service to welders, called Welding Efficiency Analysis, that claims to maximize argon supplies at work sites.\nHarbor Gas also sells argon gas cylinders at its online store. As of October of 2015, one argon gas cylinder at Harbor Freight costs $89.99. Harbo..

What are some ways that the isotopes of an element differ from each other?

The total number of protons and neutrons in an atom's nucleus is represented by its mass number, and it differs from the element's atomic number across its varying isotopes. For example, the atomic number of carbon is 6, because its nucleus contains 6 protons. Carbon also has a range of isotopes which include a 6-neutron, 7-neutron and 8-neutron isotope. These three carbon isotopes are called carbon-12, carbon-13 and carbon-14, respectively. The atomic mass of each of these isotopes is derived by adding the number of neutrons in each isotope to the number of protons. The atomic mass ..

What is the cephalic region?

The cephalic region encompasses all of the individual regions of the head. It is divided along a plane that runs under the ears into an upper division, the cranial, and a lower region, the facial. The ocular, buccal and nasal regions refer to the eyes, cheeks and nose, respectively. The mental region is, counterintuitively, the chin. The otic region is divided into two areas that each contain one ear.\nThe cephalic region is the uppermost, or superior, region in the human body. Immediately beneath it lie the trunk and upper arm regions. Inferior to, or lower than, these is the abdominal region..

What is the function of the excretory system?

The skin is the largest organ in the excretory system. When an individual sweats, excess fluids and salt are released, which helps to regulate body temperature. Respiration through the lungs eliminates carbon dioxide from the bloodstream. The liver is another organ in the excretory system. It produces bile, which breaks down fat and other acidic materials. The liver also breaks down toxic chemicals, such as ammonia, that then move through the urinary system.\nThe kidneys are part of the urinary system, and they filter the blood for waste. Necessary material goes back into the blood, and the wa..

What is the definition of a supernatant liquid?

Precipitation in chemistry refers to the creation of a solid within a solution or within another solid during the process of diffusion. During this process, the solid formed is known as the precipitate. What causes the solid to form is known as the precipitant, and the supernate or supernatant is the area above the precipitate. A powder can also be derived from this process, and it is known as a flower.

What is the chemical formula for calcium sulfate?

Calcium sulfate is often found in its dihydrate form, gypsum. For dihydrates, every molecule of calcium sulfate has two corresponding molecules of water. Calcium sulfate also has a hemihydrate form, known as "plaster of Paris." This means that every two molecules of calcium sulfate in plaster of Paris has one corresponding water molecule. Since dehydrated calcium sulfate easily absorbs water to return to one of its hydrate forms, it is often used as a desiccant.

What is the density of neon?

Neon was discovered in London, England in 1898 by Scottish chemist Sir William Ramsay and English chemist Morris W. Travers. The name neon originates from the Greek word "neon" meaning "new." Neon has many different uses, the largest is to make brightly lit signs. It is also used to make high voltage indicators, and it is combined with helium to make helium-neon lasers.

What are some possible solutions to climate change?

By the middle of the century, the United Nations Environmental Program expects the human population to soar to more than 9 billion people. That said, it is important to realize that the more people on the planet, the larger the carbon footprint, and that contributes to global warming.Each year, more than 33 million acres of trees are cut down around the world. Without trees, there is little left to filter harmful gases from the air, leading to global warming.

Where does hydrogen peroxide come from?

Hydrogen peroxide also has antiseptic and antibacterial properties that make it useful for a variety of medical and cosmetic purposes. However, the chemical has to be severely diluted for uses, as solutions containing more than 8 percent hydrogen peroxide are corrosive to the skin.\nMost commercial grades of the chemical contain somewhere between 35 and 90 percent hydrogen peroxide in a solution of water and trace amounts of stabilizers.
