Radioactive decay occurs when an alpha particle (Helium nuclei), beta particle (electron) or gamma ray (photon) is emitted from an atom’s nucleus. Alpha decay decreases the atomic number and the atomic mass because the nucleus loses two protons and two neutrons. Neutrons contain the mass of a proton and an electron but have no electric charge. When a neutron decays, it emits a negatively charged electron. The remaining mass combines with other protons in the nucleus, increasing its atomic number by one but retaining the total mass number.\nCarbon 14 provides a good example of the decay proce..

When used as a catalyst, sulfuric acid brings about reactions that would have otherwise been impossible. Since sulfuric acid is a strong acid, only small amounts of it are needed. It is an effective catalyst as it is able to donate protons to the reactants, and these donated protons help to lower the activation energy of a reaction.

Acetone is a colorless liquid that possesses a distinct smell and taste. Used in the manufacturing of a variety of products, including plastics, fibers, medical drugs and other chemical compounds, acetone is toxic in high doses. Acetone is a polar aprotic solvent that is capable of producing a variety of organic chemical reactions. Cooling acetone with dry ice produces a liquid solution that is commonly used to conduct chemical reactions at low temperatures. Fluorescent under ultraviolet light, acetone vapor provides an effective tracer for fluid flow experiments.\nAcetone has been produced si..

Active transport uses cellular energy to move molecules, while passive transport does not require cellular energy. Active or passive transport can only be used for molecules that are small enough to pass through the plasma membrane. Large molecules pass through cells by surrounding themselves with fluid sacks called vesicles. Proper passage of molecules to cell membranes is essential for cell functions such as aerobic respiration and protein production.

Kinetic energy is the energy of an object in motion. There are three forms of kinetic energy: vibrational, rotational and translational. Vibrational kinetic energy is the energy due to vibrational motion; similarly, rotational kinetic energy is the energy due to rotational motion. Translational kinetic energy is the energy of an object moving from one location to another.

A bone density scan is a diagnostic tool used to determine the amount of mineral matter per square centimeter inside a patient's bones, according to WebMD. Any substantial deviation from normal, either too high or low, can indicate a pathology.\nA bone mineral density test is performed by exposing the patient to two X-ray beams, explains NIH Osteoporosis and Related Bone Diseases. The second beam is used to remove the signature caused by soft tissue. Each bone of interest is scanned independently to control radiation dose.

Convection, one of the major types of heat transfer, involves energy moving from high areas of heat to low areas. If one area is hotter than a nearby area, heat will be transferred until both areas are the same temperature. Conduction occurs between two substances in contact. Energy is transferred as a result of molecular movement and interaction. Radiation heat transfers occurs on some level from all objects, as atoms emit energy as electromagnetic waves, which can be absorbed by other atoms.

Cattails exists largely in the Northern Hemisphere where they are found in wet habitats, including ponds, streams and marshes. There are two categories of species of cattails: broad leaf and narrow leaf. The most common species of cattail is the Typha latifolia. Cattails grow up to 10 feet tall and have very large leaves that look like blades of grass. They are most easily distinguished by their reproductive parts, including a large, brown, cylindrical shoot and a yellow spike. Cattails are typically found in dense clusters right on the edge and even up to 2 feet in the water. Cattails flower ..

The United States Naval Observatory's alternate master clock is located in Colorado Springs, Colorado and can be reached by calling 719-567-6742. The voice announcer for this number gives the time adjusted for the Mountain Standard time zone. If a phone is unavailable, the accurate time for every time zone in the United States is available on the Time.gov. or Time.is websites.

Selenium hexafluoride causes inflammation and irritation in the lungs and on skin. Touching liquefied selenium hexafluoride causes severe injury, frostbite and burns. The odor of the gas offers insufficient warning to overexposure; if someone smells selenium hexafluoride, contamination is already apparent. The gas is heavier than air, so it sinks to the bottom of an enclosed area.\nThe permissible exposure limit for the corrosive gas is 0.05 parts per million. Dangerous levels occur at two parts per million. Selenium hexafluoride is handled in a well-ventilated room to prevent asphyxiation.\nS..
