What state of matter is magnesium?

Magnesium is classified as an alkaline earth metal and appears gray and white in color, although it can tarnish when exposed to air. In nature, magnesium is only found as part of a compound combined with other elements. It is the fourth most common element found in the earth, commonly found dissolved in seawater and in the planet's crust. Magnesium is highly flammable and burns with a white flame.

Where does plutonium come from?

The first sample of plutonium humans ever produced was made at the University of California in 1941. Researchers at the university bombarded a sample of uranium-238 with helium nuclei until it formed neptunium-238. This isotope has a short half-life. Within a few days, the sample had decayed into plutonium-238.\nAfter World War II, the United States extracted plutonium from spent uranium fuel rods on an industrial scale. Plutonium-239 is particularly useful for weapons and civilian power production. This work lasted for decades until the 1970s, when President Ford issued an executive order to ..

How do animals change for the seasons?

Many animals migrate to warmer climates when winter sets in. They do this for a variety of reasons, such as the need for warm shelter and to follow their food supply. Birds are known to travel between regular summer and winter habitats. The Arctic Tern travels one of the farthest distances, flying all the way from the North Pole in the summer to Antarctica in the fall. Whales, fish and caribou also migrate regularly.\nAnimals that do not migrate often go into a period of dormancy, or hibernation, during the winter months, awakening again in the spring. Bears, skunks and other mammals go into a..

What causes chemical bonds to break during a reaction?

According to Chemtutor, the Law of the Conservation of Mass states that there will always be the same amount of matter before and after a chemical reaction. This happens on the chemical level when molecules break apart, join together, or lose and gain electrons to form new elements. It also happens on the physical level when the chemical reaction causes elements to change their form. However, no matter can be created or destroyed during this reaction. It can only change form.\nOne example of a chemical reaction is the breaking down of simple sugars during fermentation. The carbon in the sugars..

Where can you find a moon chart for the month?

MoonConnection.com also offers Web code for moon calendars to be placed on a user's own website. StarDate explains concepts surrounding the moon's phases such as harvest and blue moons. Each of the charts can be searched by month and year, although StarDate does not show every day of the month, only full, half and new moons.

How does oil energy work?

Crude oil that is extracted from underneath the Earth's surface is made up of fossilized organic material. Because this oil is naturally occurring, it is technically a renewable resource. However, it takes millions of years to form and is depleting faster than it is being created, which means many consider it to be a nonrenewable and inefficient resource.When the oil is extracted from the ground, it is piped into a burner. Burning the oil creates heat, which is used to boil water. When the water is boiled, it creates steam that expands in narrow pipes, creating a lot of pressure. The pres..

How do you generate electricity?

Other methods of electricity generation include static electricity, photovoltaic, thermoelectric, piezoelectric and nuclear transformation. Static electricity was the first method discovered and is still used in a few modern devices, but it is a small percentage of electricity generation compared to other forms. The primary method of electricity generation is alternating current, which involves spinning turbines moved by wind, water or steam. As the turbine spins, it is connected to a large magnet inside of a loop of wire. The polarity of the magnet forces electrons to move along the transmiss..

How is matter described?

All items classified as having matter contain mass and weight. Mass refers to the quantity of matter that an object contains. However, mass is not to be confused with weight, which is a strong force generated by the force of gravity, or gravitational attraction, that pulls on an object. Mass is a basic property of an object that does not depend on that object's location. In addition to having common characteristics of mass and weight, all kinds of matter come in one of three forms: solids, liquids and gases. Solids are defined, structured and right and have fixed shapes and volumes. Rocks..

What is chlorogenic acid?

Chlorogenic acid occurs naturally in plants, and is an important part of their metabolic functions. The compound can be isolated in leaves and fruit for pharmeceutical use. In addition to its antioxidant uses, chlorogenic acid is also known to slow glucose release into the blood, making it a possible preventative measure for both cardiovascular disease and Type 2 diabetes. Chlorogenic acid is also promising in cancer treatment, inhibiting chemicals that contribute to tumor growth.
