Does aluminum rust?

When iron corrodes and forms rust, the rust flakes off easily. This leaves the metal vulnerable to even more rust. Eventually, the iron deteriorates altogether. The layer of oxide is one of the properties that makes aluminum a sought-after product in construction, especially in aluminum siding. Aluminum is also used for cookware, packaging, and car and boat parts.

How much is 185 centimeters in feet and inches?

The process of converting from centimeters to feet and inches starts by converting to inches and then converting that number to feet. The formula to convert to inches is the product of the number of centimeters and 0.39. The formula to convert to feet is found by dividing the number of inches by 12. The remainder is the number of inches.

What is the Law of Octaves?

Dictionary.com points out that in the Law of Octaves, an interval of seven elements separate two with similar properties. For instance, the first line of elements, hydrogen, fluorine, chlorine, bromine and iodine, are all halogens. Halogens cannot be found in nature with just a single atom. A hydrogen molecule always has two hydrogen atoms attached together. Also, fluorine, chlorine, bromine and iodine are all in the form of salt. They are either highly toxic or volatile. Another group of similar elements is the noble gases, which include helium, neon, argon, krypton, xenon and radon. They are..

How many neutrons does arsenic have?

Arsenic has been known since antiquity. Its name is derived from the Latin word arsenicum and the Greek word arsenikos. The German alchemist Albertus Magnus is thought to have been the first to isolate arsenic in 1250. Previously, arsenic compounds were mined by the ancient Greek, Egyptian and Chinese societies. Pure arsenic and its compounds are poisonous to most animals, including humans. This makes arsenic useful to the development of rat poison and several types of insecticides.

Where is biotite found?

According to Webmineral.com, biotite is not a single type of rock, but the name instead refers to a specific grouping of minerals that include phlogopite, siderophyllite and eastonite. Biotite itself is a type of mica, and it is also known internationally under the following names: iron mica, lepidomelane, manganophyllite, micaceous iron ore and oxybiotite. Webmineral.com also states that biotite contains atoms of potassium, magnesium, aluminum, iron, silicon, hydrogen, oxygen and fluorine.

Why does water pressure increase with depth?

At sea level, the atmosphere is pressing down on our bodies at 14.5 pounds per square inch (1 bar). This is equal to the pressure of our bodily fluids pushing outward. As a person dives in water, the pressure increases 1 bar for every 33 feet of depth. According to the National Oceanic and Atmospheric Administration, the pressure in the deepest part of the ocean is equivalent to a person trying to support 50 jumbo jets.

What glands are located in the neck?

The thyroid is a butterfly shaped gland that's found encircling the windpipe just below the voice box, claims MedicineNet. Its two "wings" are attached by a structure known as the isthmus.\nThe thyroid makes its hormones with iodine, states MedicineNet. Two of these hormones are thyroxine and triiodothyronine. The thyroid also produces calcitonin, which regulates the metabolism of calcium and helps it to build bones.

Where do stem cells come from?

Stem cells are the body’s raw materials. They are the cells from which all other cells with specialized functions originate. Under the appropriate environmental conditions in the body or laboratory, stem cells divide, forming more cells called daughter cells. These daughter cells generate into new stem cells through self-renewal. They may also differentiate into specialized cells with a very specific function, such as brain cells, blood cells, heart muscle or bone.\nSources of stem cells include bone marrow, placenta and cord tissue, amniotic fluid, teeth and umbilical cord blood. Stem cells..

How many atoms are in a molecule of oxygen?

The only diatomic elements are the non-metals. Diatomic elements consist of two atoms of the same element sharing electrons. Hydrogen, fluorine, chlorine, bromine and iodine are all diatomic elements and cannot be found as single atoms in their elemental form. These elements need only one more electron to fill their outer energy level, so they need to share or find just one more electron. Oxygen, on the other hand, shares two electrons. Because oxygen needs two more electrons to fill its outermost energy level to become stable, it wants to share electrons with others, especially with other ato..

What is the electron configuration for strontium?

Strontium has an atomic number of 38, which means it has 38 protons. In a neutral atom, an equal number of protons and electrons cancel each other out, resulting in a net charge of zero. As a result, one neutral atom of strontium must have 38 electrons.\n\nThese electrons are arranged in energy levels around the nucleus. This element's electron configuration gives students an easy way to determine how the electrons in a strontium atom are arranged. There are two in the first energy level, eight in the second energy level, 18 in the third energy level, eight in the fourth energy level and ..
