What are the 2 main groups of minerals in food?
The minerals found in food can be categorized into two groups; macrominerals, and trace minerals. Macrominerals are usually found in large quantities in food, and are required in larger quantities for the body. Trace minerals are found in small amounts in food, and are needed in smaller amounts in the diet. Macrominerals: Sodium, potassium, chloride, calcium, phosphorus, magnesium, sulfur. Trace minerals: Iron, zinc, iodide, selenium, copper, fluoride, chromium, molybdenum, manganese.
Is aluminum foil cut in half a physical or chemical change?
Cutting aluminum foil in half is a physical change. A physical change alters the form of a substance without changing its chemical composition. In this case, the aluminum foil remains aluminum foil after being cut in half, just in two smaller pieces. No new substances are formed during this process, so it is considered a physical change.
What substance would be made when carbon is burned?
The oxidation (burning) of carbon creates carbon dioxide, with some smaller amounts of carbon monoxide. This chemical reaction also releases energy, which is why coal is popular as a fuel in electric power plants.
Earth's original atmosphere was made up mainly of water vapor carbon dioxide and .?
The Earth's early atmosphere consisted of Carrbon Dioxide, methane, sulphur, ammonia, nitrogen and smaller amounts (aprox. 0.05%) of other gases.
Which is smaller 352nm or 0.00352km?
352 nanometers is smaller then 0.00352 kilometers
What elements is basalt made of?
Basalt is primarily made of silica, iron, calcium, and magnesium, along with smaller amounts of other elements like aluminum, sodium, and potassium. It has a fine-grained texture and is commonly found in volcanic regions as the result of cooled lava flows.
What atoms make up glass?
Glass is primarily made up of silicon dioxide (SiO2) molecules, which consist of silicon and oxygen atoms. Other elements like sodium, calcium, aluminum, and magnesium may also be present in smaller amounts to give glass specific properties such as transparency, hardness, or color.
How does Magnesium's atomic radius compare to aluminum?
Magnesium's atomic radius is smaller than Calcium's.
What elements are found on earth crust?
There are various parts that consist the earth's crust. It is mainly made up of two parts namely the lighter granite-based continental crust and the heavy basaltic oceanic crust. Some of the elements in the earth's crust include oxygen, silicon, magnesium, iron and so many more.
Scientist find dense rock on earths surface the is made of magnesium and smaller amounts of alum um and silicon What layer of earth might this rock help scientist study?
The dense rock made of magnesium, aluminum, and silicon is likely representative of the Earth's mantle, particularly the upper mantle. Studying this rock can provide insights into the composition, temperature, and dynamics of the mantle, as well as the processes that drive plate tectonics and volcanic activity. Additionally, it can help scientists understand the mineralogical transitions that occur between the crust and the mantle.
What are the components of Duralumin?
Duralumin is an aluminum alloy primarily composed of aluminum (about 90-95%), with the key alloying elements being copper (around 3-5%), along with smaller amounts of manganese, magnesium, and silicon. The addition of copper enhances its strength and machinability, making it suitable for aerospace and automotive applications. Its properties include high strength-to-weight ratio and good corrosion resistance, especially when treated or coated.
Is the mantle is composed mainly of metallic iron with small amounts of magnesium silicate minerals?
No, the mantle is composed primarily of solid silicate minerals rich in magnesium and iron, with smaller amounts of other elements like aluminum, calcium, and sodium. The metallic component is mainly found in the Earth's core, while the mantle is predominantly rocky in composition.
What elements makes up most of the mantle?
The mantle is mainly composed of silicate minerals rich in iron and magnesium, such as olivine, pyroxene, and garnet. These minerals form the majority of Earth's mantle due to their high abundance and density. Additionally, the mantle also contains smaller amounts of other elements like aluminum, calcium, and sodium.
What is earths exactly made of?
The Earth is made out of many things. Deep inside Earth, near its center, lies Earth's core which is mostly made up of nickel and iron. Above the core is Earth's mantle, which is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals. The rocky surface layer of Earth, called the crust, is made up of mostly oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Earth's surface is mainly covered with liquid water and its atmosphere is is mainly nitrogen and oxygen, with smaller amounts of carbon dioxide, water vapor and other gases..

What is the chemical symbol for duraluminium?
The chemical symbol for duralumin is AlCu. It is an alloy primarily composed of aluminum (Al) and copper (Cu). Other elements like magnesium (Mg) and manganese (Mn) can also be present in smaller amounts.
Does an aluminum ion have a larger or smaller radius than magnesium?
An aluminum ion has a smaller radius than a magnesium ion because aluminum loses an additional electron compared to magnesium, resulting in increased nuclear charge and greater attraction to the remaining electrons.
A silicate mineral must contain?
A silicate mineral must contain silicon and oxygen as its primary components. These elements form the building blocks of silicate minerals, with other elements such as aluminum, iron, magnesium, and calcium often present in smaller quantities. Silicate minerals are the most abundant mineral group on Earth and have a structure based on silicon-oxygen tetrahedra.
