Why alloys are not mixtures?
An Alloy is not classed as a compound because no chemical reaction has taken place. Copper and zinc can be melted down and mixed to make brass. Even though brass has different properties to iron and zinc you cannot break it down into a single molecule of brass. There is no such thing as a brass molecule.
Is sterling silver nickel free?
Yes. Sterling silver is an alloy - silver is too soft to use on it's own, just like gold, and so they must alloy it with a non precious metal. Copper is usually used for this.
Can you calculate the melting point of an alloy?
To calculate the melting point of an alloy, one must consider the melting points of the individual elements in the alloy and their relative proportions. The melting point of an alloy is usually lower than that of its individual components due to the formation of a new phase. Phase diagrams are often used to predict the melting behavior of alloys.
How many elements must you count from the first alkali to the next?
You need to count seven elements before reaching the next alkali metal, which is in group 1 of the periodic table. These elements are hydrogen, helium, lithium, beryllium, boron, carbon, and nitrogen.
What are pistons made of?
Pistons are car parts often made out of a metal like stainless steel. These pistons are meant to move under high friction and must be a metal that can withstand the heat. +++ They are usually made of aluminium-alloy.
What alloy would you use to join metal parts explain?
There are several different alloys used for this purpose, depending on the requirements:solder, used in a process called soldering where low temperatures are required to avoid damage and the alloy does not need to provide strength to the joint (solder is traditionally an alloy of tin & lead but many modern solders have been reformulated to replace the lead with nontoxic metals)brass, used in a process called brazing where it is undesirable to melt the parts being joined but the alloy must provide strength to the joint (brass is an alloy of copper and zinc)alloys similar to that used in the parts themselves, used in a process called welding where both the alloy and the parts are melted and commingled to provide a joint as strong as the original metal parts themselves
What does a nonmetal elements need to do to form an anion?
A non metal must gain one or two electrons to form an anion
What metal is contained in guitar?
There are many guitars made with no metal at all. However, most guitars contain different types of metals.Let's start with types of strings that contain metal:> CLASSICALSilver-plated copper wire wrapped around nylonBronze (copper+tin) wire wrapped around nylon> ACOUSTIC BrassBronzeSilk + Steel> ELECTRIC NickelSteelNickel+SteelGearheads/Tuners/Machineheads/Elephant Ears/Cranks/Knobs/Tensioners:Again, they don't have to be metal, but usually are. Most machine heads are nickel or nickel alloys.Frets:Frets don't have to be metal, but are most often made of a nickel-steel or nickel-silver alloy. They can also be a copper alloy like bronze or brass, or they can be stainless steel.Pickups:Electric guitars and Acoustic-Electics have transducer pickups or electro-magnetic pickups (which must contain ferromagnetic material - which must be metal).
What is the chemical formula for metal?
There is no chemical formula for a metal. Metals are elements, whose chemical symbols are on the periodic table of the elements.
What two types of elements must join a for a covalent bond to occur?
Two non-metal elements must join for a covalent bond to occur. Covalent bonds involve the sharing of electrons between atoms to achieve a stable electron configuration.
Why is the mixture of two metals called mixture and not a compound?
Steel is a metal alloy, and hence an a heterogeneous mixture by definition. Steel contains other elements such as carbon and nickel. That being said an alloy can also be considered a substance. Substances can be pure/elemental or chemical mixtures.
Where is bronze found?
Bronze is a metal alloy consisting primarily of copper, usually with tin as the main additive, but sometimes with other elements such as phosphorus, manganese, aluminium, or silicon. All of these minerals come from the ground.
