What else can I help you with?
Alloys are commonly used in manufacturing. Which of the following is not a reason to use an alloy instead a pure metal?
Alloys are not used instead of pure metals when the desired properties of the pure metal are specific, such as in cases where high electrical conductivity or chemical purity is required.
Who developed a way of making iron strong enough to use for weapens?
The process of making iron strong enough to use for weapons was developed by ancient civilizations, such as the Hittites and Egyptians, through a technique called carburization. This involves adding carbon to the iron to create steel, which is stronger and more durable than pure iron.
Why is iron used to make girders for building?
Iron is used to make girders for building because of its strength and durability. It has a high tensile strength, which allows it to bear heavy loads without bending or breaking easily. Additionally, iron girders are resistant to corrosion, making them ideal for use in construction projects where long-term stability is important.
What did they use to iron the clothes?
An iron.
Why are iron needles good in compasses?
Iron needles are good in compasses because they are easily magnetized, allowing them to align with the Earth's magnetic field. This alignment helps to indicate the cardinal directions (north, south, east, west) accurately. Additionally, iron needles are lightweight and durable, making them practical for compass use.
Why is steel rather than pure iron used to make car bodies?
It is because the iron is not strong enough to be able to handle the pressures that steel can. Pure iron is to soft and weak to be of any use and the iron from the blast furnace has too much carbon in it to be useful. That is the real reason
Use diagram to explain why pure iron is described as an element?
Pure iron is described as an element because it consists of only one type of atom, which in this case is iron. This diagram shows the arrangement of iron atoms within a sample of pure iron, highlighting how they are all identical and cannot be further broken down chemically. Each iron atom has the same number of protons in its nucleus, defining it as iron on the periodic table of elements.
Alloys are commonly used in manufacturing. Which of the following is not a reason to use an alloy instead a pure metal?
Alloys are not used instead of pure metals when the desired properties of the pure metal are specific, such as in cases where high electrical conductivity or chemical purity is required.
Why do iron use in structures?
Iron/steel is used in building because of its great strength and, the fact that it is relatively abundant, thus inexpensive.
Why isn't steel an element?
The main element from which steel is made is Iron (Fe) but steel is not pure - (not just iron) it is an alloy of iron and other elements, primarily carbon. Element MUST be pure substances and if steel were pure it would be Iron.
How do you get pure iron and what is it used for?
we get it from reacting it in a blast furnace firstly we react oxygen and carbon coke to form carbon dioxide which then reacts further with the coke to form carbon monoxide which then reacts with oxygen from the iron oxide to form carbon dioxide and pure molten Iron. And we use it occasionaly in medicine as iron supplements or in anylytical chemistry.
What are the elements in iron tools?
Strictly speaking, we rarely use pure iron, particularly not in tools. Mix in a Little of some other stuff, like coal(carbon) Molybdenum, Chrome, Nickel etc you get a falmily of Alloys called steel. Steel is stronger than pure iron and more likely to be used in "iron" Tools.
Why is sandstone good for its use?
it is used for building
How do you make an iron?
Just mine some Iron Ore (use a pickaxe on a brown rock) and then smelt it in a furnace (found in various places). There is a 50% success rate. If the ore is pure, you will retrieve a bar of iron.
What did the ancient egyptians use for building?
They used limestone for most of their pyramids and mostly pure brute strength to carry the limestone.
What was the archetypal use of iron in building construction?
a form of masonry reinforced with imbedded iron bars that is regarded as the precursor of reinforced concrete. English builders began relying on iron in the construction of factories about 1850
Why is it better to use aluminum instead of iron for building bikes?
Done correctly an aluminoum bike will be just as strong but quite a bit lighter than an iron bike.
