True, a pure iron frying pan and a pure iron nail have the same density, as density is a property intrinsic to the material itself and is independent of the shape or size of the object. However, the manufacturing processes and any potential impurities in each item could affect their practical density in specific instances. But in a theoretical sense, pure iron's density remains constant regardless of the form it takes.

When iron rusts iron atoms are destroyed True False?
False, iron atoms are converted to iron oxide
The inner core contains genetic material true or false?
False. The inner core of the Earth is composed of solid iron and nickel, while genetic material is found in the nucleus of cells.
Is it true or false magnet usually attract the metal iron tin cobalt?
True. Magnets typically attract materials that are magnetic, such as iron, tin, and cobalt.
When a piece of metal is sitting outside and it begins to rust this is a chemical reaction is this true or false?
Both true and false. Rusting is both a chemical reaction (converting iron to iron oxide) and a physical process (the iron oxide absorbs water and hydrates, causing it to expand and fracture the rusting metal into pieces).
Is stars the size of the sun can produce elements heavier than oxygen true or false?
True. Our Sun will eventually produce elements as heavy as iron.
When iron rusts iron atoms are destroyed True False?
False, iron atoms are converted to iron oxide
Is ilmenite and rutile are ores of iron true or false?
True
True or false filing is attracted to a magnet?
True for iron filing.
When iron rusts iron atoms are destroyed true or false?
False. When iron rusts, iron atoms are not destroyed. Instead, iron atoms combine with oxygen in the presence of water to form iron oxide (rust), which causes the iron to corrode.
Is the myth about spinach being a rich source of iron true or false?
False. The myth that spinach is a rich source of iron is false. While spinach does contain iron, it is not as high in iron as previously believed.

true
True or False Iron is necessary for oxygen transport in red blood cells?
false
Is an iron frying pan a mixture a compound or an element?
An iron frying pan is made of iron, which is an element. Therefore, the iron frying pan is not a mixture or a compound, but rather a pure element.
The inner core contains genetic material true or false?
False. The inner core of the Earth is composed of solid iron and nickel, while genetic material is found in the nucleus of cells.
