No. Iron is a pure substance.
True for iron filing.
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.
Yes because it becomes iron oxide this is true.
False. When iron ore is heated in a blast furnace, the primary products are molten iron and slag, rather than pure iron and carbon dioxide. The carbon from coke reacts with the oxygen in the iron ore (primarily iron oxide) to produce carbon dioxide and molten iron, but the iron produced typically contains impurities and is not pure iron. Further refining processes are needed to obtain pure iron.
This is not true in general. Only in special cases!
True. Table sugar and salt are pure substances because they are composed of only one type of molecule – sucrose for sugar and sodium chloride for salt.
No. A number of animals are pure carnivores. Felines are one such example.
It is because water has no ions (only true for pure, distilled water).
I do not see a difference between true and pure love. I believe any love that is true will be pure and vice versa. Both pure and true love will be simple and easy with the right person.
A piece of pure Iron contains only one type of atom (Iron atoms) but there is more than one atom in it.
Only certain metals have an atomic arrangement that causes them to be attracted to a magnet. Nickel, iron, and steel are among the most common. Copper, gold, and silver are not arranged in a way that causes them to be attracted. True silver dollars (1935 and before) are 90% silver and 10% copper so they do not contain any magnetic metal. Modern dollar coins (1971 and later) aren't silver, they're mostly copper with the rest being nickel or manganese. There's not enough nickel in them to be attracted to a magnet.
