A magnet attracts the Iron Filings and not the salt and sand (which do not contain Iron). Because iron is magnetic, salt and sand are not. Therefore the magnet only picks up the magnetic objects, in this case iron.
Pure salt, NaCL, is a chemical compound made from two elements. So yes it is a combination of two pure substances
Salt and pepper are both considered pure substances because they are composed of only one type of molecule. Salt is made up of sodium chloride (NaCl) molecules, while pepper is made up of various compounds such as piperine. Both salt and pepper maintain consistent chemical compositions throughout, making them pure substances.
no, it's a mixture. Salt is a pure substance, as is water, but together they are a mixture.
Salt water and table salt +water are the same thing- a solution. Aluminum, gold and iron are all elements (pure substances) and can not be broken down. Jello is a colloid. Muddy water is a suspension, plus salad dressing. Perhaps sugar could be called a pure substance. But it can be broken down into its' component parts. Tea also.
No, Iron is a homogeneous mixture as long as the iron is pure
ok so some examples of pure substances are gold sugar table salt distilled water(pure) iron filings
Pure matter substances can be elements, compounds, or mixtures where all components are the same throughout. Examples include pure water (H2O), pure iron (Fe), and pure table salt (NaCl).
Yes
Pure salt, NaCL, is a chemical compound made from two elements. So yes it is a combination of two pure substances
No, Salt is a compound of Sodium and Chlorine. A pure substance consists of only one type of element.
There are two types of substances: elements and compunds. Elements cannot be separated into simpler substances while compunds can. Take for example iron, pure iron is made of iron atoms, and they can't be divided into simpler substances, as such, iron is an element. On the other hand, salt is a substance that CAN be separated into sodium and chloride, so salt is a compound (and since sodium and chloride can't be furtherly separated they are elements). So, an element IS a substance, but not all substances are elements.

Table salt is a pure substance because it is composed of only one type of molecule, sodium chloride. Seawater is a mixture of different substances, including salt, water, and various dissolved ions. Sand is a heterogeneous mixture of minerals and particles, making it not a pure substance.
Salt and pepper are both considered pure substances because they are composed of only one type of molecule. Salt is made up of sodium chloride (NaCl) molecules, while pepper is made up of various compounds such as piperine. Both salt and pepper maintain consistent chemical compositions throughout, making them pure substances.
no, it's a mixture. Salt is a pure substance, as is water, but together they are a mixture.
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.
Examples of pure substances in food include sugar, salt, and baking soda. These substances consist of only one type of molecule and have a uniform composition throughout.
