element
physical means only
Matter can be divided into two primary groups: pure substances and mixtures. Pure substances consist of a single type of particle and have consistent properties throughout, including elements and compounds. Mixtures, on the other hand, contain two or more different substances that retain their individual properties and can be separated by physical means.
Well, darling, a pure substance that can't be broken down further is called an element. It's like the Beyoncé of the periodic table - standing strong on its own without needing to mix and mingle with anyone else. So, remember, when it comes to pure substances, elements are the real MVPs.
Laurionite can be separated from other products through a combination of physical and chemical methods. Initially, it can be concentrated using techniques like flotation or gravity separation, given its unique density and mineral characteristics. Subsequently, chemical methods such as leaching with acids or bases can be employed to selectively dissolve other minerals while leaving laurionite intact. Finally, recrystallization may be used to purify the separated laurionite further.
chemical property
element
A Substance that can be separated into two or more substances is call a Composition, if not try Solution.----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- -----From Rafaelrz.Yes. A substance that can only be separated into two or more substances by a chemical change is a 'compound'. If a body can be separated into two or more different substances by only physical processes, then the body is a 'mixture'.
A compound can be separated into two or more substances through chemical reactions. Physical mixtures, such as an alloy or a solution, can also be separated into their individual components through physical means like filtration or distillation.
Is a pure substance such as an element. Remember elements can not be broken down further by chemical or physical processes.
Chemical property
The defining characteristic of a pure chemical substance is that any sample of it contains the same elements in the same mass proportions to one another.
Extraction is considered a physical change because it involves separating substances based on their physical properties, such as solubility or boiling point, without changing the chemical composition of the substances being separated.
in chemistry, chemical substance is a form of matters that has constant chemical composition and characteristic properties.it cannot be separated into components by physical separation methods. mixtures are the product of mechanical blending or mixing of chemical substance like elements and compounds ,without chemical bonding or other chemical change.
A mixture is when two or more substances are physically combined but can be separated by physical means, such as filtering or distillation. The substances in a mixture retain their individual properties and do not undergo a chemical reaction.
Matter is a pure substance if it can only be separated by chemical means, NOT physical means. This could be a compound or an element. The opposite is a mixture which can be separated/broken into smaller parts by physical means.
Chemical compounds or molecules cannot be separated into their individual elements by physical means. These substances require chemical reactions or processes, such as electrolysis or heating, to break the bonds between their constituent elements.
An example of a substance that cannot be separated into simpler substances by physical or chemical means is an element like gold or oxygen. Elements are made up of only one type of atom, so they cannot be broken down further by ordinary methods.
