They have different molecular weights and chemical/physical properties.
A mixture cannot be separated with chemical change because a mixture is two or more substances which will retain their physical properties when combined. Mixtures are separated by physical means like filters, sifting, chromatography, centrifuge, electrophoresis and magnetic attraction depending on what the mixture is composed of.
it has 2 sets of chemical properties
Because there is no chemical reaction, the properties of the elements and compounds do not change when they form a mixture.
Their physical properties
The method of evaporation to separate substances in a mixture is purely physical because no chemical reaction occurs.
The physical properties of the things in the mixture. It could be that one part of the mixture is soluble, the other part insoluble - both physical properties. It could be that you use the boiling point of 2 liquids to separate them - physical properties. You could use a magnet if one part is magnetic and the other isn't - physical properties. And so on. But you are relying on physical properties rather than chemical properties.
A mixture is a combination of two or more subtances.Subtances in a mixture can be separated.This means that they are chemically combined.I would prefer physical change cause mixtures are made by physically combining two or more subtances.The solids,liquids,or gases in a mixture are not chemically combined.They can be easily seperated.
If it's a chemical, it has chemical properties. An oreo churro (whatever unholy abomination that might be) is a mixture of chemicals, each of which will have their own chemical properties.
yes
yes
A mechanical mixture is a mixture in which the components can be separated by mechanical means. In other words, there is no chemical bonding. The parts keep their own properties and chemical make up.
