Yes, because the substances can be separated apart physically.

How do elements and compounds compare to a mixture?
In a mixture the two materials are combined but they do not bond, or react with each other, indeed they can only be formed by mechanically mixing the two substances. Mixtures can often be separated back into the original materials. The properties of a mixture are close to those of the two materials that make up a mixture. A compound is formed when two substances are chemically bonded to each other. These have different physical and chemical properties from the substances they were made from. These are also harder to return to the original substances.
What are advantages and disadvantages of separation techniques of mixtures?
Advantages of separation techniques of mixtures include the ability to isolate and purify specific components, which can be useful in research and industrial processes. However, some techniques may be time-consuming, require expensive equipment, or be challenging to scale up for large-scale applications. Additionally, some separation methods may result in loss of material or may not be suitable for certain types of mixtures.
What is a example of separation using physical change?
Most materials in our world are mixtures. Very few materials are pure substances. The art of separating mixtures is important because it enables us to isolate pure substances. Mixtures are either homogeneous or heterogeneous. Homogeneous mixtures are uniform in composition. Heterogeneous mixtures are not. Salt water is a mixture of water and NaCl and is homogeneous if thoroughly mixed, with all the salt dissolved. Oil in water is a heterogeneous mixture. Both types of mixtures can be separated into their component parts by physical means. A salt water mixture can be separated by distilling or evaporating the water and collecting the salt residue. An oil and water mixture will separate into an oil layer and a water layer because the materials are not attracted to one another and gravity "pulls" the denser water beneath the less dense oil. Settling, filtration, chromatography, and manual methods are all means of separating the components of a mixture. Choice of method depends on the type of mixture and the characteristics of its components.
What mixtures can be separated by filtration?
For example a mixture of solid materials.
What Are Good 7th Grade chemistry Science Fair Projects PLEASE ANSR?
Testing the acidity of household substances using pH indicators. Investigating the reaction rates of different types of vinegar and baking soda mixtures. Studying the effects of different types of salts on the freezing point of water.
Can substances that have undergone a physical change be changed back to their original state?
Yes
Who discovered mixtures?
Mixtures have been known and used by humans for thousands of years, dating back to ancient civilizations. There is no specific individual credited with "discovering" mixtures. Mixing different substances together to create new materials or products has been a common practice throughout history in areas like food preparation, medicine, and industry.
Gas forms when two liquids are mixed is that a chemical change?
Physical reactions: freezing, boiling, evaporation, condensation etc. Chemical reactions: eg. heating, baking, decomposition etc. Physical mixtures - mixtures in which the substances are easy to separate and get back (done by physical reactions) eg. flour and rice grains - you can sieve them. Chemical mixtures - mixtures in which the substances are hard to separate and get back (done by chemical reactions) eg. cakes - u cant get the eggs and other stuff back.
How are mixtures and compounds alike?
A mixture is formed from compounds but both are formed from atoms.
Can you get back burnt substances to their original state?
No, you can't get back burnt substances to their original state as combustion is an irreversible reaction.
Two or more substances come together without forming a new substance is called what?
Only a mixture: sugar and water, salt and pasta, soil and sand.

Can a substance produced during a chemical change be easily changed back into the original substance?
In general, a substance produced during a chemical change cannot be easily changed back into the original substance. Chemical changes are characterized by the formation of new substances with different chemical properties than the original substances. Reversing a chemical change typically requires a different set of reactions or processes.
A physical change is described as this?
An object that is changed and can be changed back like silly putty. Chemical change is when an object is changed and cannot be changed back. ex. egg cracking
Which physical changes reversible?
reversible changes are substances that can be changed from one thing to another then back to the other thing again, like ice, when you heat ice it becomes a loquid, but if you put the ice back in the freezer then after a while it becomes a solid again, your welcome. :)

Can mixtures be heterogeneous and homogeneous?
I think you can if you take the solids then liquids out to evaporate and then you will have the individual ingredients back together.
