Are Name two categories used to classify properties matter?
Two categories used to classify properties of matter are physical properties and chemical properties. Physical properties can be observed or measured without changing the composition of the substance, while chemical properties describe how a substance changes into a new substance through a chemical reaction.
What is a combination of two or more atoms and has different physical and chemical properties than its individual atoms?
NaCl, or table salt.
What ae the two physical properties of minerals?
what are two physical properties about minerals
Why is 'Sand is mixed with salt' a physical change?
'Sand is mixed with salt' is a physical change because it involves a combination of two substances without altering their chemical identities. The individual particles of sand and salt retain their properties and can be separated by physical means, such as dissolving the salt in water or using filtration. No new substances are formed during this process, which is a key characteristic of physical changes.
Name two categories used to classify properties of matter?
Two categories used to classify properties of matter are physical properties, which describe the characteristics that can be observed without changing the substance's chemical composition, and chemical properties, which describe how a substance interacts with other substances to form new substances.
What are two properties of salt?
it is hydrogen and electrons
Two extensive properties of salt?
The mass and the volume
When two substances combine but no new substances are formed?
When two substances combine but no new substances are formed, they undergo a physical change rather than a chemical change. This can occur through processes like mixing, dissolving, or blending, where the individual properties of each substance remain intact. An example is mixing salt and water; the salt dissolves, but both the salt and water retain their original properties. Such mixtures can usually be separated by physical means, such as evaporation or filtration.
What are two physical properties of?
warmth and air
Is mixing flour and salt a physical Chan?
Mixing flour and salt is a physical change because it involves combining two substances without altering their chemical identities. The individual properties of flour and salt remain unchanged, and no new substances are formed. This process is reversible, as the mixture can be separated back into its components through methods like dissolving salt in water.
What are the chemical properties of rice mix with salt?
When rice is mixed with salt, there is no permanent chemical reaction between the two substances. The salt dissolves in water to form salt ions, which can enhance the flavor of the rice when absorbed during cooking. The physical properties of the mixture, such as taste and texture, are affected by the presence of salt.
When two pure substances are combined so that each of the pure substances retains its own properties the result is a?
When two or more substances are combined so each substance can be separated by physical means the result is a mixture. An example is dissolving salt in water. By boiling off all the water, the salt will remain.
