What are two properties of salt?
it is hydrogen and electrons
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.
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.
Heterogeneous matter composed of two or more pure substances each of which retains its identity and specific properties?
This is the definition of a mixture. Mixtures are combinations of two or more substances that are physically combined but not chemically bonded, allowing each substance to maintain its original properties. This can include mixtures like saltwater or air.
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.
Name two physical properties of salt?
soluble crystal form
What are two physical properties of water as it evaperates?
h2o
What are two properties of salt?
it is hydrogen and electrons
Are salt sugar and water mixtures or compounds?
Salt, sugar, and water are all mixtures. A mixture is a combination of two or more substances that are physically intermingled but retain their individual properties. In the case of salt sugar and water, each component can be separated by physical means, such as filtration or evaporation.
What is the two physical properties of steam?
If the steam is being produced by boiling water the physical property is gas and the chemical properties are H2O.

is adding salt to water a chemical or physical change?
It is a physical change because only the phase of the salt actually changes - the two compounds do not react. The salt dissolves in the water, but if the water evaporates, the salt is left behind in its solid state.
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.
Salt water a mixture or compound?
Salt water is a mixture because it is a combination of two substances - salt and water - that can be physically separated through processes like evaporation or distillation. The salt and water retain their individual properties within the mixture.
What is a combination of two or more atoms and has different physical and chemical properties than its individual atoms?
NaCl, or table salt.
