What happens is the composition of the compound becomes different and the composition of the mixture stays the same because you can have many types of mixtures.

The composition of a mixture can vary unlike a compound explain why?

A mixture is a physical combination of two or more substances that are not chemically bonded, allowing their composition to vary. This is because mixtures retain the properties of their individual components and can be easily separated through physical means, while compounds are chemically bonded in fixed ratios, resulting in consistent composition and properties.


Is a piece of ice melting and reacting with sodium a physical or chemical change?

The melting of ice is a physical change, as it changes from solid to liquid without altering its chemical composition. However, when the melted ice reacts with sodium to form a new compound, it is a chemical change because the chemical composition of the substances involved is altered.


Do compounds have variable composition?

No. Compounds have a definite composition, therefore they are pure substances. For example, water always has the formula H2O, sodium chloride (common table salt) always has the formula NaCl, and glucose (blood sugar) always has the formula C6H12O6.


Two or more compounds mixed together?

When two or more compounds are mixed together, they do not undergo a chemical reaction to form new substances. Each compound maintains its own chemical identity and properties. This is a physical change rather than a chemical change.


When a mixture of iron and sulfur are heateda compound called iron sulphide is producedwhat type of change is this?

This is a chemical change because a new substance, iron sulfide, is formed with different properties compared to its original components, iron and sulfur.

How is the way a mixture is combined different from how compound is combined?

Is sugar water a compound or mixture or element?

It is both. A compound mixture is made of pure elements. For instance; salt is made of sodium chloride. Sodium voilently reacts with water, and chloride is extremely toxic, but when you eat salt, nothing happens. Why? A chemical change undergoes. A compound is 2 or more elements chemically mixed.


What kind of change occurs when a mixture forms?

A mixture is a solution of a compound or the liquid state of a compound. When you make a solution of a salt, the salt will solute in the solvent, and go to the ionic state. Example, NaCl in water: NaCl(s) -> Na+(aq) + Cl-(aq)


When you create a mixture and a change occurs it is called a?

When you create a mixture and a change occurs, it is called a physical change. This means the substance's state or appearance has altered, but its chemical composition remains the same.
