Which statement best describes a chemical change?

Which statement best describes why a chemical change is different from a physical change? A chemic alter results in a dissimilar state of matter, and a physical change results in a new substance being formed. A chemical change is used past scientists to create new substances, and a physical change happens naturally.

Chemical changes occur when a substance combines with another to class a new substance, called chemical synthesis or, alternatively, chemic decomposition into two or more different substances.

which best describes a physical alter? All substances are capable of undergoing physical changes. Whatever change that occurs without altering the chemical composition of a substance is a physical alter. Physical changes tin can include changing the colour, shape, state of matter, or volume of a substance.

Keeping this in consideration, what describes a chemical change?

substantive. Chemistry. a commonly irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a alter in their chemical properties or composition, resulting in the formation of at to the lowest degree ane new substance: The germination of rust on atomic number 26 is a chemical change.

Which is an example of a chemical change?

Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are humid, melting, freezing, and shredding. The only fashion to reverse a chemic change is via another chemical reaction.

Is boiling h2o a chemic change?

Boiling waterBoiling water is an example of a physical alter and not a chemic alter because the water vapor still has the same molecular structure as liquid h2o (H2o). If the bubbles were caused by the decomposition of a molecule into a gas (such as Water →H2 and O2), then boiling would be a chemical change.

How can you identify a chemical change?

What is chemic reaction explain with example?

A chemic reaction happens when one or more chemicals are changed into ane or more than other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.

Is freezing water a chemic change?

Freezing h2o is NOT a chemical modify. Information technology is a physical i. Water molecules remain as water molecules, still two hydrogen atoms and one oxygen atom. And so there is no chemical changes taking place.
