No, a chemical change is not a temporary change; it is usually permanent. During a chemical change, the substances involved undergo a transformation that alters their molecular structure, resulting in new substances with different properties. Unlike physical changes, which can often be reversed, chemical changes typically cannot be undone without undergoing another chemical reaction.
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
A chemical change is when a substance undergoes a transformation that results in the formation of one or more new substances with different chemical properties. This typically involves the breaking and forming of chemical bonds between atoms. Examples of chemical changes include rusting of iron and burning of wood.
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
a physical change is the form of matter but not in its chemical identity or is when the state or shape of matter is changed.physical change is reversable or temporary while a chemical is permenent or cannot be reversed.a chemical change is a change in which one or more kinds of matter are transformed into a new kind of matter.
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Burning is an oxydation reaction so a chemical change.
Product is a temporary or permanent change of a object/objects by changing its chemical composition .
Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
Explain how a mixture of sand and salt can be separated.
physical change.the condition can be reversed by changing the temperature & it is only a temporary change.
It is physical. The wire changes shape, but it is still made of the same materials.
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
both physical and chemical change occur
