Hematite is a naturally occurring mineral and a common form of iron ore. the following statements describe physical and chemical changes occurring to hematite. which statement describes a chemical change? a. the hematite particles separate from each other but remain the same substance. b. the hematite particles rearrange to form a new substance. c. the hematite particles are mixed with particles of a different substance. d. the hematite particles vibrate more quickly when they are heated. e. the hematite particles are moved from one location to another location.

Hematite particles when gets rearranged to form a new substance,  is an example of a chemical change.

As a chemical changes is usually a change where a substance undergoes a chemical change and forms a new substance; which cannot be easily reversed into reactants by any simple physical methods.

In this example the hematite ore forms a new substance by an irreversible chemical change.

The Hematite particles rearrange to form a new substance. It describes a physical and chemical change occuring to Hemtite. When these particles get rearranged to produce a new substance, such a change is known as chemical change.

Chemical changes are often a variation in which an object changes chemically and become into a new species. Such a species cannot be reversed into reactants through any simple physical methods. Hematite particles form a new substance by an irreversible chemical change which cannot form reactants by-products.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
