Question

write the type of change by giving an example in each case​

Answer 1

Step-by-step explanation:

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science of chemistry.

Answer:

• A chemical change results from a chemical reaction,Examples of chemical changes are burning, cooking, rusting, and rotting.
• a physical change is when matter changes forms but not chemical identity. .Examples of physical changes are boiling, melting, freezing, and shredding.
