Chemical change means the Conversion of one form into another form .
There are9 kinds of changes . just like
Solid -----> Gases
Gases------> Liquids
Liquids -----> Gases
and many other examples like this
Also can be defined as :
The conversion of Parent elements into Daughter elements is called chemical reaction .
The elements which form new elements are called "PARENT ELEMENTS "
And the new elements which are formed are called "DAUGHTER ELEMENTS "
chemical change is any change that results in the formation of new chemical substance . at the molecular level chemical change involves making or breaking of of bonds between atoms .these changes are iron rusting ,gasoline burning and others .
A chemical change is a change in which a substance turns into a completely different substance that can't be reversed.
A chemical change often happens when you burn wood, plastic, paper, cotton, etc.
" chemical reaction is a process that leads to the transformation of one set of chemical substances to another" ...Baking soda and vinegar ... make a good household cleaner getting rid of calcium deposit in your coffee maker.
"Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances. "
chemical change occurs when rain and cold temperatures changing rain water changes into snow crystals ... or water heated till it turns into steam
Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes 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.
