Question
What type of reactions are able to change products back to their original form?
- Reversible reactions
- Irreversible reactions
- Combustion reactions
- Combination reactions
Hint:
Physical change is a change in physical appearance only like changes in shape, size, etc.
The correct answer is: Reversible reactions
Reversible reactions are able to change products back to their original form,
- Physical change are temporary and thus can be reversed by different methods.
- Reversible chemical reactions occur when the reactants combine to create the products and then the products react to create the reactants once more.
- Such a reaction involves constant forward and backward reactions between the reactants and products.
