Question

5. Chemical changes are ______ in nature.​

Answer 1

Answer:

CHEMICAL CHANGES ARE IRREVERSIBLE IN NATURE

Answer 2

Nature undergoes a variety of transformations. Physical and chemical changes are the two categories of changes that have been categorised based on the nature of the change.

Explanation:

• Chemical changes are those that occur in a substance, causing its chemical properties to change and the production of a new product.
• A physical change does not result in the formation of a new product. For example, in the case of rusting iron, once the iron has corroded to rust owing to moisture action, it cannot be transformed back to iron. As a result, one attempts to avoid it.
• As a result, we learn that chemical changes in nature are irreversible and permanent.
• Decomposition or synthesis can result in the formation of a new product during a chemical reaction. Organic and inorganic chemical transformations are also possible. Ripening of fruit, blooming of a bud to a flower, and many more organic chemical changes occur in nature. Explosions, matchstick burning, and other inorganic chemical reactions are examples.
