Real Life Application of Chemical Changes

Why can’t we get the original substances back in a chemical change?

In a chemical change, the original substances (reactants) are changed into new substances (products) with different chemical properties. This change is usually irreversible.

Are all chemical changes accompanied by a color change or temperature change?

Not all chemical changes involve a color change or temperature change. However, these are common signs of a chemical reaction.

Can we slow down or prevent chemical changes like rusting?

Yes, chemical changes like rusting can be slowed down or prevented by reducing the exposure of the iron to oxygen and water.

Why is photosynthesis important for life on Earth?

Photosynthesis is crucial as it produces oxygen, which is necessary for most organisms to survive. It also helps in reducing carbon dioxide levels in the atmosphere.

What happens to the food we eat in our bodies?

The food we eat undergoes chemical changes during digestion, breaking down complex food molecules into simpler ones that our bodies can absorb and use for energy, growth, and cell repair.

Chemical change refers to a process in which one or more substances are converted into new substances with different chemical compositions and properties. From the food we eat to the medicines we take, chemical changes play a crucial role in various aspects of our daily lives. These chemical changes happen when substances combine or break apart resulting in a new substance with different properties. These changes involve the rearrangement of atoms and the formation or breaking of chemical bonds.

In this article, we will learn about the chemical changes around us and their real-life applications.
