Question

explain the usefulness of chemical changes in everyday life

Answer 1

$\huge\colorbox{pink}{Answer ✔}$

A chemical reaction is referred to as the process in which a set of chemical substances tend to react with one another, which, as a result, leads to their conversion from one form into several other different forms. The initial substances that are used the reaction are together known as reactants, whereas the final substances that get formed after the reaction has taken place are referred to as products. The chemical properties, in general, of both the reactants and the products, tend to differ from each other. Depending on whether the reaction gets initiated in the presence of energy or without the energy, it is divided into two different types, which is the spontaneous reaction which occurs on its own and the non-spontaneous reaction which needs energy to activate its process.

Answer 2

Answer:

Chemical change in day life.:

Chemical reactions occur everywhere in the world around you, not just in a chemistry lab. Here are 20 examples of chemical reactions in everyday life and a closer look at what’s happening on a molecular level.

How to Recognize a Chemical Reaction

The first step to recognizing chemical reactions in the world around you is to identify when a reaction is taking place. Chemical reactions cause chemical changes. In other words, substances interact and form new products. Not every change in matter is a chemical reaction. For example, melting ice, tearing a sheet of paper into strips, and dissolving sugar in water are physical changes that don’t change the chemical identity of matter.

Here are some signs of a chemical reaction. If more than one sign is present, it’s like a reaction has occurred:

Temperature change

Color change

Odor

Bubbling or gas production

Formation of a solid called a precipitate when liquids are mixed

20 Examples of Chemical Reactions in Everyday Life
