Answer:

Consider the following situations of daily life and think what happens

when –

 milk is left at room temperature during summers.

 an iron tawa/pan/nail is left exposed to humid atmosphere.

 grapes get fermented.

 food is cooked.

 food gets digested in our body.

 we respire.

In all the above situations, the nature and the identity of the initial

substance have somewhat changed. We have already learnt about physical

and chemical changes of matter in our previous classes. Whenever a chemical

change occurs, we can say that a chemical reaction has taken place.

You may perhaps be wondering as to what is actually meant by a

chemical reaction. How do we come to know that a chemical reaction

has taken place? Let us perform some activities to find the answer to

these questions.

\bf\huge{Answer :}

Combustion of Magnesium in air

1. Reaction :

  • \bf{2Mg+O_2 \longrightarrow 2MgO}

2. No of Reactants :

  • In the above reaction, there are 2 reactants. (Magnesium and Oxygen)

3. No of products :

  • One
  • Magnesium and oxygen reacts together and formed Magnesium oxide as a product.

4. Type of chemical reaction :

  • Combustion reaction

\bf\huge{ Additional \:information :}

Chemical reaction: It is a process in which one or more reactants react to form a new product is called a chemical reaction.

Types of Chemical reactions:

  • Combination reaction
  • Decomposition reaction
  • Displacement reaction
  • Redox reaction (Oxidation and reduction reactions)
  • Exothermic and Endothermic Reactions.
