Key Concepts in Chemical Reactions

Chemical Reactions involve the transformation of reactants into products through various processes. Here are some essential concepts covered in Chapter 1:

1. Definition of Chemical Reactions: A chemical reaction occurs when substances undergo a change to form new substances. This can involve changes in physical properties, energy changes, and the formation of new compounds.
2. Types of Chemical Reactions:
   • Combination Reactions: Two or more reactants combine to form a single product.
   • Decomposition Reactions: A single compound breaks down into two or more simpler substances.
   • Displacement Reactions: An element displaces another in a compound.
   • Redox Reactions: Involves the transfer of electrons between substances.
3. Balancing Chemical Equations: It is crucial to balance chemical equations to obey the law of conservation of mass. This means that the number of atoms of each element must be equal on both sides of the equation.

PSEB 10th Class Science Solutions For Chapter 1 Chemical Reactions and Equations

To aid students in their preparation, here are solutions to some common questions from this chapter:

1. Question: Write a balanced equation for the reaction between hydrogen and oxygen to form water.
   • Solution:

      

     $$2H_2+O_2\to 2H_{2}O$$2H2​+O2​→2H2​O

2. Question: Identify whether the following reaction is a combination or decomposition reaction:
   $2Na+C{l}_2\to 2NaCl$ 

   2Na+Cl2​→2NaCl.

   • Solution: This is a combination reaction, as two reactants (sodium and chlorine) combine to form a single product (sodium chloride).
3. Question: What is meant by a redox reaction? Provide an example.
   • Solution: A redox reaction involves both oxidation (loss of electrons) and reduction (gain of electrons). For example:

      

     $$Zn+C{u}^{2+}\to Z{n}^{2+}+Cu$$Zn+Cu2+→Zn2++Cu

   In this reaction, zinc is oxidized while copper ions are reduced.
