The solutions are designed by subject matter experts in a simple and precise manner.
The chapter covers topics such as balanced chemical equations, types of chemical reactions, and oxidation-reduction reactions.
Examples of chemical reactions and their balanced equations are provided, along with explanations of exothermic and endothermic reactions.
The importance of balancing chemical equations is emphasized to satisfy the law of conservation of mass.
The solutions are available in both English and Hindi medium for CBSE, Uttarakhand, Bihar, MP Board, Gujarat Board, and UP Board students.
Chemical reactions involve the formation of new substances.
Chemical equations represent the reactants and products of a reaction.
Balancing chemical equations ensures that the number of atoms and charge is conserved.
Different types of reactions include combination, decomposition, displacement, and double displacement.
Oxidation involves the addition of oxygen, while reduction involves the removal of oxygen.
Endothermic reactions absorb heat, while exothermic reactions release heat.
Corrosion is the gradual eating away of metals due to air, moisture, or chemicals.
Rancidity is the spoilage of food due to the oxidation of fats and oils.
Paint and nitrogen flushing can prevent corrosion and rancidity, respectively.
Respiration is an exothermic process that produces energy, carbon dioxide, and water.

Decomposition reactions are the opposite of combination reactions.
Decomposition reactions involve a compound breaking down into two or more compounds/elements.
Most decomposition reactions are endothermic.
Examples of decomposition reactions include the heating of mercury oxide and calcium carbonate.
Displacement reactions involve one element displacing another due to its greater reactivity.
Double displacement reactions involve two anions and two cations switching places between two compounds.
Precipitation reactions involve mixing soluble ions in separate solutions to form an insoluble compound.
Rusting of iron is a common form of corrosion caused by the oxidation of iron by oxygen in the air.
Rancidity is the unpleasant smell and taste produced by the oxidation of fat and oil in food.
Applying paint on iron articles reduces the rusting of iron.
Chemical reactions involve the transformation of chemical substances into new substances.
Chemical equations represent chemical reactions using symbols and formulae.
A balanced chemical equation has equal numbers of atoms on both sides of the equation.
Oxidation is the gain of oxygen or loss of hydrogen, while reduction is the gain of hydrogen or loss of oxygen.
Redox reactions involve both oxidation and reduction.
Combination reactions involve the combination of two or more substances to form a new product.
Decomposition reactions involve the breakdown of a compound into simpler products.
Displacement reactions occur when a more reactive metal displaces a less reactive metal in a compound.
Double displacement reactions involve the exchange of ions between two reactants, forming new compounds.
Precipitation reactions result in the formation of an insoluble mass called a precipitate.
