Chemical Reactions & Equations - Core Revision Document
1. Chemical Reaction Definition & Reactants vs Products
A chemical reaction is a process in which chemical bonds break between reactant molecules to form new substances with entirely different chemical properties.
2. Key Characteristics of Chemical Reactions
- Change in State: E.g., Burning of Hydrogen gas to produce Liquid Water.
- Change in Color: E.g., Iron nail in CuSO₄ solution turns blue solution to pale green.
- Evolution of Gas: E.g., Zn + H₂SO₄ ➔ ZnSO₄ + H₂↑ (Pop test for Hydrogen).
- Change in Temperature: Exothermic (Heat released) or Endothermic (Heat absorbed).
- Precipitate Formation: E.g., Insoluble BaSO₄ precipitate in double displacement.
3. Corrosion & Rancidity (Everyday Effects of Redox)
Corrosion: Degradation of metals when exposed to oxygen, moisture, and acids. (e.g., Rusting of iron: 2Fe₂O₃·xH₂O, Green coating on copper).
Rancidity: Oxidation of fats and oils in food resulting in unpleasant smell and taste. Prevented by adding antioxidants, vacuum packing, or flushing with Nitrogen gas.
Types of Chemical Reactions Visualizer
Select any reaction type to simulate visual reactions in the beaker & view balanced equations.
Quicklime (Calcium Oxide) reacts vigorously with water to produce slaked lime (Calcium hydroxide), releasing a large amount of heat. This is an highly Exothermic Combination Reaction.
Chemical Equation Balancer
Adjust stoichiometric coefficients to satisfy the Law of Conservation of Mass.
Reactants Atom Count (Left)
Products Atom Count (Right)
Equation Unbalanced
Total atoms on reactant side do not equal product side.
Core Board Exam NCERT Activities
Most frequently asked laboratory activities in CBSE Class 10 Science papers.
Burning Magnesium Ribbon
Magnesium burns with a dazzling white flame to form white Magnesium Oxide powder. Sandpaper is used to clean oxide layer prior to burning.
Electrolysis of Water
Water decomposes into Hydrogen and Oxygen gas in 2:1 ratio by volume when electricity passes through acidulated water.
Thermal Decomposition of Lead Nitrate
Heating brown-tinted Lead Nitrate crystals produces pungent brown nitrogen dioxide fumes and yellow Lead Oxide residue.
