new substance-with new identity and properties.
chemical reaction: A process of formation of
chemical equation: symbolic representation of chemical ren.
.
Balanced equation: The equation in which number of atom of each elementon both side are equal.
Chemical reaction should be balanced bez only a balanced chemical equation tell us the relative quantity of each eractant &
product envolved in, the
Hit and Trial method: The method of balancing an equation is called Hit & Trial method as we make
to balance a chemical equation using smallest whole number coefficient.
ENDO Fesoy (s) Δ Feroz (s) + 502(g) + 50319)
Pb(103/2 (s) Pbo (s) + Noz (g) + 021g)
Endothermic ran: The reaction in which energy is absorbed. Caco} (s) → Cao (s) + (02/9)
Exothermic: (Hy (g) + 021g) > CO2 + H2O
in which is evolved or released along with the product. 6H12 06cg)t 02cg, • Co2 (g)-16H20(1) +energy
Exothermic ren: Reaction → Decomposition of veg. matter into compost.
Combination ren: formed from two ♂ more reactant.
single product?
Decomposition Dan: Reaction in which two or more product is formed by decomposing a single reactant.
→ Thermal: by Heat (Δ)
→ Electrolytic 8 by electricity (s)
→ Photo 8 by sunlight (Hg)
Displacement Reaction: This is a type of ren in which more reactive element displaces the less
active element from its own compound.
Double displacement Rin: Reaction in which there is an two different atom or group of atom (ion)
are exchanged or interchange.
Oxidation Reaction- Reaction in which Oz is added & H2 is removed.
Reduction - .. 02 is removed & H2 is added.
Redox reaction: Reaction in which both Oxidation & Reduction occurs simultaneously.
Rusting is the most common effect of corrosion.
Corrosion: The process of slowly conversion of metals into Fe + Hot 02 Feroz.xH20
Other effects of corrosion -
oxides, carbonates, sulfides etc by the action of af Ag + HIS →⅓!???:p hide)
acid of moisture. Cut costat no → Cucos. Culon),
basic capper carbonate
oil present in food material.
Rancidity: the process of oxidization of fats &
eat and its smell bcm unpleasant&
The food that become ranced, is unfit to
taste changes.
