Answer 1

$\:\:\:\:\:\:\: \bold \green{Redox \: \: Reactions : - }$

It is also called reduction and oxidation reaction. In this reaction

• reduction of oxygen is called reduction.
• adding of oxygen is called oxidation.
• reduction of hydrogen is called oxidation.
• adding of hydrogen is called reduction.

$\: \: \: \: \: \: \: \: \: \: \boxed{ \sf{ZnO + C → Zn + CO}}$

• zn reduces oxygen so it is called reduction. while oxygen is added to carbon so it is called oxidation.

$\:\:\:\:\:\:\: \bold \blue{Decomposition \: \: Reaction : - }$

In this type of reaction a single reactant will decompose to two or many products.

$\boxed {\sf{FeSO4 → Fe2O3 + SO2 + SO3}}$

• Here we provide heat to ferrous sulphate crystals and they will decompose to give ferrous oxide, Sulphur oxide and sulphur trioxide.

$\:\:\:\:\:\:\:\bold\pink{Combination \: \: Reaction : - }$

In this type of reaction two or more reactant reacts to provide a single product.

$\: \: \: \: \: \: \boxed{ \sf{2Mg + O2 → 2MgO}}$

• Here magnesium will reacts with oxygen to give magnesium oxide.

$\bold \red{Exothermic \: and \: Endothermic Reaction}$

Exothermic reactions are those reaction in which heat is evolved while in those reaction which do not evolve heat is known as Endothermic reaction.

$\boxed{ \sf{CaO + H2O → Ca(OH)2+ heat ↑}}$

• It is Exothermic Reaction as there is heat evolving when Calcium Oxide reacts with water.

• Rusting of Iron is an endothermic reaction.

${ \:\:\:\:\:\:\:\bold{\purple{Displacement \: \: \: Reaction :- }}}$

In this reaction elements with highly reactivity displaces the elements with less reactivity.

$\: \: \boxed{ \sf{2Na + FeSO4 → Na2SO4 + Fe}}$

• In this reaction Sodium displaces the ferrous from ferrous sulphate solution and makes solution of sodium sulphate.
