The given reaction is endothermic or exothermic has to be discussed. CaCO 3 + heat → CaO + CO 2 Concept Introduction Endothermic Reactions: The chemical reaction in which heat energy is absorbed known as endothermic reaction. If the energy required to break the bond is greater than the energy released, then it is said to be endothermic reaction. Examples for endothermic reactions: Melting ice cubes. Evaporation of water. Producing sugar from photosynthesis.

(b)
Interpretation Introduction
Interpretation:
The given reaction is endothermic or exothermic has to be discussed.
N2 + 3H2→ 2NH3+ heat
Concept Introduction:
Exothermic Reactions:
The chemical reaction in which heat energy is released known as exothermic reaction. The chemical bond will determine whether the reaction is exothermic or endothermic. If the energy released by bond formation is greater than the energy required to break the bond, then the reaction is said to exothermic.
Examples for exothermic reaction:
Making ice cubes.
Formation of snow in clouds.
Condensation of rain from water vapour.
Rusting iron.
Burning sugar.
(c)
Interpretation Introduction
Interpretation:
The given reaction is endothermic or exothermic has to be discussed.
CO + 3H2+ heat → CH4+ H2O
Concept Introduction:
Endothermic Reactions:

(d)
Interpretation Introduction
Interpretation:
The given reaction is endothermic or exothermic has to be discussed.
2N2+ 6H2O + heat→ 4NH3+ 3O2
Concept Introduction:
Endothermic Reactions:
The chemical reaction in which heat energy is absorbed known as endothermic reaction. If the energy required to break the bond is greater than the energy released, then it is said to be endothermic reaction.
For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically:
1:1 (one mole of EDTA per mole of metal ion)
2:1 (two moles of EDTA per mole of metal ion)
1:2 (one mole of EDTA per two moles of metal ion)
None of the above
