Answer 1

⭐️ ⭐️ ⭐️ ⭐️ ANSWER ⭐️ ⭐️ ⭐️ ⭐️

A] PRODUCT BECOMES HOT / WARM : Exothermic Reaction.

◆ EXAMPLES : 1] C + O2 -----> CO2 + HEAT
2] CaO + H2O -------> Ca(OH)2 + HEAT

B] PRODUCT BECOMES COOL DOWN : Endothermic Reaction.

◆ EXAMPLES : 1] C + 2S -----> CS2
2] CaCO3 --------> CaO + CO2

C] PRODUCT BECOMES INSOLUBLE : Precipitation reaction.

◆ EXAMPLES : 1] AgNO3 + NaCl ------> AgCl + NaNO3

2] FeSO4 + 2NaOH -------> Fe(OH)2 + Na2SO4
