An endothermic reaction takes in energy from the surroundings as heat. This means the temperature of the surroundings will decrease. EXOTHERMIC An exothermic reaction gives out energy to the surroundings as heat. This means the temperature of the surroundings will increase.

What happens when limestone is heated? - Quora

When limestone is heated strongly, the calcium carbonate it contains absorbs heat (endothermic) and decomposes to form calcium oxide (also known as quicklime or lime). This is also a link in the limestone cycle. Here are other reactions. The reaction of calcium oxide with water produces calcium hydroxide. Calcium hydroxide is known as slaked lime.

When limestone is heated strongly? - pkh.rescrf

Baking soda, or sodium bicarbonate (NaHCO 3), is a chemical that can undergo a decomposition reaction when heated. At temperatures above 176 degrees Fahrenheit (80 degrees Celsius), sodium bicarbonate starts to break down into three compounds, forming sodium carbonate (Na 2 CO 3 ), water (H 2 O) and carbon dioxide (CO 2 ) .

Why is respiration considered an exothermic reaction explain?

Therefore, respiration is an exothermic reaction and the heat produced is distributed throughout the body as energy and that is the reason when we breathe out or breath is warm. Why is respiration considered an exothermic reaction explain Class 10? An exothermic reaction is a reaction in which energy is liberated out.
