Question

What is the entropy change calcium carbonate form calcium oxide and carbon dioxide?

Answer 1

Answer:

●Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.

Answer 2

Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely ... entropy ( So298) .... This form of illumination is known as a limelight
