10g of CaCO3 is decomposed, 5.6g of residue is left and 4.4g of CO2 is escapes.
In general ,calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide. Reaction takes place like CaCO3(s)Heat⟶CaO (s)+CO2(g).
Substance breaks down into smaller species is known as decomposition. The Decomposition of limestone to calcium oxide (quicklime) and carbon dioxide on heating. When heated above 840°C, calcium carbonate decomposes, releasing carbon dioxide gas and leaving behind calcium oxide a white solid.

Answer:
objects observed in extra-galactic space (deep space) are shifting away or receding away from earth
Answer:
The answer is A. Non-corrosive.
Explanation:
Answer:
Ozone (O₃) gas
Explanation:
In the Earth's stratosphere, oxygen gas (O₂) is combined with atomic oxygen (O) to form ozone gas (O₃). This is very important because ozone protects the life on Earth from ultraviolet (UV) radiation from the Sun. UV radiation is high-energy radiation, and it is very dangerous for living organisms. Ozone molecule (O₃) absorbs UV radiation and it breaks down by forming O₂ and atomic oxygen (O) again. In this way, it protects the Earth from nocive radiation.
Answer: A.
Explanation: Hope this helps
