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.

The type of sensor the meteorologists should use is Radar sensor.
<h3>Who is a meteorologist?</h3>
A meteorologist is a scientist who studies and works in the field of meteorology with the purpose of understanding or predicting the Earth's atmospheric phenomena.
The tools used by meteorologists in studying atmospheric
phenomena or conditions include:
- Thermometer for measuring air and sea surface temperature.
- Barometer for measuring atmospheric pressure.
- Hygrometer for measuring humidity.
- Anemometer for measuring wind speed.
- Pyranometer for measuring solar radiation.
- Rain gauge for measuring rainfall over a set period of time
- Radar sensor for observing severe storms.
Therefore, the type of sensor the meteorologists should use is Radar sensor.
In conclusion, a meteorologist should use Radar sensors to detect and predict the atmospheric phenomena in stormy weather.

I think it is called a Case study.
Hopefully it is correct! :)
