    Thermal decomposition of calcium carbonate.

    In general, we heat CaCO3 to temperature of approximately 825°C it decomposes into calcium oxide and liberates carbon dioxide gas:* CaCO3 →825°C→ CaO + CO2* Is it possible to heat the calcium carbonate at temperatures below 825 degrees Celsius.

    Thermal decomposition

    Hi, I have a question that gives me the equation Cs2CO3 (s) :rarrow: Cs2O (s) + CO2(g) and tells me that ΔH = +400 kJmol-1 and ΔS = +161 J molK, and therefore decomposition takes place at ≥2483K. Then in the next section it proceeds to say "However, Cs2CO3 decomposes at 883K, explain the...

    Quick question on chemical decomposition

    So I'm studying for the ACS exam which will count as my final exam in 2 weeks, and I decided to do so by taking past ACS exams. I encountered a question that I can't figure out the reasoning behind the answer, and I was hoping to get some help. This is the question word for word: "Oxygen gas...
