Yes, candle burning is a spontaneous process. A spontaneous process is defined as: once it is allowed to start, the process will proceed to the finish without any external intervention. You lit the candle, it was allowed to burn and it would keep going without any help. The Gibbs free energy change for this process is negative.
On the other hand, the decomposition of CaCO3(s) is NOT a spontaneous process. You have to keep heating the reaction vessel in order to decompose all CaCO3. Outside intervention is needed for this process to finish.
Burning is a chemical reaction with oxygen (oxidation).
Candle burning is a spontaneous reaction. It is an exothermic reaction that occurs naturally and releases heat and light energy as the wax is being oxidized in the presence of oxygen from the air.
No, the burning of paper is not a spontaneous reaction as it requires an external heat source to initiate the combustion process. Once the paper is exposed to sufficient heat, it undergoes a chemical reaction with oxygen in the air to produce heat and light energy, resulting in the flame and smoke that we observe during combustion.
The ignition of charcoal requires an external heat source to initiate the combustion reaction. Once the charcoal is ignited, the burning process becomes self-sustaining and does not require continuous external heat to sustain the reaction. This is why the burning of charcoal is considered a spontaneous process once it has been ignited.
Burning a candle is not spontaneous combustion. That is when something ignites with no outside heat source. If a candle burst into flame with no match or lighter, THAT would be spontaneous combustion.

A spontaneous process.
The reaction of breaking apart ATP and a phosphate to produce heat is an exergonic reaction. It releases energy in the form of heat. This process is spontaneous because it occurs without the need for an input of additional energy.
Francisco Candel died on November 23, 2007, in Barcelona, Barcelona, Catalonia, Spain.
your phrase "keeps burning" is unclear; someone who literally burns for no apparent cause is called "spontaneous combustion."
