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.

BlakeNo, burning a candle is not a spontaneous process because it requires the input of external energy, such as a match or lighter, to ignite the wick and sustain the combustion reaction that produces the flame. Spontaneous processes occur without the need for external intervention.

Why is a burning candel a chemical change and not a physical changes?
Burning is a chemical reaction with oxygen (oxidation).
Is candle burning a spontaneous or non spontaneous reaction?
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.
Is the burning of paper a spontaneous reaction?
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 burning of charcoal is a spontaneous process yet heat must first be applied to start a charcoal why?
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.
When you burn a candle what is spontaneous combustion?
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.
