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.

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?
Spontaneous
Is the burning of paper a spontaneous reaction?
If you hold a match to the paper, then yes, the reaction is spontaneous.
What are some example of non spontaneous process?
electrolysis, burning/combustion, photosynthesis. sorry that's the processes i am sure of. (we were still discussing about this in class)

When did Francesc Candel Tortajada die?
Francesc Candel Tortajada died in 2007.
When was Francesc Candel Tortajada born?
Francesc Candel Tortajada was born in 1925.
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.
What has the author Javier Lorenzo Candel written?
Javier Lorenzo Candel has written: 'Ecosistemas'
The burning of charcoal is a spontaneous process yet heat must first be applied to start a charcoal why?
Burning charcoal is spontaneous, but not at room temperature. To start the combustion energy must be added (in the form of heat). Once the temperature of the charcoal reaches a certain temperature it reacts exothermically and releases heat. This heat of reaction is sufficient to locally heat more charcoal so that it burns continuously.
Is crystallisation of sucrose from a solution a spontaneous process?
Yes it is.
What is a name for a person who keeps burning?
your phrase "keeps burning" is unclear; someone who literally burns for no apparent cause is called "spontaneous combustion."
