 There is a time delay of almost two to three minutes before the reaction proceeds because of the following processes:

<span>1)    </span><span> The acid starts to go yellow as the dehydration begins.</span>

<span>2)    </span><span> The rate of dehydration then accelerates as the acid heats up because the reaction is exothermic/chemical (releases energy by light or heat).  As the sugar molecules are stripped of water, the heat generated turns the water into steam which then expands the remaining carbon into a porous, smoking, black column.</span>

<span>3)    </span>This expands out of the reaction vessel, producing a choking acrid vapor and the smell of burned sugar.

<span> At this stage, sulfuric acid is highly corrosive and will burn skin so one must avoid contact with it. </span>

The answer to your question would more than likely be chemical energy, natural gas, and chemical energy. but I don't know what grade your in I'm in eighth if your below I know the answer. I'm pretty sure I had a question exactly like this last year but that was last year so if it's wrong sorry. I looked it up on Google to make sure
