Answer:
-573.67
Explanation:
whenever energy is released in a chemical reaction, we would then expect the delta H of the reaction to be negative because the reaction is an exothermic reaction.
now we have that 2.81 moles of fuel when it combusts would releases 1612kJ of energy
thus, 1 mole will release 1612/2.81 = -573.67kJ of heat
Therefore the delta H of the reaction = -573.67 kJ/mol
U got kik?
lets talk first before we go any further
The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light.
I don't know anything sorry for inconvenience but I will be used to make a system running with artificial intelligence
It forms Carbon monoxide.
CO2 +O2⇒ CO
(Sorry not balanced)
