Can y’all help me with this last bit of my hw? I don’t really understand it and I would really appreciate it if you could help m
e.
The questions to the picture is below:
A chemist mixer two substances together: a colorless liquid with a strong strong smell and a white solid with no smell. The substances’ repeating groups of atoms are shown on the left. After they were mixed, the chemist analyzed the results and found two substances, One ending substance had the resorting group of atoms shown above on the right.
Is the ending substance the same as the colorless liquid? What happened to the atoms of the starting substances when the ending substances formed? Be sure to explain your answers to both of these questions.

Answer: 12033 kJ of heat produced per kg of formed during the combustion of benzene
Explanation:
The balanced chemical equation for combustion of benzene is :
= -6278 kJ
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
(1kg=1000g)
According to stoichiometry :
12 moles of on combustion produce heat = 6278 kJ
Thus 23 mole of on combustion produce heat =
Thus 12033 kJ of heat produced per kg of formed during the combustion of benzene
