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
Option B is a balanced equation and follows the Law of Conservation of Mass. This is because the number of atoms of each element on both sides are the same.
Answer:
0.1 M is the answer and I have explained it in the attachment below.
Hope this helped!
Answer:
A. 2
Explanation:
A particle of water is made up of two hydrogen atoms and one oxygen atom. However, the question asked for how many types of atoms there are, so the answer is 2.
