Answer:
The answer to your question is the letter D. a decomposition reaction
Explanation:
This is a brief description of the main chemical reactions.
a) A synthesis reaction is when two reactants are combined to form only one product.
b) A disynthesis reaction. I have not heard about this chemical reaction, I think it does not exist.
c) A combustion reaction is when an organic molecule reacts with oxygen to form carbon dioxide and water.
d) A decomposition reaction is when one reactant splits to form two or more products.
The final temperature = 36 °C

The balanced combustion reaction for C₆H₆
2C₆H₆(l)+15O₂(g)⇒ 12CO₂(g)+6H₂O(l) +6542 kJ
MW C₆H₆ : 78.11 g/mol
mol C₆H₆ :
Heat released for 2 mol C₆H₆ =6542 kJ, so for 1 mol
Heat transferred to water :
Q=m.c.ΔT
Explanation:
To convert moles to particles or grams to particles, let us have a firm understanding of what a mole is.
A mole is the unit of measuring quantity of particles.
It is the amount of substance that contains the Avogadro's number of particles.
The particle can be atoms, molecules, formula units, electrons, protons, neutrons, etc.
So, to convert from moles to particles;
1 mole of a substance contains 6.02 x 10²³ particles
To convert from grams to particles;
First convert to moles;
number of moles =
So, 1 mole of a substance contains 6.02 x 10²³ particles
