Answer: Option C. p-dichlorobenzene and 1,4-dichlorobenzene.
Explanation:
A line-angle formula with six vertices and a circle inscribed corresponds to the compound known as benzene.
Further, according to the IUPAC standards for naming benzene derivatives, you must first number the position of the substituent. In this case, the substituents (chloros) are located at the positions 1 and 4; also, for the benzene derivatives when they have 2 substituents and the positions are 1 and 4, this configuration is known as <em>para </em>or <em>p </em>configuration.
Additionally, this compound has 2 substituents (chloros) so you have to indicate this number (di).
Therefore, the correct answer is C. p-dichlorobenzene and 1,4-dichlorobenzene.

Explanation:
Chemical reaction: C + O₂ → CO₂.
Law of conservation of mass <span>states that for any </span>system closed<span> to all transfers of </span>matter<span> and </span>energy<span>, the </span>mass<span> of the system must remain constant over time.
</span><span>In </span>chemical reactions<span>, the mass of the chemical components before the reaction (in this reaction carbon and oxygen) is equal to the mass of the components after the reaction (carbon dioxide).
</span>If we use one mole of substances, that:
mass of reactants is: 12 g (C) + 2·16 g (O) = 44 g.
mass of product is: 12 g + 32 g = 44 g.
