I have done this question before and even though you didn’t provide the options. I think the correct option is elements
Answer:
1.52 g/mL
Explanation:
The formula for finding the density of an object is d = m/v, or density = mass divided by volume.
Therefore, we can input the two values and solve for d.
d = 220/145
d = 44/29
d ≈ 1.52 g/mL
At its discovery, benzene was recognized to be a unique unsaturated hydrocarbon because it either failed to react, by substitution with common reagents or reacted by addition that led to reactions with alkenes.
<h3>What are unsaturated hydrocarbons?</h3>
Unsaturated hydrocarbons are the hydrocarbons which have at least on double or triple carbon to carbon bond in its molecules.
All other hydrocarbons are unsaturated except for the alkanes and the cyclic alkanes.
Benzene is an aromatic compound which has a special six-carbon ring with are resonance structure reflecting the presence of three carbon-carbon bonds in its molecules.
The common reactions of unsaturated hydrocarbons are substitution and addition reactions.
However, benzene on its discovery did not undergo any of these reactions.
In conclusion, benzene showed a difference when compared with the common unsaturated hydrocarbons as it did not undergo either substitution or addition reactions.

Since K3 is greater than 1, the reaction is thermodynamically favorable.
Data;
- FeF2 is in an acidic solution
- K2 > 1 is thermodynamically favorable
- k3 > 1 is not thermodynamically favorable
- K1<1 is not thermodynamically favorable
<h3>Hess Law</h3>
This states that the heat change in a given chemical reaction is the same irrespective of the number of process in which the reaction is effected.
Using Hess Law;
substituting this using Gibbs law,
Since K3 is greater than 1, the reaction is thermodynamically favorable.
