The sample response given in the question is right.
To find the answer, we need to know more about the distance and displacement.
<h3>How distance differ from displacement?</h3>
- Displacement is the shortest distance between the initial and final points of a body.
- It is the change in position with a fixed direction.
- Displacement is a vector quantity and can be positive, negative or zero values.
- Distance is the length of actual path of the body between initial and final positions.
- It's a scalar quantity and it can be positive or zero.
- The magnitude of displacement is less than or equal to the distance travelled.
Thus, we can conclude that the given sample response is right.

Answer: The for the reaction is 212 kJ
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The net reaction is
The intermediate balanced chemical reaction will be,
(1)
(2)
(3)
Therefore, the for the reaction is 212 kJ
Substance x is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature, is mathematically given as
Q=800J.mol^{-1}
<h3>What is a graph of the other properties of x?</h3>
Generally, the equation for heat absorbed is mathematically given as
Q= Heat capacity of solid *T
In conclusion,
Q= (40)(293.15-273.15)
Q=800J.mol^{-1}
In conclusion, Because the enthalpy of fusion is 9 KJmol-1 and we are only providing 6 KJmol-1 of heat, the melting process will not be complete. the graph is attached.
