The geometric arrangement of one of two or more compounds that have the same number and type of atoms but differ drastically from one another.
<h3>What is structural isomers?</h3>The term "structural isomer," also known as a "constitutional isomer," refers to a group of two or more organic compounds that share the same chemical formula but have different structures. In spite of having the identical chemical formula, the two molecules below differ in where the methyl group is located.
The most extreme kind of isomerism is structural isomerism. As contrast to stereoisomerism, which merely differs in the relative spatial arrangement of the atoms while maintaining the identical atoms and bonding structure. The enantiomers, which have molecules that are mirror images of one another, and the cis and trans forms of 2-butene are examples of the latter.
Skeletal isomers, positional isomers (also known as regioisomers), functional isomers, tautomers, and structural topoisomers are some of the different classes of structural isomers.

Answer:
Explanation:
This is a problem in calorimetry — the measurement of the quantities of heat that flow from one object to another.
It is based on the Law of Conservation of Energy — Energy can be transformed from one type to another, but it cannot be destroyed or created.
If heat flows out of the reactor (negative), the same amount of heat must flow into the water (positive).
Since there is no change in total energy,
heat₁ + heat₂ = 0
The symbol for the quantity of heat transferred is q, so we can rewrite the word equation as
q₁ + q₂ = 0
The formula for the heat absorbed or released by an object is
q = mCΔT, where
m = the mass of the sample
C = the specific heat capacity of the sample, and
ΔT = T_f - T_i = the change in temperature
1. Equation
There are two heat flows in this problem,
heat released by reactor + heat absorbed by water = 0
q₁ + q₂ = 0
q₁ + m₂C₂ΔT₂ = 0
2. Data:
q₁ = -23 746 kJ
m₂ = ?; C₂ = 4.184 J°C⁻¹g⁻¹; T_f = 95 °C; T_i = 10 °C
3. Calculations
(a) Convert kilojoules to joules
(b) ΔT
ΔT₂ = T_f - T_i = 95 °C - 10 °C = 85 °C
(c) m₂
