Answer: carbon dioxide and water
Explanation:
C3H8 + 5O2 —> 3CO2 + 4H2O
A change will only occur one time in unidirectional.
Because
Cyclic : Cyclic compounds are chemical compounds having a basic non-linear structure. In other words, these are ring structures. One or more series of atoms in the compound is connected to form a ring structure.
Periodic : The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number.
Unidirectional : compound is operating or moving in one direction only and it does not move in other direction.
Bidirectional : Capable of reacting or functioning in two, usually opposite, directions.
Thus, A change will only occur one time in unidirectional.

A solute rises the boiling point of a solution, in direct relation with the number of particles added to the solution. Sucrose remains a molecule, does not separate into anything. NaCl gives Na+ + Cl-.
<span>Molar mass of sucrose is 12*12+22*1+11*16=144+22+176=342 </span>
<span>105g sucrose is 105/342=0.3moles ---> 0.3 moles of particles (molecules) </span>
<span>Molar mass of NaCl is 23+35.5=58.5 </span>
<span>35 grams of NaCl is 35/58.5=0.598 ----->0.598*2=1.1974 moles of particles (ions, Na+ and Cl-) </span>
<span>So, 35 grams of sodium chloride in 500 grams of water will have a higher boiling point</span>
