Im a bit torn here, lets look at the definitions of physical and chemical changes:
physical change changes only the phase/state of a substance, but not what the substance is
chemical change is a chemical reaction where a new substance is formed and energy is given off or absorbed.
(it just started raining and it smells really nice out my window)
clearly, this cannot be just a physical reaction. i think i would be inclined to pick B. but C. could have merit as an answer too. sorry for the ambiguity x
Answer: -
Following are five examples of structures with the chemical formula C₆H₁₂
Compound A is Hexene.
Compound B is 2-Hexene.
Compound C is 3-Hexene.
Compound D is Cyclohexane.
Compound E is Methylcyclopentane.
As we can see Hexene, 2- Hexene and 3-Hexene all have double bonds.
Cyclohexane and Methylcyclopentane contains a ring.
A flight simulator that helps astronauts prepare for a shuttle launch is an example of a Scientific Model.
(does this belong in chemistry?)
