Answer:
A is the closest thing. You change the composition of the steak. You don't in any of the others.
Explanation:
Usually when you cook something, you are doing something to the composition of the object being cooked. A steak might not be obvious, but boiling an egg should be.
Chopping a tree is something physical. You are removing mass in such a way that the tree will fall. There's nothing chemical about that.
Heating a cup of tea looks like it might be chemical. After all steam is sometimes given off which looks like it is chemical. It's not. The water in the tea is just changing phase.
Drying clothes in a dryer. Again, this looks like something might have changed. After all the mass of the clothes just became less. But all you are doing is separating two masses (leaving one of them behind).
CS₂ + Cl₂<span> </span>→ CCl₄ + S₂Cl₂<span> [unbalanced equation]
</span>CS₂ + 3Cl₂ → CCl₄ + S₂Cl₂ [balanced equation]
∴ the mole ratio of Cl₂ : CCl₄ is 3 : 1 (option D)
...air filtering using materials that absorb the toxic vapors
Answer:
your answer is
isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties.
