Chemical property of the substance but then again it could be physical
Answer:
B.
Explanation:
Most metals can be drawn into a wire while nonmetals would break apart.
It's made up of two different metals bonded together, which expand by different amounts as they heat up. As the temperature changes, the bimetallic strip curves more or less tightly (contracts or expands) and the pointer, attached to it, moves up or down the scale.
The definition of a Lewis acid and base is: Acid is any substance that can accept a pair of nonbonding electrons, while that a Base is a species that contains a nonbonding pair of electrons, and in the reaction in the question:
SO3 + H2O -> H2SO3 + 2 OH-
We have SO3 as the conjugate base of the acid H2SO3 and H2O is acting as an acid in this occasion, therefore the answer is Acid
Cars still largely rely on oil so the answer is b
