Question

how do you break apart a compound?
chemical bonds must be broken.
water must be added.
it must be physically separated.
the compound can be cut apart.

Explanation:

Compounds are made of elements held together by chemical bonds. To break a compound, these chemical bonds need to be broken. Adding water only works for some water - soluble compounds and is not a general method. Physical separation and cutting are for mixtures and not for breaking compounds at the chemical level.

Answer:

Chemical bonds must be broken.
