Mass is the weight of an object.



Solubility and melting point are two examples of physical properties.



Atoms that make up a compound are bonded together; they cannot be separated by physical means.



The density of an object can be calculated by dividing the object’s length by its width.





A physical property is a characteristic of matter that you cannot observe or measure without changing the identity of the matter.



Every element and compound has a unique set of properties.

Iknow #2 is d. i just need to know why

98 ! and brainliest plz ! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
