If i am not mistaken ,

density = mass / volume

density = 7.87 g/cm3
volume = 2.5 cm3

thus ,
mass = density x volume

7.87 g/cm3 x 2.5 cm3 = 19.675 g

Based on the information above, which statement provides evidence that a chemical reaction has occurred?
Vesna [10]

Answer: Atoms that make up reactants rearrange into new products

Explanation:

A chemical reaction is the process of breaking down the chemical bonds of the reacting substances  which are commonly called as reactants and making new bonds to form new substances commonly called as products.

The products will contain the same atoms as there are in the reactants but the bonds will rearrange to form different substances.

Every chemical reaction is accompanied with absorption or release of energy.
