Mass = 10.8 g
volume = 0.56 cm³
Density = mass / volume
D = 10.8 / 0.56
D = 19.29 g/cm³
Is Gold . ( Density of gold )

What is chemical reaction? </h3>
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
A change in the properties and identity of the reacting substances means that a chemical reaction has occurred.
Therefore the correct option is option C.
