Physical change is where u change physically or on the "outside" hope this helps, have a great day!
The density of the sample is:
Density = mass / volume
Density = 9.85 / 0.675
Density = 14.6 g/cm³
If the sample has 95% gold, and 5% silver, its density should be:
0.95 x 19.3 + 0.05 x 10.5
Theoretical density = 18.9 g/cm³
The difference in theoretical and actual densities is very large, making it likely that the jeweler was not telling the truth.
Hello there what is the question?
Omg that is that ( but I do not know this
It would be a,b,c as the answer. hope this helps!
