Hi,
your answer would be false. But it seems you already knew that.
I hoped I helped and if you need help you could always ask me :)

Step 1:
Divide mass of each element with its M.mass in order to find out moles.
C = 63.2 g / 12 g/mol = Moles = 5.26 moles
H = 5.26 g / 1.008 g/mol = Moles = 5.21 moles
C = 41.6 g / 16 g/mol = Moles = 2.6 moles
Step 2:
Select moles of the element with least value and divide all moles of element by it,
C H O
5.26/2.6 : 5.21/2.6 : 2.6/2.6
2.02 : 2.00 : 1
Result:
Empirical Formula = C₂H₂O
Answer:
<u>Physical Change</u>
Explanation:
Its a physical change because it is not changing its molecular structure it is only changing the shape of the shale.
