Physical change alters a given material without changing its chemical.
K and Br can form an ionic bond. Since potassium is a metal (has a small electronegativity) and bromine is a nonmetal (has a large electronegativity), potassium can give an electron to bromine creating potassium bromide.
I hope this helps. Let me know if anything is unclear.

Answer:
C6H6
Explanation:
C : 60.0 g*1 mol/12 .01g = 5.00 mol
H: 5.05 g * 1 mol/1.01 g= 5.10 mol
C:H = 5.00 mol : 5.10 mol = 1:1
CH is an empirical formula
Molar mass (12.01 +1.01)=13.02 g/mol
78.12g/mol /13.02 g/mol =6
Molecular formula is the empirical that was taken 6 times (CH)6 = C6H6
