Elements are represented by their symbols with the first letter capitalized and the rest in lowercase. Copper is represented by Cu and Bromine is represented by Br. When combined to for a compound, the format of the symbols remain. Hence, the correct format would be CuBr.
Thus, the answer is C: CuBr<span>.</span><span />

Answer:
3.077 × 10¹⁴ Hz
Explanation:
f = ?
wavelength = 9.75 × 10-⁷m
using the formula,
c = wavelength × frequency
f = c/wavelength
but c(speed of light) = 3×10⁸m/s
f = 3 × 10⁸/9.75 × 10-⁷
f = 3.077 × 10¹⁴ s-¹
