Answer:

D. 3.04 × 10^-19 J

Explanation:

c = lambda * nunu = c/lambda

E = h* nu

E = h * c/lambda = 6.626x10^-34 J-sec * 3x10^8 m/sec / 6.54x10^-7 m

E = 3.04x10^-19 J

What occurs when potassium reacts with chlorine to form potassium chloride
nordsb [41]
Basically since potassium chloride is an ionic compound as it consists of a metal and a nonmetal, the potassium atom will donate one of its valence electrons to chlorine that will accept it and as a result produce oppositely charged ions, where the K + ion and the Cl - ion will attract forming an ionic bond. The compound that results is potassium chloride.
