Answer:
A)Chlorine and Bromine:
They are both non metal hence they form a covalent bond due to covalent bonding.
B)Potassium and Helium:
Helium ion has a small cationic radius and distorted by the potassium ion due to polarization.
C)Sodium and Lithium:
Both are metals hence they form a metallic bond since they share electrons to the electron cloud.
Answer:
chlorine dioxide is empirical formula for CLO2.
B. Who, what, when, where, why, and how. Those are the most important and key componants in a story.
Frequency = speed of light/ wavelength of photon. wavelength = speed of light/frequency = 3 x 10^8 / 2.43 x 10^8= 1.23m
Density = 968 g/cm³
mass = 250 g
Volume = ?
Therefore:
D = m / V
968 = 250 / V
V = 250 / 968 => 0.26 cm³
Answer C
