<span>Symbol- Cr
Oxidation States: 6, 3, 2, 0
Chromium is unstable in oxygen, it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below. </span>
Answer:
See below.
Explanation:
The volume increases.
This is complies with Boyles Law:
At constant temperature P1 V1 = P2 V2 where P1, P2 are the pressures before and after and V1 and V2 are the volumes before and after.
Answer: Frost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice.
Hey there !:
HF s molecule with the strongest intermolecular force
<span>HF > HI > HBr > HCl</span><span>
</span>The main factor of influence at the boiling point is the question of intermolecular forces, but not only that, the molar mass also has influence (the greater the molar mass, the greater the boiling point). Note that the only one forming hydrogen bridges is the HF, therefore the largest boiling point, iodine, bromine and chlorine have the same type of intermolecular (permanent dipole) connections as they are polar, and what will differentiate the boiling point of each one is the molar mass.
