2. A/an _______ bond allows metals to conduct electricity. A. ionic B. metallic C. covalent D. atomic
lisov135 [29]
The appropriate answer is b. A metallic bond allows metals to conduct electricity. Metallic bonds are formed by atoms of metals in which the outer electrons of the atoms from a common electron cloud. In metallic bonding the atoms are not used up in the actual bond but are shared so they are free to move about to conduct electricity. Electrons in the other bond types are held in place in the molecule an are not free to move about so they cannot conduct electricity.

Rank the following by their miscibility in
tatuchka [14]

Answer:

<h2>2. H2O < CH3OH < CH3CH2OH < C9H20</h2>

Explanation:

Decane is a hydrocarbon so it is a non-polar molecule. Non-polar molecules are soluble in non-polar molecules and polar molecules are soluble in polar molecules. Water is a polar molecule so it is least soluble in decane molecule and C_{9}H_{20} is a non-polar molecule so it is most soluble in decane molecule. Methanol and ethanol are the derivatives of hydrocarbon so they have more solubility than water but less solubility than nonane molecules.
