Calculate molar solubility of mg(oh)2 (ksp 1.8x10-11) in water. what is the ph of this solution? 25 pt] a) ex b) in 0.010 m mgcl2. a voltaic cell is formed by combination of two electrodes:

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
