A 38.9 mL aliquot of weak base that has a concentration of 0.562 M will be titrated with 0.37 M HCl. Calculate the pH of of the solution upon the addition of 13.77 mL of HCl. The Kb of the base is 4.5×10-6.

1.cause they have wings

2.cause they are insects

3.cause they are

explanation:

i think option no d is the correct answer

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: )
