We're given the [OH⁻] as 8.34 × 10⁻¹² M. Using the formula pOH = -log[OH⁻], the pOH of this solution would be -log(8.34 × 10⁻¹²) ≈ 11.08.
The pOH is, for lack of a better term, the "opposite" of pH: A pOH of 7 is neutral; a pOH less than 7 is <em>basic</em>; and a pOH greater than 7 is <em>acidic</em>.
This follows from the relation, pH + pOH = 14. In this case, with a pOH of 11.08, our pH would be 14 - 11.08 = 2.92, which is acidic (pH < 7).
Thus, the correct answer choice is B.
<span>First you have to plug the radius (28.9 cm) in the equation for volume, so you would have V = (4/3)*pi*(28.9)^3(which means cubed) to get 101107.2126 cm^3 for volume, next use that in the formula m = d*V = 19.3g/cm^3 * 101107.2126 to get 1,951,369.203g to convert to pounds you multiply that by 0.00220462262 or 0.002 for short to get 4,302.03 pounds

Answer:
Tin
Explanation:
Tin is an element which belongs to the carbon family in the periodic table. It lies in group 14 of the periodic table i.e. IV a.
The symbol of Tin is Sn. Tin has 50 electron in total. Its atomic number is 50. The 50 electrons of tin are divided in its five energy shells. The outer most or the valence shell contains 4 electrons in the ground state.
The number of electrons present per shell in tin is : 2, 8, 18, 18, 4.
The electronic configuration of tin is : [Kr] 4d¹⁰5s²5p²
