Answer:
The highest biogenic silica accumulation rates in this area are observed in the South Atlantic, with values as large as 53 cm. kyr−1 during the last 18,000 yr. Further, extensive biogenic silica accumulation has been recorded in the deep-sea sediments of the Bering Sea, Sea of Okhotsk, and Subarctic North Pacific.

Hey there!
The answer would be A. When electrons. move easily through objects
In science, a conductor is a material that permits a flow of energy. A material that allows the flow of charged particles is an electrical conductor. A material that enables the transfer of thermal energy is a thermal conductor or heat conductor.
Hope this helps !
Answer: A. 11.15
Explanation:
The pH of a solution is given by the formular; pH = -log [H+].
pH = - log [ 7.0 x 10 ∧-12]
= 12 - log 7
= 12 - 0.845
= 11.15
no of moles in 4 grams of H2=4/2=2
2H2+O2............2H2O
the reaction shows that 2 moles of H2 react with 1 mole of O2 to produced 2 moles H2O
now no of moles in 36grams of H2O=36/18=2
therefore he needed 1 mole of O2 to produce 36 grams of H2O and 1 mole of oxygen is equal to 32 grams of O2
