Answer:
The correct answer is option C, areas with a high salinity
Explanation:
The higher the density of the ocean water, the lower will be the temperature. The highly saline ocean water thus exists in the polar regions than the tropic regions. Due to high density the cold water seeps down and thus it further becomes cooler while a low density ocean water remains at the surface and possess additional heat
Answer:
Percentage recovery of acetylferrocene = 81.6%
Explanation:
Mass of the sample mixture = 22.092 g
Ratio of mixture of acetylferrocene and ferrocene = 1 : 1
This means that the sample conatains equal amounts of acetylferrocene and ferrocene.
Therefore the mass of each sample in the mixture = 22.092 g / 2 = 11.046 g
Mass of acetylferrocene recovered = 9.017 g
Percentage recovery of acetylferrocene = (mass of recovered/ mass in sample) * 100%
Percentage recovery of acetylferrocene = (9.017 g / 11.046 g) *100%
Percentage recovery of acetylferrocene = 81.6%
