Explanation:
i checked the slideshow from educere lol (slide 8 colligative properties lesson)
If I'm not mistaken, the answer should be B. Oxidation
Answer:
Percent yield = 94.62%
Explanation:
Given data:
Actual yield of BeBr₂ = 1.23 mol
Theoretical yield of BeBr₂ = 220 g
Percent yield = ?
Solution:
Theoretical yield in moles:
Number of moles = mass/molar mass
Number of moles = 220 g/168.82 g/mol
Number of moles = 1.30 mol
Percent yield:
Percent tiled = actual yield / theoretical yield × 100
by putting values,
Percent yield = 1.23 mol / 1.30 mol × 100
Percent yield = 0.9462 × 100
Percent yield = 94.62%
If the Arctic became completely ice-free and phytoplankton productivity levels were maintained, Arrigo and his colleagues calculated that the new carbon sink could in theory absorb an extra 160 million tonnes of carbon each year.
