Answer:
a new discover a new theory
Both in the phase of a liquid & has similar qualities like both molecules.
C + 2S → CS2 + 89.3 kJ
Moles of CS2 = 150.0 kJ x (1 mol CS2/89.3 kJ) = 1.680 mol CS2
MW of CS2 = (12.01 + 2x32.06) g/mol = 76.13 g/mol
Mass of CS2 = 1.680 mol CS2 × (76.13 g CS2/1 mol CS2) = 128 g CS2
Answer:
It would be the last one because the way earth is tilted the sun rays would be pointing at the Northern Hemisphere more than the Southern Hemisphere
