I believe the best description comparing the structure of carbohydrates and nucleic acids would be A.
Answer:
4.44 dm³ of SO₂
Solution:
The balance chemical equation is as follow,
CS₂ + 3 O₂ → CO₂ + 2 SO₂
According to equation,
22.4 dm³ (1 mole) CS₂ produces = 44.8 dm³ (2 mole) of SO₂
So,
2.22 dm³ CS₂ will produce = X dm³ of SO₂
Solving for X,
X = (2.22 dm³ × 44.8 dm³) ÷ 22.4 dm³
X = 4.44 dm³ of SO₂
Answer:
25.0%
A solution of benzene (C6H6) and toluene (C7H8) is 25.0% benzene by mass. At 25 °C the vapor pressures of pure benzene and pure toluene are 94.2 torr and 28.4 torr, respectively.
H3O4 is your answer but u should use your chart
