<span>This problem is solved by the law of effusion, which states that the rate of effusion is ~ 1/sqrt(molecular weight). Calculate the molecular weights of the different gases:
HBr = 80.91 g/mol
NO2 = 46.0055 g/mol
C2H6 = 30.07 g/mol
Thus, the approximate relative rates are HBr ~ 0.112, NO2 = 0.1474 and C2H6 = 0.1824.
Answer: C2H6 effuses fastest.</span>

Answer: People will let their guard down and not take precautions to prevent the spread of the Zika virus.
Explanation:
Answer: The water will pass from 10% glucose to 75% glucose.
Explanation:
concentration wise, the solution from higher concentration will move towards the lower concentration.75% glucose has 75 of glucose and 25 of water similarly 10% glucose has 10 of glucose but 90 of water and as a result the glucose cannot pass but the water will pass from 90 towards 25.the movement may continue till the concentration of water on either sides becomes equal.
