Your answer is temperament
Should be B) Antibiotic resistance is a serious global problem.<span />
<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>
Yes because when you want something to be perfect you tend to try and imagine it beforehand so you know what to do perfectly and if you mess up you can imagine punching the person who messed you up :)
