Select all the statements that correctly describe the relative rates of the reactions described below. (I) Sec-butyl bromide reacts faster than isobutyl bromide in aqueous formic acid. (II) 1-Chlorobutane reacts slower with sodium acetate in acetic acid than with sodium methoxide in methanol. (III) 1-Chloropentane is more reactive with NaI in acetone than its constitutional isomer 1-chloro-2-methylbutane. Question 8 options: I and II I and III II and III I, II, and III
A hot air balloon is filled with air to a volume of 4.00x10^3 meters cubed at 745 degrees celcius. the air in the ablloon is then heated to 62 degrees celcius, causing the balloon to expand to a volume of 4.20x10^3 meters cubed.
