Answer:
In the reaction ocurrs a nucleophilic substitution of a primary alkyl bromide, where the nucleophile is CH3O-.
Explanation:
Nucleophilic substitution is a type of substitution reaction in which a nucleophile replaces an atom or group in an electrophilic position of a molecule, called a leaving group.
It is a type of fundamental reaction in organic chemistry, where the reaction occurs on an electrophilic carbon. Although nucleophilic substitution reactions can also take place on covalent inorganic compounds.
Answer:
Group 17, 2, 7, 7 electrons
Explanation:
That’s a dumb question, because It depends on the experiment. I would guess “a” or “d” because in most cases running out of time during a lab, or getting impatient, etc can give you a lower yield.
Unless I’m misreading “d”, it just seems like a more in-depth version of “a”. So it wouldn’t hurt to try that one.

Answer:
a. The new pressure is 606,25 Torr.
b. -243,9°C is needed to reach the pressure of 7250 Torr.
Explanation:
Gay Lussac's law for gases says that if the volume in a gas remains constant, the pressure will be directly proportional to the temperature change.
P1 . T1 = P2. T2
(Temperature must be in K)
725 Torr . 291 K = P2 . 348 K
(725 Torr . 291 K) /348 K = P2
606,25 Torr = P2
725 Torr . 291K = 7250 Torr . T2
(725 Torr . 291K) /7250 Torr = T2
29,1 K = T2
T° K - 273 = T°C
29,1 K -273 = -243,9°C
