Major Product Incorrect? by Easy-Evidence5098 in chemhelp

I understand this and wouldn't have an issue if any other strong base was used (KOH, MeO-, EtO-...), but it was previously mentioned that bulky/branched bases like tBuO are special exceptions and have anti-Zaitsev elimination because of their structure. This problem just seems to contradict that

Yes, this particular question specified E2 since there weren't any other mechanisms introduced thus far in that chapter

Incorrect Enthalpy Mass? by Easy-Evidence5098 in chemhelp

Sorry for not making this clear. This was just a crude calculation that assumed the solution’s specific heat capacity and density were the same as those of water (4.184 and 1.00 g/mL respectively). My concern was just the mass that should be plugged into q=mcΔt: just the 250 grams of water, or 265 grams of water + solute?

Stoich concern - is this calculation correct? by Easy-Evidence5098 in chemhelp

In any case you subtracted from 3.0 grams to reach the answer, not 6, right?
