1. The reaction C2H4 + HBr to C2H5Br is carried out in continuous reactor. The product stream is analysed and found to contain 50 mole % C2H5Br and 33.3% Br .The feed to the reactor contains only C2H4 and HBr. Calculate the fractional conversion of limiting reactant and the percentage by which the other reactant is in excess.

i'm hoping this is like a multiple answer question. if it is then it would be, the location of the plants and also the height of the plants since one she wants to know where in her garden the chamomile grows best. but also to see which plants grew better in the location she also has to measure the plant itself. (if you can only choose one answer than it would be c).

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
