In milgram's experiment, compliance, or doing what the experimenter asked, dropped when: a. the study was at yale university. b. the teacher heard the learner scream. o c. the teacher and the learner were in the same room. o d. the learner stopped responding.

Option C

Explanation:

In his experiment, Milgram wanted to test the extent of obedience a person can go as per the instructions of the authority.  

In this he concluded the experiment saying that several factor when changed in the second round of experiment led to the dropping of obedience level and these factors are as follows –  

a)Conducting the experiment at some ordinary place instead of Yale university campus

b)When the teachers were asked to force the hand of learner to touch the shock plate and they were placed in the same room

c)Two participants in the same room – If one participants showed disobedience then the other participant’s disobedience level will fall automatically

d)When the authority giving instructions is not nearby or is absent

Hence, option C is correct

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
