George brings you mystery liquid A. You carefully pour it into a graduated cylinder with water (D=1g/ml), mystery liquid B (D=6.1g/ml), and mystery liquid C (D=0.4g/ml) so that they don’t mix. You find that mystery liquid A forms a layer between mystery liquid B and water. Provide a specific density range mystery liquid A could have.

i know insulin is primary but i dont know the others im sorry

explanation:

dynamic equilibrium is the answer.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

5.6⋅10−^19  j

do you need the explaination?
