Write a paragraph explaining what would happen if liquids A, B 3,C, and D were added to the graduated cylinder. Describe how the layers of the density column would be arranged (the order they would be in). Finally, predict where an object with a density of 1.07 g/cm^ 3 would stop in the column. Justify your reasoning with quantitative data (your density calculations).

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
