Refer to the titration curve found in question 1 of the Pre-Laboratory Questions in your lab notebook. 1.802 grams of KHP is dissolved in 20.0 mL of distilled water. The titration curve given is for the titration of the KHP solution with NaOH. See Eq. 5 in your lab manual for the balanced equation for the reaction. Determine the number of moles of KHP in the solution.

alfred von schlieffen, german army chief of staff, was given instructions to devise a strategy that would be able to counter a joint attack. in december, 1905, he began circulating what later became known as the schlieffen plan. schlieffen argued that if war took place it was vital that france was speedily defeated.

i dont know the answe

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

0.88m hope i am correct : )
