B. Keq
= 1.0 x 100
=
C. Keq = 1.0 10
D. Keq = 1.0 100

the ratio of the conjugate base to the acid required to attain the desired ph.

b) nuclear ive learned that in a pedtrodic table

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
