I shall return again; I shall return To laugh and love and watch with wonder-eyes
At golden noon the forest fires burn,
Wafting their blue-black smoke to sapphire skies.
I shall return to loiter by the streams
That bathe the brown blades of the bending grasses, And realize once more my thousand dreams
Of waters rushing down the mountain passes.
I shall return to hear the fiddle and fife
Of village dances, dear delicious tunes
That stir the hidden depths of native life,
Stray melodies of dim remembered runes.
I shall return, I shall return again,
To ease my mind of long, long years of pain.

that's a very pretty poem but what's a question?

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
