2A1 + 6HCI - 2AICI+ 3H, 1. If 12 moles of Al completely react, how many moles of H, are produced?
2. You want to make 10 moles of AICI. How many moles of HCl does that require?
3. If 85.0 grams of HCl react, how many moles of H, are produced?

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
