How many representative particles are in 11.5 moles Ag?

24 silver atoms.

Explanation:

11.5 moles of silver atoms will have = 11.5×6.022×1023=6.925×1024 11.5 × 6.022 × 10 23 = 6.925 × 10 24 silver atoms.

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
