PLEASE HELP, ITS FOR A VERY IMPORTANT TEST 15 PTS A concept map for four types of intermolecular forces and a certain type of bond is shown. Compare the relative strength of the two forces C and D. Explain how you determined this comparison by identifying the forces.

Compare the relative strength of the two forces C and D. Explain how you determined this comparison by identifying the forces.

the answer is c.the valence of the atoms combine .

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
