Jenny had 50 g of canola oil and 63 g of olive oil stored at room temp (20*c). She wondered Does the type of cooking oil affect how much thermal energy it takes to raise the temp of the oil? She created the follow hypothesis : If both canola oil and olivia oil are at the same temp (20* C) Then they would need the same amount of thermal energy to raise the temp to the same final temp (60* C) Do you agree or disagree with jennys hypothesis provide a reason to support your decision

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

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
