A flask contains the liquids trichloromethane (chloroform) and water. They are separated using a separating funnel, which conclusion can be made from this observation alone? A. Trichloromethane and water have different relative molecular masses

B. Trichloromethane and water have different boiling points

C. Trichloromethane has a higher density than water

D. Trichloromethane is more volatile than water

E. Trichloromethane and water do not mix

law of conservation of matter

you gotta add the following molecules so we can give u an answer

explanation:

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
