A proton transfer reaction can occur when a carbonyl compound is placed in an aqueous acidic solution. a. True
b. False

True

Explanation:

Proton have a positive charge. They can be seen in the nucleus of an atom and they are useful in binding of the nucleus while also attracting the electrons that are negatively charged

The statement that the proton transfer reaction occurs when the carbonyl compound is placed in aqueous acidic solution is true. After this, water and also a conjugate acid which is charged 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
