I need this ASAP Plz What is the theoretical yield of a reaction?
A. The amount of product that is possible in a reaction
B. The amount of product obtained minus the amount possible
C.
The amount of product obtained
amount possible
D. The amount of product actually obtained in a reaction

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the answer is c

tell me if wrong

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
