La molécula de O3 (ozono) tiene un ángulo de enlace de 116o aproximadamente y los datos experimentales demuestran que la distancia de enlace entre los átomos de O es intermedia entre los valores teóricos de 148 pm para un simple enlace y 110 pm para un doble enlace. Represente las posibles estructuras de Lewis.
Justifique teóricamente su existencia por el cálculo de las cargas formales.​

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
