Determine the enthalpy change of the following reaction: 2kclo3 -> 2kcl + 3o2 given enthalpies: kclo3: -391.4 kj/mol o2: 0 kj/mol kcl: -436.7 kj/mol

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
