electrolysis: some key equations to consider copper metal is purified by electrolysis. How much copper metal (in grams) could be produced from copper(II)

Describe the chemical reaction based on the chemical equation below. also, explain whether the equation is balanced.

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

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
