PLEASE HELP An electrochemical cell has the same following standard cell notation. Mg(s) | Mg2 || Ag+(aw) | Ag(s)

What is the standard potential for the cell?

Is this a spontaneous of non spontaneous reaction? Explain your answer

Is this a galvanic cell or an electrolytic ce? explain your answer

Thank you!!

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

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.

In the experiment you asked to react hydrochloric acid and with sodium hydroxide. when measuring the volume of the reactants, which instrument would give the greatest precision.
