Answer:
(a) Barium is produced at the negative electrode
(b) Iodine is produced at the positive electrode
Explanation:
When an electric current is passed through a solution containing electrolyte, a non spontaneous reaction is stimulated. This results in the flow of <u>positively charged ions to negatively charged electrodes(</u><u>cathode</u><u>) and negatively charged ions to positively charged electrodes(</u><u>anode</u><u>)</u>
When an electric current is passed through molten 
in the electrolytic cell, the following reactions takes place:
→ 
+ 2
At the anode;
Iodine ions will lose an electron and will be oxidized to iodine
→ 
+ 
At the cathode;
Barium ions gains electrons and its reduced to barium metal
+ 
→ Ba

Marie curie worked as a governess and she was awarded noble prize for her discoveries.
Explanation:
When Marie curie worked as a governess for three years her employer allowed her to teach reading to the children of peasant workers at his beet sugar factory. This was banned under Russian rule. During that time she studied chemistry lessons from her father by mail.
Marie curie was awarded the Noble prize in chemistry for her discoveries and studies of elements radium and polonium. She is the only women who is awarded the Noble prize twice.
She made her first research into the treatment of tumors with radiation and founded a Curie institutes, that are important medical research centers.
It means it's the anion or the negatively charged atom
Answer:
its orginal charge is none then through the reaction it is reduced because then final charge is -1 meaning is went down 1 so its charge was reduced
Hope this helps! :)
