A 1.0 M solution of NaOH was electrolyzed for 2.0 hours using a current of 5.0 amperes. How many moles of gas were produced at the anode?

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.

Ibelieve the answer 4 moles

Naoh + hbr -> nabr (salt) + h2o ca (oh)2 + 2hbr - - - > ca (br)2 + 2h2o
