In the commercial production of the element arsenic, arsenic (III) oxide is heated with carbon, which reduces the oxide to the metal according to the following
equation:
2As,02 + 3C + 3C0, + 4As
If 8.87 g of As, O, is used in the reaction with excess carbon and 5.21 g of arsenic
is produced, what is the percent yield?

An experimental procedure requires a 10 ml of acid to be dissolved

‘which reaction would most likely require the use of an inert electrode?
