Question
Transcribed Image Text:A sample of manganes reacts completely with oxygen in a specialized crucible. The reaction is given
as:
manganese
+
охygen
mangenese oxide
You are asked to determine the charge on manganese in the manganese oxide. Manganese can have
many different charges as an ion: +3, +4, +5, +6, or +7.
The data from your experiment is given below
8.856 g
9.902 g
10.816 g
Mass of crucible
Mass of crucible + manganese
Mass of crucible + unknown manganese oxide
Use the data provided to determine the charge on the manganese.
Finally, write a balanced chemical equation for the reaction that occurs between manganese and
oxygen in the crucible.
