10. a) What is the maximaum amount of iron (III) oxide than can be produced when 255 g of iron (II) sulfide arereacted with 71.4 g of oxygen gas in a closed container to produce iron (III) oxide and sulfur dioxide gas? b) What mass of the excess reactant remains after the reaction?

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

i think it is true since you can test the answer and can use observations to complete it.

where are the choice options?
