Iron is obtained by reducing iron (iii) oxide using the gas carbon monoxide. the reaction is
fe2o3 + 3co > 2fe + 3co2
a. write a word equation for the reaction
b. what is the formular mass of iron iii oxide? (fe 56, o 16)
c. how many moles of fe2o3 are there in 320 kg iron iii oxide
d. how many moles of fe are obtained from 1 moles of fe2o3
e. from c and d, how many moles of iron are obtained from 320kg of iron iii oxide
f. how many iron in kg is obtained from 320kg of iron iii oxide?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
