Tantalum metal is produced by reaction of potassium heptafluorotantalate (K2TaF7) with elemental sodium (Na) in a reactor heated to 850oC. The by-products are potassium fluoride (KF) and sodium fluoride (NaF). The reactor is charged with 244.0 kg of K2TaF7 and 13.0 kg of Na. Assume that the reaction goes to completion. The reactor contents at the completion of this reaction will be the following:
Enter the number of kg of K2TaF7 remaining:
Enter the number of kg of Na remaining:
Enter the number of kg of Ta present:
Enter the number of kg of KF present:
Enter the number of kg of NaF present:
