5a). Sodium reacts with excess oxygen to form sodium peroxide, Na,0,. 2Na + 02 → Na,02 Calculate the maximum mass of sodium peroxide formed when 4.60 g of sodium is burnt in excess oxygen. (A, values: Na = 23.0, 0 = 16.0) 5b). Tin oxide (IV) is reduced to tin by carbon. Carbon monoxide is also formed. Sno2 + 20 > Sn + 2C0 Calculate the mass of carbon that exactly reacts with 14.0 g of tin(IV) oxide. Give your answer to 3 significant figures. (A, values: C = 12.0,0 = 16.0, Sn =118.7)
