Answer» The equation given below relate to the manufacture fo sodium carbonate (molecular weight of $N a_{2} C O_{3} = 106$ ). 1. $N a C l + N H_{3} + C O_{2} + H_{2} O \to N a H C O_{3} + N H_{4} C$ 2. $2 N a H C O_{3} \to N a_{2} C O_{3} + H_{2} O + C O_{2}$ Equations (1) and (2) are based on the production of 21.2 g of sodium carbonate. (a) What mass of sodium hydrogen carbonate must be heated to give 21.2 g of sodium carbonate? (b) To produce the mass of sodium hydrogen carbonate calculated in (a) what volume of carbon dioxide, measured at STP, would be required?
