What weight of CaCO3 must be decomposed to produce a sufficient quanti – InterviewSolution

1.	What weight of CaCO3 must be decomposed to produce a sufficient quantity of carbon dioxide to convert 21.2 g of Na2CO3 completely into NaHCO3. (Molar mass of Na=23 g/mol,Ca=40 g/mol):CaCO3→CaO+CO2 Na2CO3+CO2+H2O→2NaHCO3
Answer» What weight of $C a C O_{3}$ must be decomposed to produce a sufficient quantity of carbon dioxide to convert $21.2 g$ of $N a_{2} C O_{3}$ completely into $N a H C O_{3}$ . (Molar mass of $N a = 23 g/mol, C a = 40 g/mol$ ): $C a C O_{3} \to C a O + C O_{2}$ $N a_{2} C O_{3} + C O_{2} + H_{2} O \to 2 N a H C O_{3}$
