Write the equation: 1) C – CO2 – Na2CO3 – NaHCO3 – NA2CO3 – Na2CO3 * 10H2O;

Write the equation: 1) C – CO2 – Na2CO3 – NaHCO3 -NA2CO3 – Na2CO3 * 10H2O; 2) C – CaC2 – C2H2 – CO2 – MgCo3 – Mg (HCO3) 2

Let us write down the equations for the transformation chains:
1. С + О2 = СО2 – the reaction of the compound;
1.1. 2NaOH + CO2 = Na2CO3 + H2O – ion exchange;
1.2. Na2CO3 + CO2 + H2O = 2NaHCO3 – ion exchange;
1.3. NAHCO3 + NaOH (conc.) = Na2CO3 + H2O – ion exchange;
1.4. Na2CO3 + 10H2O = Na2CO3 * 10H2O – formation of crystalline hydrate;
These reactions show the bond between carbon, its oxide and salts.
2. 2C + Ca = CaC2 – compounds;
2.1. CaC2 + 2H2O = Ca (OH) 2 + C2H2 – hydration;
2.2. 2С2Н2 + 5О2 = 4СО2 + 2Н2О – combustion reaction;
2.3. Mg (OH) 2 + CO2 = MgCO3 + H2O – ion exchange;
2.4. MgCO3 + CO2 + H2O = Mg (HCO3) 2 – ion exchange.
Reactions confirm the connection of inorganic substances with organic ones.
