Question

Na→NaOH→Na2 CO3→NaHCO3

Answer 1

Ответ:

2Na+2H2O=2NaOH+H2

2NaOH+CO2=Na2CO3+H2O

Na2CO3+H2O+CO2=2NaHCO3

Answer 2

It looks like you've listed a series of chemical reactions involving sodium (Na) and different compounds. Let's break down each step of the reactions you've mentioned:

1. Na → NaOH: This step likely involves the reaction of sodium (Na) with water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2):

   2Na + 2H2O → 2NaOH + H2

2. NaOH → Na2CO3: This step involves the reaction of sodium hydroxide (NaOH) with carbon dioxide (CO2) to produce sodium carbonate (Na2CO3), water (H2O), and heat:

   2NaOH + CO2 → Na2CO3 + H2O

3. Na2CO3 → NaHCO3: This step involves the reaction of sodium carbonate (Na2CO3) with carbon dioxide (CO2) to produce sodium bicarbonate (NaHCO3), also known as baking soda:

   Na2CO3 + CO2 + H2O → 2NaHCO3

Each of these steps represents a chemical reaction where different substances are reacting to produce new compounds. These reactions might occur under specific conditions such as temperature and pressure, and they are often used in various industrial processes and laboratory settings. If you have any specific questions about these reactions or their applications, feel free to ask!
