Answer 2

Answer:

• The chemical substance with the formula Na2CO3. 10H2O is a pure, white, dry solid particle that contains 10 water molecules bound to one sodium carbonate molecule (NaCO3).

Explanation:

• Salt carbonate is another name for washing soda.
• Since washing soda contains 10 water molecules, it is often referred to as sodium carbonate decahydrate.
• A source of sodium that is insoluble in water is sodium carbonate decahydrate, which may be easily heated to form other sodium compounds like the oxide (calcination).
• When carbonate compounds are exposed to weak acids, they also release carbon dioxide.
• When carbonate compounds are exposed to weak acids, they also release carbon dioxide.It decomposes into water and carbon dioxide gas when heated. Bubbles made of carbon dioxide are released.
