Answer 1

Answer:

1.Sodium carbonate

2. sodium carbonate decahydrate

3. READ EXPLAINATION

Explanation:

1. Sodium carbonate is a chemical compound with the molecular formula\[N{a_2}C{O_3}\]. It's commonly referred to as washing soda and is used in cleaning products, glass production, as a food additive, and more.

2. sodium carbonate decahydrate. So it contains 10 water molecules.

3. When NaCl is reacted with ammonia,  carbonoxide  and oxygen, sodium hydrogen carbonate and ammonium chloride are obtained. When the obtained sodium hydrogen carbonate is heated sodium carbonate is obtained along with water and carbon-dioxide.
