Explanation

Sulphur is widely used in the chemical industry, especially in making explosives like gunpowder.

It is also used in producing sulfuric acid, which is a key industrial chemical.

Explanation

Washing soda, also known as sodium carbonate (Na₂CO₃).

It is made up of sodium (Na), carbon (C), and oxygen (O).

It is commonly used for cleaning purposes due to its ability to soften water and remove stains.

Explanation

The production of ammonia in industry, specifically through the Haber process, can be increased by raising the pressure.

Higher pressure shifts the equilibrium towards more ammonia production, though temperature and catalysts also play a role.

Explanation

• Sodium carbonate is produced by the Solvay process, also known as the ammonia-soda process.
• This process was developed by Ernest Solvay in the 1860s.
• It uses salt and limestone as the main ingredients, which are readily available and inexpensive.
• The Solvay process produces roughly three-quarters of the world's supply of sodium carbonate, with the remaining being mined from natural deposits.

Explanation

The Solvay process is an industrial process that uses limestone (CaCO3 )

to produce carbon dioxide (CO2 )

which reacts with ammonia (NH3 )

dissolved in brine (concentrated NaCl(aq)) to produce sodium carbonate.
