British engineers produces 'petrol from air'

The video tutorial explains a chemical process starting with the reaction of sodium hydroxide and carbon dioxide to produce sodium carbonate. This compound is then electrolyzed to form pure carbon dioxide. Hydrogen is produced by electrolyzing water vapor. The carbon dioxide and hydrogen are mixed to synthesize methanol, which is then converted into petrol through a gasoline fuel reactor. The petrol can be stored, transported, and used as fuel.

What is the initial chemical reaction involving sodium hydroxide aimed at producing?

• Sodium bicarbonate

• Sodium sulfate

• Sodium carbonate

• Sodium chloride

What is the purpose of electrolyzing sodium carbonate in the process?

• To create hydrogen gas

• To generate pure carbon dioxide
