Question

Carbon monoxide gas can be separated into carbon and oxygen gas by?

Chemical methods
Applying heat
Sunlight or electric energy
None of the above.


which option is correct ​

Answer 1

The mixture of carbon monoxide and carbon dioxide can be separated by passing the mixture through water under high pressure or through concentrated NaOH solution. Also mixture can be separated by passing it through ammonical cuprous.

Answer 2

Carbon monoxide gas can be separated into carbon and oxygen gas by using sunlight or electric energy.

• To obtain carbon and oxygen from the carbon monoxide gas, electric energy is used. It is used by harnessing a source of carbon-free energy to run a reaction.
• This reaction barely not undo the process of combustion but despite that, it produces energy-rich and useful products by using carbon dioxide as an input.
• Concentrated sunlight is applied to run high-temperature thermal reactions that produces oxygen, and, carbon from carbon monoxide.
• Along with hydrogen, Carbon monoxide Is the basic chemical building block that play a role in the usage of yielding synthetic fuels. This is the reason that the process is named “sunshine to petrol.”

Hence, electric energy or sunlight is used for separating oxygen and carbon from carbon monoxide. So, the C option is correct.
