To determine the gas commonly used in burners in a laboratory setting, let's briefly examine the options provided:

1. Coal Gas: This is a mixture of gases that is produced from burning coal. While historically significant, it is less common in modern laboratory settings due to safety concerns and the availability of cleaner energy sources.

2. Oil Gas: This gas is obtained from the vaporization of oil and is also not widely used in laboratories for burner applications.

3. Water Gas: Water gas is produced by passing steam over hot carbon. It typically consists of carbon monoxide and hydrogen, and while it has applications in certain industrial processes, it is not commonly used for laboratory burners.

4. Producer Gas: This gas is generated by the combustion of carbonaceous materials. It mainly consists of hydrogen, carbon monoxide, and some carbon dioxide. Producer gas is often used in industrial applications but is not the standard for laboratory burners.

Conclusion

The most commonly used gas for laboratory burners, especially in educational settings or research, is B) Oil gas. This gas is preferred due to its cleaner combustion properties compared to coal and producer gases, making it safer for laboratory use.
