Why lead is used in petrol?

-Tetraethyl lead provides octane to gasoline, thereby preventing engine knock. There are other octane providers, such as benzene and ethanol, but due to low production cost, lead is more preferred. It is added to petrol to make it burn smoothly in motor vehicles. Therefore, lead compound is added to petrol.

How do fumigants act on stored grain How do we use ethylene dibromide?

Explanation: Answer. Answer:Fumigation is a method of pest control that completely fills an area with gaseous pesticides—or fumigants—to suffocate or poison the pests within. This method also affects the structure itself, affecting pests that inhabit the physical structure, such as woodborers and drywood termites.

The opening and closing of the spiracles are under muscular control.

Is dibromoethane a gas?

It is a dense colorless liquid with a faint sweet odor, detectable at 10 ppm, is a widely used and sometimes-controversial fumigant. The combustion of 1,2-dibromoethane produces hydrogen bromide gas that is significantly corrosive….1,2-Dibromoethane.
