Chlorine acts as a disinfectant, killing bacteria, viruses, and other pathogens, making water safe for drinking. It forms hypochlorous acid (HOCl) in water which is a strong oxidizing agent. Sedimentation and filtration remove suspended particles. Taste may be affected if excess chlorine or by-products form. Chlorine residual protects water in distribution pipes.
Explanation:
In the liver, methanol is oxidized to formaldehyde, then to formic acid, which damages the optic nerve and can cause blindness or death. Ethanol is used as an antidote by competing for the enzyme alcohol dehydrogenase.
Explanation:
The ignition temperature (or kindling temperature) is the minimum temperature to which a fuel must be heated so that it catches fire and starts burning spontaneously. A lower ignition temperature means the fuel is more highly flammable and can ignite more easily at ambient conditions.
Explanation:
Ductility is the property of metals by which they can be drawn into thin wires. Gold, silver, and copper are highly ductile. Malleability is the ability to be beaten into thin sheets. Sonority is the property of producing a ringing sound when struck. Conductivity refers to heat or electricity.
