Without sunlight, chlorine in water will slowly dissipate through evaporation, reacting with organic matter or forming chloramines. This process can take longer compared to when exposed to sunlight, as the degradation of chlorine is accelerated by UV radiation.

What happens when chlorine water is exposed to sunlight?

When chlorine water is exposed to sunlight, it can undergo a reaction that produces hydrochloric acid and oxygen gas. This reaction is a form of photochemical decomposition, where the energy from sunlight breaks down the chlorine water into its constituent elements.


What happens when hydrogen reacts with chlorine in direct sunlight?

When hydrogen reacts with chlorine in direct sunlight, they combine to form hydrogen chloride gas. This reaction is highly exothermic and produces a lot of heat and light. The reaction is also photochemical, meaning it is initiated by the energy of sunlight.


What happens when benzene reacts with chlorine in bright sunlight?

When benzene reacts with chlorine in bright sunlight, substitution reactions can occur where one or more hydrogen atoms in the benzene ring are replaced by chlorine atoms, forming chlorobenzene derivatives. This process is known as chlorination and is a type of electrophilic aromatic substitution reaction.


What is the equation of methane with bromine in the absence of sunlight?

In the absence of sunlight, methane (CH4) will react with bromine (Br2) to form bromomethane (CH3Br) and hydrogen bromide (HBr) as products. The balanced chemical equation for this reaction is CH4 + Br2 -> CH3Br + HBr.


What happens when Hydrogen and chlorine react in direct sunlight?

When hydrogen and chlorine react in direct sunlight, they undergo a very rapid and exothermic reaction, forming hydrogen chloride gas. This reaction is highly explosive and can produce intense amounts of heat and light. It is important to handle these two substances carefully and prevent exposure to direct sunlight to avoid accidents.

What happens when chlorine is exposed to sunlight?

Do you mean elemental chlorine, or the "chlorine" that's used in swimming pools?Sunlight can break down swimming pool "chlorine". For that matter, it can break down elemental chlorine also, into two chlorine free radicals, which are much more reactive than elemental chlorine (which is, itself, kinda reactive). Sunlight can cause a mixture of elemental chlorine and elemental hydrogen to explode.Free radical chlorine is serious business. It's one of the prime culprits in the degradation of the Earth's ozone layer.

What happens when all 3 isotopes of hydrogen react with chlorine in sunlight?

When all three isotopes of hydrogen (protium, deuterium, and tritium) react with chlorine in sunlight, they form hydrogen chloride (HCl). The reaction involves the hydrogen atoms exchanging electrons with the chlorine atoms to form the covalent bond in hydrogen chloride. The reaction is more efficient in sunlight as it provides the energy needed to break the bonds and initiate the chemical reaction.


Why does a tree in the path of sunlight create a shadow instead of the spreading around the tree?

Light travels in straight lines and therefore some will hit the tree. Where this happens a shadow (absence of light) is created behind the tree.


Why is it better to add chlorine to a swimming pool at night?

Adding chlorine to a swimming pool at night can help it work more effectively because sunlight can break down chlorine. By adding chlorine at night, it has more time to disperse and work to kill bacteria and algae before sunlight breaks it down. Additionally, swimmers are typically not using the pool at night, reducing the risk of exposure to high chlorine levels.
