They don't - they will react under very many conditions, but more extreme than the ones you mention. The reaction to form HCl has a high activation energy - provided in your example by a photon of light.
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.
Hydrogen and chloride react to form hydrogen chloride through a chemical reaction called combination or synthesis reaction. This reaction results in the formation of covalent bonds between hydrogen and chlorine atoms, producing a colorless acidic gas that dissolves in water to form hydrochloric acid.
The reaction between methane and bromine in the presence of sunlight results in the substitution of one hydrogen atom in methane with a bromine atom, yielding bromomethane (CH3Br). The equation for this reaction is: CH4 + Br2 → CH3Br + HBr.
Sunlight will degrade any hydrogen peroxide that is in the water. This is why over-the-counter hydrogen peroxide is sold in brown bottles.
Polar stratospheric clouds can convert the products of CFCs (chlorofluorocarbons) into reactive forms that contribute to ozone depletion. The chlorine released from CFC molecules in the presence of sunlight can react with ozone molecules in the stratosphere, leading to ozone destruction. This process can further exacerbate the thinning of the ozone layer.
The products formed are a mixture of mainly chloroethanes (C2H5Cl) and some hydrogen chloride (HCl) gas. The reaction of ethane with chlorine in sunlight leads to the substitution of hydrogen atoms in ethane by chlorine atoms.
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.
When methane reacts with chlorine under sunlight, it forms chloromethane and hydrogen chloride. This reaction is a substitution reaction where one or more hydrogen atoms in methane are replaced by chlorine atoms. Overall, the reaction is exothermic and can be potentially explosive.
It is a photochemical reaction; the diatomic molecule of chlorine is photochemically (under the action of photons) dissociated in chlorine radicals. Chlorine radicals react with the diatomic molecule of hydrogen to form hydrogen chloride (HCl). A radical chain reaction was initiated and is continued. For details you can read a very interesting article at the link below.
Flourine (with hydrogen, even in the cold and dark), also Chlorine (when exposed to sunlight with hydrogen)
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.
When toluene reacts with chlorine in the presence of sunlight, a substitution reaction occurs where one or more hydrogen atoms in the toluene molecule are replaced by chlorine atoms. This reaction can result in the formation of different chlorinated derivatives of toluene, such as benzyl chloride or benzal chloride, depending on the conditions and the position of the substitution on the benzene ring.
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.
When chlorine water is exposed to sunlight, it can produce a mixture of chemicals including hypochlorous acid, hydrochloric acid, and oxygen. In the presence of organic matter, additional byproducts such as chloroform and other disinfection byproducts may also form.
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.
The total residual chlorine in seawater can be affected by various factors such as sunlight exposure, temperature, pH levels, and the presence of organic matter. Sunlight can break down chlorine, leading to lower residual levels. Higher temperatures can also decrease residual chlorine, as can higher pH levels. Presence of organic matter can also consume chlorine, affecting the total residual levels in sea water.
Hypochlorous acid (HOCl) can decompose into chlorine gas (Cl2) and oxygen gas (O2) in the presence of direct sunlight.
