Why does chlorine react vigorously with hydrogen in the presence of the sunlight?
Chlorine reacts vigorously with hydrogen in the presence of sunlight due to the energy provided by ultraviolet light, which initiates the reaction by breaking the Cl-Cl bond in chlorine molecules. This creates reactive chlorine atoms that can then react with hydrogen to form hydrogen chloride (HCl). The process is exothermic, releasing energy and often resulting in a rapid, explosive reaction. The presence of light accelerates the reaction by providing the necessary activation energy for the bond-breaking process.
Why do hydrogen combines with chlorine in sunlight?
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.
Is the reaction between between hydrogen peroxide and yeast an endothermic or exothermic reaction?
The reaction between hydrogen peroxide and yeast is an exothermic reaction, meaning it releases energy in the form of heat. This is because the breaking of bonds in hydrogen peroxide releases more energy than is required to form new bonds in the products of the reaction.
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
What substances form from the reaction of hydrogen and chlorine gas?
The compound hydrogen chloride, with formula HCl.
Is the reaction of hydrogen are exothermic or endothermic?
A hydrogen reaction is a release of energy, therefore is defined as exothermic.
Hydrogen and chlorine combine to produce hydrochloric acid as shown in the equation below H2 C12 - 2HC1 is this reaction exothermic or endothermic?
The reaction between hydrogen and chlorine to form hydrochloric acid is exothermic, meaning it releases heat as it proceeds. This can be inferred from the fact that the products have lower energy than the reactants, resulting in a release of energy in the form of heat.
What happens when chlorine and hydrogen peroxide react with each other?
When chlorine and hydrogen peroxide react, they form hydrochloric acid and oxygen gas. This reaction is exothermic, meaning it releases heat energy.
Hydrogen plus chlorine hydrogen chloride?
Hydrogen gas (H2) and chlorine gas (Cl2) react to form hydrogen chloride gas (HCl) in a chemical reaction that involves the sharing of electrons between the hydrogen and chlorine atoms. This reaction is highly exothermic, releasing a significant amount of heat energy. Hydrogen chloride is a strong acid when dissolved in water.
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.
If you add hydrogen chlorine what do you get?
When hydrogen and chlorine combine, they form hydrochloric acid (HCl), a strong acid that is commonly used in industrial and laboratory settings. This reaction is exothermic and releases energy in the form of heat.
What would happen when methane react with chlorine?
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.
Is the combustion of hydrogen exothermic or endothermic?
The combustion of hydrogen is exothermic because it releases energy in the form of heat and light during the reaction.
What is the word equation to show the reaction of chlorine and hydrogen?
The elements chlorine and hydrogen react with each another to form the compound hydrogen chloride.

Hydrogen and chlorine react?
Hydrogen and chlorine react to form hydrogen chloride gas, which is an acidic gas. This reaction is highly exothermic and releases a large amount of heat energy. It is a rapid reaction that produces a pop sound when carried out in a test tube.
Why does liver and hydrogen peroxide exothermic?
Hydrogen peroxide is an oxidising agent, and oxidation is an exothermic reaction. The liver is being oxidised.
