What is in glow sticks that make them glow?
Glow sticks contain a chemical called hydrogen peroxide and a fluorescent dye. When the glow stick is bent and the hydrogen peroxide mixes with the dye, it undergoes a chemical reaction that produces light.
What chemicals can be used to rapidly rust metal?
Chemicals such as hydrochloric acid, hydrogen peroxide, and saltwater can be used to rapidly rust metal.
How bromine react with hydrogen?
Bromine reacts with hydrogen to form hydrogen bromide (HBr). The reaction is exothermic and proceeds rapidly to give a colorless gas. The reaction can be represented as follows: Br2 + H2 -> 2HBr.
Specific gravity of hydrogen?
The specific gravity of hydrogen is 0.0696. Source: The Engineering Toolbox
Why does an explosion occur when hydrogen is added to fire?
When hydrogen is added to fire, it rapidly combusts with oxygen in the air to form water vapor. This reaction releases a large amount of energy in a short period, resulting in an explosion due to the rapid increase in temperature and pressure.
Which undergoes reduction more rapidly ester or aldehyde?
Aldehydes easily reduce to primary alcohols.
Do bigger stars use hydrogen more rapidly?
Yes, larger stars consume hydrogen at a faster rate due to their higher mass and temperature, leading to more intense nuclear fusion reactions. This results in a shorter lifespan for massive stars compared to smaller ones.

What gases oxygen nitrogen helium or hydrogen which diffuses most rapidly at twenty-five degrees centigrade?
This gas is hydrogen.
Is Hydrogen a nonreactive substance?
Hydrogen is infamous for its \high reactivity. The Hindenburg, which which used hydrogen as its buoyancy gas went down rapidly in flames due to the high reactivity of that hydrogen when it was ignited.

What type of reaction happens when potassium is placed in water?
When potassium is placed in water, it undergoes a highly exothermic reaction, producing hydrogen gas and forming potassium hydroxide (KOH) as a product. This reaction is also highly reactive and can result in the ignition of the hydrogen gas produced.
Why does hydrogen pop louder when lit if it is first mixed with air?
The pop you hears is a result of the hydrogen reaction with oxygen. When it is mixed with air, all of the hydrogen is readily in contact with oxygen, and the reaction can proceed much more rapidly.
Why is ammonia water is added to hydrogen peroxide?
Ammonia water is added to hydrogen peroxide to stabilize the hydrogen peroxide solution, preventing it from decomposing rapidly. This helps to extend the shelf life of the hydrogen peroxide solution and maintain its potency for longer periods of time.
Why does metal salt explode in in water while normal salt doesn't?
I think you might be referring to sodium metal when talking about "metal salt", sodium will explode when thrown into water as it rapidly undergoes a chemical reaction yielding hydrogen gas The metal changes a lot when it becomes sodium plus alongside chloride minus in the NaCl table salt.
