Is hydrogen toxic?

NO. Hydrogen gas is non-toxic. However, it can displace oxygen (and if hot enough burn in it) and thus can be an asphynxant in large quantities. But hydrogen by it self is not toxic at all.


Which is More toxic to humans inorganic Mercury or methyl Mercury?

Methyl mercury is more toxic to humans than inorganic mercury. Methyl mercury is a highly toxic organic form that can accumulate in living organisms and bioaccumulate in the food chain, leading to potential health risks when consumed by humans. Inorganic mercury compounds are generally less toxic and less likely to bioaccumulate.


Is hydrogen poisonous?

Hydrogen gas itself is not poisonous, as it is a naturally occurring element and is non-toxic. However, hydrogen can be dangerous if it is in high concentrations in the air because it is highly flammable and can displace oxygen, leading to a potential risk of asphyxiation.


What is difference between hydrogen sulfide and hydrogen sulphide?

There is no difference between hydrogen sulfide and hydrogen sulphide. The term "sulfide" and "sulphide" both refer to the chemical compound H2S, also known as hydrogen sulfide. The difference in spelling is simply a matter of regional or historical variation.


How is hydrogen gas react with sulfur?

When hydrogen gas reacts with sulfur, it forms hydrogen sulfide gas (H2S) according to the chemical equation: H2 + S -> H2S. This reaction is exothermic and produces a foul-smelling gas that is toxic in high concentrations.

Do toxic chemicals help bacteria to grow?

The question is toxic to what. Not all chemicals which are toxic to humans are toxic to bacteria, and some chemicals which are toxic to bacteria are harmless to humans (which is why we can have antibiotics). There are chemicals (like Hydrogen Sulfide) which are very toxic to mammals that SOME bacteria eat as food. But there are other chemicals like chlorine which are toxic to both humans and bacteria. So the question does not have a simple answer.
