Q. What do the members of the noble gas family have in common they?
Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment. This chemical series contains helium, neon, argon, krypton, xenon, and radon.
Q. What do the members of the noble gas family have in common they are mostly chemically inert have filled outer electron configurations almost never react with other elements?
That is, noble gases are mostly chemically inert. Chemically inert, in this context, means that noble gases do not react with other elements. Noble gases are chemically inert because they have filled outer electron configurations.
Q. What happens if you breathe hydrogen?
Inhaled hydrogen gas (H2) has been shown to have significant protective effects on ischemic organs. Clinical trials abroad have shown promise that treatment of patients suffering from stroke, cardiac arrest, or heart attacks may benefit from inhaling hydrogen gas during the early recovery period.
Q. How fast can H2S kill you?
Death can occur within 1 to 4 hours of exposure. Above 500 Immediate loss of consciousness. Death is rapid, sometimes immediate. H2S levels of 100 ppm and higher are considered immediately dangerous to life and health (IDLH).
Q. Is Breathing hydrogen dangerous?
At very high concentrations in air, hydrogen is a simple asphyxiant gas because of its ability to displace oxygen and cause hypoxia (ACGIH 1991). Hydrogen has no other known toxic activity.
Q. Do we need hydrogen to breathe?
In the case of hydrogen and oxygen gas, if you react them together one way you get liquid water (H2O). The reason we cannot breathe liquid water is because the oxygen used to make the water is bound to two hydrogen atoms, and we cannot breathe the resulting liquid. The oxygen is useless to our lungs in this form.
Q. Is hydrogen harmful to humans?
Yes, hydrogen is harmful to humans. Inhalation of high concentration of hydrogen can cause asphyxiation. Asphyxiation means being deprived of oxygen, which can cause suffocation, unconsciousness and death.
Q. Is helium safe to breathe?
The more pure helium you inhale, the longer your body is without crucial oxygen. Breathing in pure helium can cause death by asphyxiation in just minutes. Inhaling helium from a pressurized tank can also cause a gas or air embolism, which is a bubble that becomes trapped in a blood vessel, blocking it.
