Description : The inert gas which is substituted for nitrogen in the air used by deep sea divers for Breathing is: (1) Neon (2) Argon (3) Krypton (4) Helium
Last Answer : (4) Helium Explanation: Helium is used since it has very low (almost non-existent) narcotic properties. The nitrogen in air is highly narcotic at depth and adding helium allows one to dive without the effects of narcosis (where one's mind is impaired).
Description : The inert gas which is substituted for nitrogen in the air used by deep sea divers for breathing is – (1) Neon (2) Krypton (3) Argon (4) Helium
Last Answer : (4) Helium Explanation: Helium is used by deep sea divers because it reduces the narcosis of nitrogen and it remains below the oxygen toxicity limits. In fact, they use tri mix of Oxygen, helium and a little bit of nitrogen.
Description : Which of the inert gases can form compounds? (1) Helium (2) Xenon (3) Krypton (4) Argon
Last Answer : (2) Xenon Explanation: Xenon compounds are the most numerous of the noble gas compounds that have been formed. Most of them have the xenon atom in the oxidation state of +2, +4, +6, or ... such as fluorine or oxygen. Some of these compounds have found use in chemical synthesis as oxidizing agents.
Description : The most abundant element in the earth's atmosphere is – (1) Argon (2) Nitrogen (3) Oxygen (4) Krypton
Last Answer : (2) Nitrogen Explanation: The most abundant gas in the Earth's atmosphere is nitrogen. Nitrogen makes up 78 percent of the Earth's atmosphere, and it is a permanent gas, which means that its percentage ... atmosphere is made up of 21 percent oxygen, 0.9 percent argon and 0.1 percent trace gases.
Description : Which among the following is used to dilute oxygen in the gas cylinders used by divers? (1) Krypton (2) Argon (3) Helium (4) Neon
Last Answer : (3) Helium Explanation: Helium is used to dilute the oxygen and nitrogen to reduce these affects. Helium is the gas of choice to use because it is an inert gas, is thinner, therefore more compressible than air, and its narcotic properties are negligible in comparison to nitrogen.
Description : The inert gas which is substituted for nitrogen in the air used by deep sea divers for breathing, is - (1) Xenon (2) Krypton (3) Argon (4) Helium
Last Answer : (4) Helium Explanation: Trimix is a breathing gas, consisting of oxygen, helium and nitrogen, and is often used in deep commercial diving. The helium is included as a substitute for some ... possible to create mixes suitable for different depths or purposes by adjusting the proportions of each gas.
Description : Which one of the following noble gases is not found in the atmosphere? (1) Argon (2) Krypton (3) Radon (4) Xenon
Last Answer : (3) Radon Explanation: All the noble gases are present in Earth's atmosphere and, except for helium and radon, their major commercial source is the air, from which they are obtained by liquefaction and fractional distillation.
Description : An inert gas mixed with oxygen given to patients suffering from restricted breathing is – (1) Helium (2) Krypton (3) Radon (4) Argon
Last Answer : (1) Helium Explanation: Heliox is a breathing has composed of a mixture of helium (He) and oxygen (O2). Heliox has been used medically since the 1930s, and although the medical community adopted ... its range of medical uses has since expanded greatly, mostly because of the low density of the gas
Description : Which gas is used in filling electric bulbs - (1) Neon (2) Argon (3) Krypton (4) Radon
Last Answer : (2) Argon Explanation: Argon is used to fill incandescent light bulbs to inhibit the evaporation of the tungsten filaments and increase bulb life.
