Facts About Hydrogen - strangefacts

• The Sun is made out of 92% hydrogen, 7% helium and the rest is other low number gasses

• The odor of farts comes from small amounts of hydrogen sulfide gas and mercaptans in the mixture 

• Joseph Priestley not only discovered oxygen, but he also discovered ammonia, carbon monoxide, hydrogen chloride, sulphur dioxide, and nitrous oxide. He was also the first person to isolate chlorine

• Most people know what pH means, but few people know that it stands for pondus hydrogenii which means potential hydrogen and that each unit is a phidron

• Hydrogen is the lightest, simplest and most commonly found chemical element in the Universe, making up around 75% of its elemental mass

The pink Glowish layer in space is composed of Hydrogen

• Hydrogen is found in large amounts in giant gas planets and stars, it plays a key role in powering stars through fusion reactions

• The chemical symbol of hydrogen is H. It is an element with atomic number 1, this means that 1 proton is found in the nucleus of hydroge

• Hydrogen is commonly used in the petroleum and the chemical industries and is also widely used for many physics and engineering applications such as welding or as coolant

• Hydrogen gas is extremely flammable. It is used as a fuel by the space shuttle main engine and was associated with the famous explosion of the Hindenburg airship
• Hydrogen compounds commonly are called hydrides
  

• Hydrogen may be produced by reacting metals with acids (e.g., zinc with hydrochloric acid)

• The physical form of hydrogen at room temperature and pressure is a colorless and odorless gas

• Hydrogen has many uses, though most hydrogen is used for processing fossil fuels and in the production of ammonia
• Hydrogen peroxide is a chemical compound with the molecular formula H2O2. It is often used as a hair bleach or cleaner. At certain concentrations it can also be used to clean wounds

• Hydrogen was used for air travel from 1852 when the first hydrogen lifted airship was created by Henri Giffard. Later airships that used hydrogen were called zeppelins and while they were reliable and safe for the majority of the time their use was stopped soon after the Hindenburg disaster in 1937

• The Hindenburg airship was destroyed in a midair fire over New Jersey that was both filmed and broadcast live on radio

Facts About Oxygen - strangefacts

• The adult human body requires about 88 pounds of oxygen daily

• The grass and trees along the U.S. interstate highway system release enough oxygen to support 22 million people

• The only part of the body that has no blood supply is the cornea in the eye. It takes in oxygen directly from the air

• Oxygen-poor blood (shown in blue) flows from the body into the right atrium

• If you are locked in a sealed room, you will die of carbon dioxide poisoning before your brain starves from oxygen deprivation

• Joseph Priestley not only discovered oxygen, but he also discovered ammonia, carbon monoxide, hydrogen chloride, sulphur dioxide, and nitrous oxide. He was also the first person to isolate chlorine

• Your brain uses 20% of the total oxygen in your body

• It is thought that a yawn works to send more oxygen to the brain, therefore working to cool it down and wake it up

• The brain can live for 4 to 6 minutes without oxygen, and then it begins to die. No oxygen for 5 to 10 minutes will result in permanent brain damage

• Ted A. Batchelor, a professional stuntman endured a full-body burn without oxygen supplies for 2 min 38 sec on an island at Ledges Quarry Park, Nelson, Ohio, USA, on July 17, 2004

• Oxygen is a very reactive element that easily forms compounds such as oxides
  

• Under standard temperature and pressure conditions two oxygen atoms join to form dioxygen (O2), a colorless, tasteless and odorless gas

• Oxygen is essential to human life, it is found in the air we breathe and the water we drink (H20)

• Oxygen makes up around 21% of the air you breathe. It is also the most common element in the Earth’s crust (around 47%) and the third most common element in the Universe (but far less than hydrogen and helium, the two most common)

• Oxygen has a number of other practical uses such as smelting metal from ore, water treatment, as an oxidizer for rocket fuel and a number of other industrial, chemical and scientific applications

• Concentrated oxygen promotes fast combustion. While a spark or heat is still needed to start a fire, having concentrated oxygen near various fuels can be very dangerous

• A single tree produces approximately 260 pounds of oxygen per year. That means two mature trees can supply enough oxygen annually to support a family of four

• A runner consumes about seven quarts of oxygen while running a 100-yard dash

• Firefighters in Florida are carrying oxygen masks for saving animals from smoke inhalation

• A 50 by 50 foot turfgrass lawn (2,500 square feet) releases enough oxygen for a family of four
