Explanation: Method 1 Many chemists use the Hill system for writing chemical formulas, There are two rules: If the molecule contains carbon, the elements are listed in the order C, then H, then all the other elements in alphabetical order.
If there is no carbon, all the elements are listed alphabetically. This gives us formulas like CH4 and H2O. See: Mole unit. Water may be a basic requirement for life on Earth, but the compound is far from simple. Although a single molecule of water is composed of one atom of oxygen bonded to two hydrogen atoms H2O , a collection of purely H2O molecules exists only as a gas. A water molecule has three atoms: two hydrogen H atoms and one oxygen O atom. In the case of h2o hydrogen is more electropositive than oxygen, therefore, we write the chemical formula as h2o but not as oh2.
OH, or hydroxide, group. Nonmetal hydroxides, such as hypochlorous acid HOCl , are acids. In most cases, when OH bonds to another ion the oxygen is the one that bonds to the other ion. HO is a molecule containing positive Hydrogen Oxygen atoms i. While, OH is a molecule containing negative Hydrogen Oxygen atoms i. Both are acceptable and the only difference is about the charge on oxygen. CH3-OH is written the way it is, so that you can indicate that the bond between the methyl carbon and the -OH group happens to be through the oxygen, and not the hydrogen.
So, therefore, folks started to write OH- because they are so used to seeing oxygen to the left side of hydrogen in most of the molecules. The primary health effects caused by CO2 are the result of its behavior as a simple asphyxiant. A simple asphyxiant is a gas which reduces or displaces the normal oxygen in breathing air. Symptoms of mild CO2 exposure may include headache and drowsiness.
When you inhale breathe in , air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled breathe out. This process is called gas exchange and is essential to life. What are the potential health effects of carbon dioxide? Inhalation: Low concentrations are not harmful. Higher concentrations can affect respiratory function and cause excitation followed by depression of the central nervous system.
A high concentration can displace oxygen in the air. Symptoms of overexposure by inhalation include dizziness, headache, nausea, rapid breathing, shortness of breath, deeper breathing, increased heart rate tachycardia , eye and extremity twitching, cardiac arrhythmia, memory disturbances, lack of concentration, visual and hearing disturbances including photophobia.
Oxygen radicals harm the fats, protein and DNA in your body. So breathing pure oxygen is quite dangerous. Medical oxygen is used to restore tissue oxygen tension in conditions such as respiratory arrest, cardiac arrest, shock, carbon monoxide poisoning, and severe haemorrhaging, and has applications in both the hospital and pre-hospital accident response settings.
Industrial oxygen will be produced using almost ANY low VOC-producing air compressor, to increase zeolite life assuming an oxygen concentrator. Right: The oxygen that humans and animals breathe on Earth is produced by plants and other photosynthetic organisms such as algae.
Oxygen is one of the most widely used therapeutic agents. It is a drug in the true sense of the word, with specific biochemical and physiologic actions, a distinct range of effective doses, and well-defined adverse effects at high doses. Human beings must breathe oxygen.
