Oxygen is used in medicine to treat people with respiratory conditions, such as asthma and COPD. Oxygen can be used in water treatment plants to remove iron and sulfur from drinking water. Oxygen is an essential component of the combustion process used to power vehicles, aircraft, and other forms of transportation. Oxygen is used in …
Potassium permanganate (KMnO4) is an inorganic compound used to prepare oxygen gas in a laboratory setting. The reaction involves the oxidation of manganese (IV) oxide in an acidic solution, resulting in the release of oxygen gas. The reaction is as follows: 2KMnO4 + 3H2SO4 → K2SO4 + 2MnSO4 + 3H2O + 3O2. The reaction is …
Oxygen is a naturally occurring element that can be found in abundance on Earth. It is present in the atmosphere as a gas, and can also be found in almost all living things, in water, and in the soil. Oxygen is also found in many minerals and rocks, making up nearly half of the Earth’s …

Oxygen is an essential element for sustaining life on Earth. It is a colourless, odourless gas that makes up about 21 percent of the atmosphere. It is found in the air we breathe and is taken up by plants during photosynthesis. Animals use oxygen to metabolize food for energy and to produce carbon dioxide as …

Hydrogen is a clean-burning fuel that has the potential to reduce emissions of air pollutants and greenhouse gases. When used as a fuel, hydrogen reacts with oxygen in the air to form water and releases energy. This makes it an attractive alternative to traditional fossil fuels such as gasoline and diesel, which release harmful emissions …
Reaction between hydrogen and oxygen When hydrogen and oxygen molecules collide, they form a covalent bond to form a water molecule. The electrons from the hydrogen atoms are shared with the oxygen atoms to form the polar covalent bonds that make up a water molecule. The water molecule then separates from the two reactants and …
Collect the necessary materials. You will need a test tube, HCl, zinc granules, and a burner. Place a few granules of zinc into the test tube. Add about 10mL of HCl to the test tube. Place the test tube on the burner and heat the mixture until the zinc granules dissolve. After the zinc granules …
Hydrogen gas is a colourless, odourless, and tasteless gas. It is the most abundant element in the universe, making up about 75% of all matter. Hydrogen gas is highly flammable and is often used as a fuel in rockets and other forms of transport. It is also used to produce electricity and is a key …
Preparation of metal salts: Metal salts are used to prepare pigments, catalysts, and other inorganic compounds. Synthesis of organic compounds: Salts are used in various organic synthesis reactions such as Grignard reactions and Friedel-Crafts reactions. Formation of complexes: Salts are used to form complexes with transition metals. Electrolysis: Salt solutions are good conductors of electricity …
Salts Salts are ionic compounds that are made up of cations (positively charged ions) and anions (negatively charged ions). Common salts are sodium chloride, potassium chloride, magnesium chloride, and calcium chloride. Salts are used as preservatives, flavour enhancers, and in a variety of other food applications. They are also used for water softening and for …
