Sure, I can help you with that! Here are the answers to your questions:
1. The instrument used in aircraft to measure altitudes is called an altimeter. An altimeter works by measuring the atmospheric pressure, which decreases with altitude. This information is then converted into an altitude reading.
2. The metal that burns in oxygen with a dazzling light is magnesium. When ignited, magnesium reacts with oxygen in the air to form magnesium oxide, releasing a bright white light.
3. The gas liberated on heating copper carbonate is carbon dioxide. When heated, copper carbonate decomposes into copper oxide and carbon dioxide gas. The carbon dioxide gas is released as a byproduct of this chemical reaction.
4. The "king of chemicals" is a term often used to refer to sulfuric acid (H2SO4). Sulfuric acid is a strong and highly corrosive acid widely used in various industries and chemical processes.
5. The symbol for an acidic oxide can vary depending on the specific oxide in question. However, many acidic oxides are represented by the chemical symbol "O" along with the oxidation state of the element. For example, sulfur dioxide (SO2) is an acidic oxide where "S" represents sulfur and "O" represents oxygen.
6. Water (H2O) is a chemical compound, not an element. It is made up of two hydrogen atoms bonded to one oxygen atom. Water is commonly known as a compound because it is formed by a chemical union of different elements.
