When you open a savings account you'll get a small book called a register (like a checkbook register) where you write your beginning balance (the amount you originally deposit) and all of your future deposits and withdrawals. This tool helps you keep track of how much money you have.
Hydrogen Sulfide: Nature's Chemical Helper. The main use for hydrogen sulfide is in the production of sulfuric acid and elemental sulfur. Manufacturers use sodium hydrosulfide, sodium sulfide and similar inorganic sulfides to create products such as pesticides, leather, dyes and pharmaceuticals.ydrogen sulfide is also used in chemical warfare. Many industrial entities, such as iron smelters, landfills, food processing plants and breweries, produce or use hydrogen sulfide.
Iron(II) sulfite is used in chemistry and biochemistry applications. A common use of iron(II) sulfite is in iron sulfite agar, which is a medium that can be used to grow bacteria. By using iron sulfite agar, scientists can detect the growth of a specific type of microbe that causes food to spoil. The agar is low in oxygen content, so only anaerobic microbes are able to grow in it.
