A miser is ever in want. --Greek proverb Preparing to experiment You will be provided with the following materials: Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are

Magnesium‚ sodium‚ calcium and potassium are critical for proper nerve transmission and functioning. Magnesium and phosphorus are both required for healthy bones and teeth and sulfur is needed for healthy protein molecules. Although calcium is most commonly related to healthy bones and teeth‚ it is also important

Antacid products may also contain other ingredients such as simethicone‚ which relieves gas. Antacids differ in how quickly they work and how long they provide relief. Those that dissolve rapidly in the stomach‚ such as magnesium hydroxide and sodium bicarbonate‚ bring the fastest relief. Antacids that contain calcium carbonate
