Acid-a chemical substance that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red; typically‚ a corrosive or sour-tasting liquid of this kind. How does acid clean copper- “The oxygen in the air and the copper in the pennies form an oxide that coats the pennies and makes them look dirty. The acids break the copper oxide free from the penny. As we have seen experimentally‚ acid alone does not clean as well as acid and salt.” Can acid kill you?-”The actual causes of death however are not

Calcium is an essential element for the growth and development of teeth and bones. Most of the Calcium is gained from cereals‚ fruits and vegetables‚ these foods are known to have around 10 mg of Calcium per 100 grams.
