I need to make a menu for school that contains food items that contain algae. I have food like sushi, yogurt and ice cream. There&#39;s also mac and cheese, but I don&#39;t know how that would make a good meal with the above. If you have any food items or recipe ideas, that would help greatly.
Calcium is classified chemically as one of the alkaline earth elements (that is, in Group 2 of the periodic table. The metal is rather reactive. It readily forms a white coating of calcium nitride (Ca3N2) in air. It reacts with water and the metal burns with a yellow-red flame, forming largely the nitride.
Calcium is a moderately active element. It reacts readily with oxygen to form calcium oxide (CaO): Calcium reacts with the halogensâ fluorine, chlorine, bromine, iodine, and astatine, The halogens are the elements that make up Group 17 (VIIA) of the periodic table.ilk is a good source of calcium. The body uses calcium in a compound known as hydroxyapatite (Ca 10 (PO 4) 6 (OH) 2) to make bones and teeth hard and resistant to wear. Calcium has many other important functions in the human body.
