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.
With a density of 1.54 g/cm 3, calcium is the lightest of the alkaline earth metals; magnesium (specific gravity 1.74) and beryllium (1.84) are denser though lighter in atomic mass. From strontium onward, the alkali earth metals become denser with increasing atomic mass.alcium is essential for living organisms, in particular in cell physiology, where movement of the calcium ion into and out of the cytoplasm functions as a signal for many cellular processes.
